The audio story includes interview excerpts from the Curious City Fecal Matters! live event of March 2015.&nbsp;</em></p><p>There&rsquo;s a natural cycle to urban life that can&rsquo;t be ignored; as the snow melts away and the citizenry emerges from winter burrows, residents spend more time outdoors, and with that, there&rsquo;s more opportunity to ponder the animals&rsquo; rhythms and cycles, including the less seamly ones.</p><p>Chicagoan Kelley Clink reflected on life&rsquo;s natural processes, particularly as she potty-trained her pup two springtimes ago. She wondered how poop management worked on a larger (Ok, institutional) scale, and she then sent us this question:</p><p dir="ltr" style="text-align: center;"><em><a href="http://curiouscity.wbez.org/#!/archive/question/33">What happens to all the, um, &#39;animal waste&#39; from the Lincoln Park Zoo?</a></em></p><p>&ldquo;My dog at the time was pooping in various places,&rdquo; Clink said. &ldquo;Sometimes I&rsquo;d pick it up and throw it in a dumpster, and sometimes if he pooped on my rug I&rsquo;d take some toilet paper and flush it inside. So it made me think, &lsquo;Gosh, with all these animals are they flushing it? Putting it in the dumpster? Where is it going?&rsquo;&rdquo;</p><p>Well, the answer can be summed up like this: Lincoln Park Zoo tosses the poo, it studies the poo, and it stores the poo (in the hopes of studying the poo even more someday). That may not be returning poo to &ldquo;the great cycle of life,&rdquo; but it&rsquo;s how the stuff is dealt with, regardless. If you can hold your nose for a short bit, here are the details.</p><p><span style="font-size:22px;">Toss it</span></p><p>The first thing to note is that zoo poop is not so easy for journalists to access, so you&rsquo;re spared first-hand accounts of the nitty-gritty, behind-the-scenes scraping, shoveling and the like. The Lincoln Park Zoo tells us raw animal waste is considered biohazardous, so we could not actually go anywhere near it to follow its journey.</p><p>But, the Lincoln Park Zoo confirms that the bulk of the animal waste is pretty much handled like garbage; it&#39;s hand-removed by staff, thrown into dumpsters or bags, and compacted along with all the other garbage, according to General Curator Dave Bernier. He says the zoo uses a waste management company to cart everything away.</p><p>Some zoos have opted to<a href="http://www.youtube.com/watch?v=kjfNVEvRI3w"> use the feces for composting</a>, even <a href="http://www.zoo.org/page.aspx?pid=2001">selling the material as fertilizer</a> in their gift shops for use in home gardening. Bernier said he&#39;s heard talk of doing similar things at Lincoln Park, but he says there are some considerable barriers to doing so. He said it would require hiring staff and the park currently doesn&#39;t have space or a back-lot for such an operation. Besides, Bernier said, &quot;We have a hard time getting people to like the smell of our aardvark, I can&#39;t imagine they&#39;d like this feces brewing somewhere.&quot;</p><p><span style="font-size:22px;">What can you do with zoo poo? Study it!</span></p><p>But the old heave-ho doesn&rsquo;t apply to the zoo&rsquo;s entire supply of animal feces. Dave Bernier says a portion of the poo is studied for insights into the animals&rsquo; physical and emotional well-being. In some respects, Bernier says, the zoo treats feces as a &quot;management tool&quot; to monitor animal health. For example, zoo keepers look for obvious changes in the consistency, color or amount of feces animals produce.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/8%20CAMELS.jpg" style="height: 465px; width: 620px;" title="Normal Bactrian Camel waste should look like chocolate-glazed donut holes, explains Bernier. When one of the camels had a loose stool, the zoo studied its fecal matter and learned it was eating too much of the free-growing plant foliage. (WBEZ/Logan Jaffe) " /></div><p>Bernier says that a few years ago the zoo &quot;had a camel that had loose stool. Normally they&#39;re well-formed pellets of stool &mdash; just think of chocolate-glazed donut holes.&quot; He explains that staff looked into that camel&#39;s diet and realized it was eating too much of the free-growing plant material in its space.</p><p>&quot;So we ended up cutting back some of the plants they could reach in their exhibit and then their stool normalized again,&quot; he said.</p><p>But the zoo keepers take an even closer look at feces, too, performing diagnostic tests in an on-site laboratory.</p><p>Rachel Santymire, director of the zoo&rsquo;s Davee Center for Epidemiology and Endocrinology, oversees and studies about 10,000 poop samples a year from about 50 animal species at the zoo. Santymire says each sample is a clue into an animal&rsquo;s emotional health.</p><p>&ldquo;Animals can hide certain behaviors,&rdquo; Santymire said. &ldquo;I can look inside the animal &mdash; they can&rsquo;t lie to me! &mdash; and I know exactly how they&rsquo;re reacting to whatever they&rsquo;re encountering &hellip; all from poop.&rdquo;</p><p>For example, Santymire can tell whether an animal is pregnant by detecting changes in its hormonal levels. She can also get a sense of whether an animal feels stressed out &mdash; all by looking for the hormone cortisol.</p><p>Bernier says those fecal tests can be used to make important decisions, <a href="http://www.tandfonline.com/doi/abs/10.1080/10888705.2011.576968">such as changing an animal&#39;s living situation</a>.</p><p>&quot;I had a singly-housed female antelope which normally lives in groups and she seemed perfectly fine. But she was alone because her cage-mate had recently passed away,&quot; Bernier said.</p><p>He wondered if introducing another antelope to her cage would ultimately be a positive change, or if it would stress her out. They tested the theory by slowly introducing a new antelope friend. All the while, staff collected and tested samples of both animals&rsquo; feces &mdash; before the introduction and after it. Bernier said the cortisol levels spiked and then dipped after the introduction.</p><p>&quot;But ultimately both of their stress hormone levels went down below their baselines when they were together,&quot; Bernier said. He adds that, without this kind of testing, staff could not have known whether it was a positive or negative change because the animals showed no outward signs of stress.</p><p>&quot;Animals are meant to mask any kinds of injuries illnesses or deficiencies because a lot of them are prey animals or have to survive in a social setting,&rdquo; Bernier said.</p><p>But, as zoo staff often say: Hormones don&rsquo;t lie.</p><p><span style="font-size:22px;">Institutional poo hoarders</span></p><p>With about 10,000 poop samples a year making their way through Santymire&rsquo;s lab, you&rsquo;d suspect she has a complex storage system for all that waste; however, Santymire says the setup&rsquo;s quite simple. It involves refrigeration. And lots of it.</p><p>First, the animal care staff collects samples from the animals like you might pick up after a dog, using sealed, plastic bags. The staff puts those samples in refrigerators all around the zoo, and Santymire collects the new material every month. She then weighs out portions of the poop, shoves them into test tubes, and then places the tubes into carefully labeled boxes, according to species. Santymire says each box holds 100 poop samples, and she&rsquo;s got 10 standard, 21-cubic-foot freezers full of poo boxes.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/lpzoo%20strorage.jpeg" style="height: 278px; width: 620px;" title="The zoo's endocrinology lab studies about 10,000 poop samples a year and stores them in 10 freezers throughout the grounds. (Photo courtesy Lincoln Park Zoo)" /></div><p>Why keep all that poop at the ready? Well, Santymire says, it stays fresh for a long time, making the samples good material for follow-up questions she comes up with.</p><p>&ldquo;Instead of throwing away samples when we&rsquo;ve published our results, I look at the tubes and say, &lsquo;Wow, I can ask and answer another question with these poop samples. I cannot throw them away. I admit it,&rdquo; she said.</p><p><span style="font-size:22px;">The kicker: What are the grossest offenders?</span></p><p>Questioner Kelley Clink wasn&rsquo;t just interested in the Lincoln Park Zoo poo&rsquo;s ultimate destination. She tossed us a quick follow-up that we couldn&rsquo;t resist: Which animal is the worst to clean up after?</p><p>We put the question to both Santymire and Bernier.</p><p><strong>Santymire&rsquo;s nominee: <a href="http://en.wikipedia.org/wiki/Fishing_cat" target="_blank">The Fishing Cat</a></strong></p><p>&ldquo;Imagine a cat that eats mostly fish.

But it didn&rsquo;t take long for him to be disabused.</p><p>&ldquo;I saw it twitch real quick,&rdquo; he says. &ldquo;The next thing I knew, it grew wings and it was flying around my ankles and then right past my face.&rdquo;</p><p>It was a bat, in broad daylight, just doing its bat thing downtown. Soon after, Rory collected himself from fright and submitted these questions to Curious City:</p><p dir="ltr" style="text-align: center;"><em>How many bats are in Chicago&rsquo;s Loop? What are their favorite hangouts?</em></p><p>Spoiler alert: Our experts say we can&rsquo;t pinpoint exactly how many bats call the Loop home. Nor can we locate particular buildings the critters like, either. (Alas, someone else will have to explore whether the <a href="https://www.flickr.com/search/?l=commderiv&amp;q=wrigley%20building%20chicago" target="_blank">gothic tower atop the Wrigley Building </a>acts a bat-magnet). But experts<em> can </em>say which types of environments Chicago&rsquo;s bats like to hang out in and how popular those sites are.</p><p>The takeaway is that these furry fliers are likely closer than you think. And, beyond that: All this bat activity&rsquo;s a good sign, given that there&rsquo;s an ominous threat to their very existence.</p><p><span style="font-size:22px;">Where local bats <em>aren&rsquo;t</em></span></p><p>In 2012 researchers at the Lincoln Park Zoo&rsquo;s Urban Wildlife Institute embarked on a study to measure the Chicago-area bat population. They wanted to learn more about which bat species call Chicago home (or were at least recurring squatters), gauge their numbers and determine their favorite haunts, all with the hopes of keeping close tabs on bat species affected by the fatal spreading disease called &ldquo;<a href="https://www.whitenosesyndrome.org/" target="_blank">White Nose Syndrome</a>.&rdquo;</p><p>By 2013, the scientists had set up 18 bat detectors in various habitats around Cook and Kane counties: forest preserves, golf courses and at the Lincoln Park Zoo&rsquo;s Nature Boardwalk. As much as we hate to let Rory down, none of these detectors was in the Loop.</p><p><a href="http://interactive.wbez.org/curiouscity/bats/" target="_blank"><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/eastern-pipistrelle-little-guy.png" style="float: right; height: 116px; width: 180px;" title="An eastern pipistrelle." /></a>That&rsquo;s for several reasons.</p><p>The first one: Bats probably aren&rsquo;t hanging out downtown. Liza Lehrer, a research coordinator at UWI, says bats might fly through the Loop looking for food, but likely wouldn&rsquo;t make a home in urban infrastructures like skyscrapers. But if we were to try to pinpoint a bat hangout in the Loop, Lehrer says, be on the lookout for older, cozier buildings with lots of nooks and crannies.</p><p>&ldquo;They like old churches, barns, things like that &mdash; areas with lots of older architecture with attics that are easy to get into through roofs,&rdquo; Lehrer says. &ldquo;Maybe the Bucktown, Wicker Park areas, but I&rsquo;m sure anywhere around the city where they can use those spaces they&rsquo;re probably using them.&rdquo;</p><p>Lehrer says it&rsquo;s hard to put a number to how many bats hang out in urban infrastructure. But she wouldn&rsquo;t be surprised if there were 1,000 or more bats living in older Chicago neighborhoods.</p><p>&ldquo;Maternity colonies can have hundreds of individuals in one colony,&rdquo; she says. &ldquo;So it&rsquo;s very possible there are thousands in the Chicago area for sure.&rdquo;</p><p>The second reason why UWI didn&rsquo;t place bat detectors in the Loop has to do with sound.</p><p>Julia Kilgour, a former UWI bat researcher, says the sheer noisiness of the Loop makes it a bad environment to pick up bat calls, and it&rsquo;s even noisier for the bats themselves.</p><div class="image-insert-image "><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/sonobat.jpg" title="A screenshot from Sonobat software that shows bat call frequency and species. Researchers can use this to determine how active certain sites are. (Photo courtesy UWI)" /></div><p>If you were sick the day they talked about <a href="http://animals.howstuffworks.com/mammals/bat2.htm" target="_blank">echolocation</a> in school, here&rsquo;s how bats navigate the world. Their eyesight isn&rsquo;t so hot, but their hearing is. Bats send out ultrasonic calls, which bounce off trees, buildings and prey. They listen to these echoes to locate who and what is around them.</p><p>Echolocation is not a problem in quiet, rural areas; but in dense, urban areas like the Loop, bats have a harder time pulling it off.</p><p>Rory himself was on to that explanation: &ldquo;I imagine if I&rsquo;m a chic urban bat and looking for a place to live, the Loop would be accommodating ... but it would be noisy.&rdquo;</p><div class="image-insert-image "><span style="font-size: 22px;">Where the bats </span><em style="font-size: 22px;">are</em></div><p>UWI researchers had plenty of other locations to gather data from; they&rsquo;ve analyzed thousands, if not millions, of bat calls gathered from forest preserves and golf courses around the Chicago area. Liza Lehrer says she&rsquo;s counted up to 3,000 calls from one detector in a single night.</p><p><a href="http://interactive.wbez.org/curiouscity/bats/" target="_blank"><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/forgotten bat 2.png" style="height: 242px; width: 180px; float: left;" title="A silver-haired bat" /></a>&ldquo;What&rsquo;s really exciting about what we&rsquo;ve found so far is we see a lot of bats in Chicago, both in urban and rural areas,&rdquo; she says. &ldquo;We actually see more bats using Cook County sites in the height of the summer, but out in rural areas we saw more consistent numbers.&rdquo;</p><p>Another interesting finding? Bats really like golf courses.</p><p>&ldquo;You may not consider that an area for wildlife, but there&rsquo;s lots of bat diversity in golf course sites,&rdquo; Lehrer says.</p><p>Golf courses aren&rsquo;t as dense as the city&rsquo;s forest preserves and typically contain a small body of water, so they appeal more to tree-roosting bats, such as the hoary bat and the eastern pipistrelle.</p><p><a href="http://interactive.wbez.org/curiouscity/bats/" target="_blank">(To see a breakdown of favorite bat habitats around Chicago, check out our visualization by artist Erik Rodriguez, based on research provided by the UWI).</a></p><p>But the finding Lehrer says she&rsquo;s most excited about is that all seven species common to Northeastern Illinois have been detected at the <a href="http://www.lpzoo.org/nature-boardwalk" target="_blank">Lincoln Park Zoo&rsquo;s Nature Boardwalk</a>, a mere three miles north of the Loop.</p><p>&ldquo;[Bats are] living right here in Chicago, right in the middle of the city, right here at the zoo,&rdquo; Lehrer says. &ldquo;We&rsquo;re fortunate to have an amazing array of green space in the city so they&rsquo;re able to take advantage of that as much as possible.&rdquo;</p><p><span style="font-size:22px;">The dreaded white-nose</span></p><p>Finding all seven bat species so close to a dense metropolis is especially exciting, Lehrer says, because several species are directly threatened by <a href="https://www.whitenosesyndrome.org/" target="_blank">white-nose syndrome</a>.</p><p>A bat afflicted by the white fungal disease can wake up early during winter hibernation. Affected bats become active right when nature designed them to conserve energy and do as little as possible: when food stores are low and temperatures are dangerous. Lehrer draws an analogy that Chicago-area residents can certainly relate to. &ldquo;If you think about if you emerged from hibernation during our polar vortex,&rdquo; she says, &ldquo;there&rsquo;d be nothing for you to eat. It&rsquo;d be very difficult for you to survive if you were a bat. So, thats what&rsquo;s happening. They emerge from wintering spots and aren&rsquo;t able to survive or find food.&rdquo;</p><div class="image-insert-image "><a href="http://interactive.wbez.org/curiouscity/bats/" target="_blank"><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/LITTLE BROWN BAT WEB.jpg" style="height: 430px; width: 620px;" title="Little brown bat populations, illustrated above, have been decimated by white-nose syndrome in the northeastern U.S., but researchers have detected bat calls from them at the Lincoln Park Zoo's nature boardwalk." /></a></div><p>Since white-nose syndrome spreads when bats are hibernating in close proximity, Lehrer says, &ldquo;some caves have found up to 90 to 100 percent mortality.&rdquo; According to the U.S. Fish and Wildlife service, the disease has killed millions of bats across the U.S. and Canada. There have been <a href="https://www.whitenosesyndrome.org/resources/map" target="_blank">confirmed sightings</a> in Illinois, as well as several neighboring states.</p><p>The disease is <a href="https://www.whitenosesyndrome.org/about/bats-affected-wns" target="_blank">hitting some bat species harder than others</a>. Of the seven species that call the Chicago area home, the big brown bat (<em>Eptesicus fuscus</em>), the little brown bat (<em>Myotis lucifugus</em>), and the tri-colored bat (<em>Perimyotis subflavus</em>) have been susceptible.</p><p>The UWI study is one effort to monitor bat populations, health and behavior while scientists find cures for the disease.</p><p>So while bats may be on the top of the list of scary creatures for many Chicagoans, the scarier proposition is that there would be no bats left. At least, that&rsquo;s how Rory Keane feels about it.</p><p>&ldquo;When you come across something really puzzling like WNS &hellip; it&rsquo;s troublesome,&rdquo; he says. &ldquo;If it spells the end for bats it&rsquo;s just one more fixture in the ecosystem that&rsquo;s going to throw things out of balance for us as we experience it every day.&rdquo;</p><p>He points to a scene most Chicagoans can relate to. &nbsp;</p><p><a name="bio"></a>&ldquo;If you&rsquo;re driving down Lake Shore Drive and it&rsquo;s a clear day and you can see the skyline in front of you,&rdquo; he says, &ldquo;you marvel at the success we&rsquo;ve built up around us. &hellip; But could it have all worked out without the contributions of even these tiny, erratically-flying, illogical mammals we call bats?&rdquo;</p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/rory%20mug%20FOR%20WEB.jpg" style="float: left; height: 199px; width: 200px;" title="(Photo courtesy Rory Keane)" /><span style="font-size:22px;">Our question comes from: Rory Keane</span></p><p>Chicagoan Rory Keane got us looking into bat habitat a few years after he nearly stomped on one that was hanging out in the Loop. A graduate from Northwestern&rsquo;s Medill School of Journalism, he&rsquo;s worked as an English teacher in China and is currently working as a digital marketer in Chicago.</p><p>&ldquo;I guess you could characterize me as a curious person,&rdquo; he says. &ldquo;I have a little bit of a curiosity when it comes to travel and seeing the world from a different perspective.&rdquo;</p><p>So, he&rsquo;s no stranger to new experiences, but he still didn&rsquo;t expect to get a new perspective from that one, tiny bat in his hometown.</p><p>&ldquo;It was already an incredibly precious encounter given that you would never expect it,&rdquo; Rory says of the eastern red bat he nearly squashed. &ldquo;It took a bat to startle me into realizing what was going on around me [in the natural world] on an everyday basis.&rdquo;</p><p>Did we mention Rory also does a fantastic Werner Herzog impression?

Carole thinks she&rsquo;s &ldquo;genetically predisposed&rdquo; to be interested in birds, after growing up watching them at the bird feeder her mother put up in their backyard.</p><p>That lifelong interest &mdash; as well as a recent hawk sighting of hers &mdash; led Carole to ask Curious City:</p><p style="text-align: center;"><em>Is anybody studying the increasing hawk activity in Chicago&rsquo;s neighborhoods?</em></p><p>Her question covers several topics, including the people on the lookout for hawks, but we thought we owed it to Carole to suss out whether &mdash; in fact &mdash; there&rsquo;s a local population of hawks on the rise. While tracking this down, we came across a bit of a wildlife conservation success story.</p><p><strong>(Chicken) hawks on the increase</strong></p><p>Observant bird-watchers like Carole suspect there are more hawks in the area, but have professional researchers taken note, too?</p><p>Well, there are several local researchers who study and document the goings-on of wild critters in our urban and suburban environment, but when it comes to studying hawks specifically, we can turn up only one: Mason Fidino of the Urban Wildlife Institute. Founded in 2009, the Institute&rsquo;s part of Chicago&rsquo;s Lincoln Park Zoo.</p><p>For the first part of Carole&rsquo;s question, does Fidino&rsquo;s work show that there is an increased hawk population in Chicago? &nbsp;&ldquo;Yes! It&rsquo;s a pretty resounding yes,&rdquo; he says. Fidino is recreating a historic bird count that was conducted in Lincoln Park from 1897 to 1903, and he&rsquo;s able to compare current bird populations with this century-old data. One hawk in particular stands out in Fidino&rsquo;s studies: the Cooper&rsquo;s Hawk, which he describes as the &ldquo;most abundant,&rdquo; frequently seen bird of prey in Lincoln Park. This is quite a change from the historic study, where the Cooper&rsquo;s Hawk &ldquo;was not seen whatsoever.&rdquo;</p><p>These birds were once widely viewed as a menace and even hunted in the past. Nicknamed &ldquo;chicken hawks,&rdquo; they were despised as chicken thieves.</p><p>Fidino points me to the historical record, where we can find sentiments from people like Alfred O. Gross, a man who eventually became a respected ornithologist. In 1906 Gross conducted a bird census in Illinois. He described the Cooper&rsquo;s Hawk as a &ldquo;handsome robber&rdquo; with a &ldquo;perverted taste for chicken.&rdquo;<a href="http://www.thinglink.com/scene/502929837053181952" target="_blank"><img alt="" class="image-original_image" src="http://llnw.wbez.org/styles/original_image/llo/insert-images/Cooper's Hawk inline image.jpg" style="height: 443px; width: 350px; float: right;" title="Rendering of a Cooper's Hawk, otherwise known as a Chicken Hawk, by Chicago artist Diana Sudyka." /></a></p><p>Later, the <a href="http://www.epa.gov/pesticides/factsheets/chemicals/ddt-brief-history-status.htm" target="_blank">pesticide DDT </a>also damaged their population. Cooper&rsquo;s Hawks mostly eat other birds, so they would have ingested all of the DDT concentrated in their prey animals. The pesticide caused eggshells to thin, and they would crack under the weight of the large birds. The Cooper&rsquo;s Hawk was even on Illinois&rsquo; endangered species list from 1977 through 1997.</p><p>Eventually, human interference loosened: We stopped shooting &ldquo;chicken hawks,&rdquo; we banned DDT, and, according to Fidino, the hawks came back.</p><p><strong>How easy is it to see one?</strong></p><p>Mason Fidino says you can find hawks in the city if you look for them &mdash;especially Cooper&rsquo;s Hawks. &ldquo;Often enough you&rsquo;ll see hawks circling around,&rdquo; he says, adding you can also spot them perched on tree branches. Fidino advises curious residents to &ldquo;spend some time on a weekend, take a walk out in a park. You should be able to see a bird of prey or two.&rdquo;</p><p>Fidino says he sometimes even sees hawks hunting in Chicago&rsquo;s Lincoln Park. If you see something quickly zooming towards the ground, it could be a hawk looking for lunch. For his part, Fidino will see the hunting bird just out of the corner of his eye. It will be &ldquo;this really quick movement going from the top of the tree downwards to whatever it&rsquo;s trying to catch. Then its talons go out, and it grabs what it&rsquo;s going after and then it&rsquo;ll swing back up or land with it,&rdquo; he says.</p><p>Cooper&rsquo;s Hawks have nests that are smaller than squirrels&rsquo; bulky, leafy nests. Another way to catch a glimpse of a hawk is to keep an eye on their nest &ldquo;and see who shows up,&rdquo; Fidino says.</p><p><strong>A possible hawk menace?</strong></p><p>It&rsquo;s reassuring to see a previously struggling species thrive, but perhaps you&rsquo;re wondering about a downside. Cooper&rsquo;s Hawks survive mostly by hunting smaller birds. Will we be hearing about a &ldquo;save the chickadees&rdquo; campaign in a few years?<img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/Flickr_%20Mike%20Ormsby_Copper%27s%20Hawk.jpg" style="height: 346px; width: 275px; float: left;" title="Cooper's Hawks look very similar to Sharp-shinned Hawks, but differences can be detected with key details like tail feather shape. Our field guide gives more clues for distinguishing the species. (Flickr/Mike Ormsby)" /></p><p>Fidino is not worried. Populations of top predators like hawks tend to be much smaller than their prey species. The relatively few chickadees or pigeons who end up being a hawk&rsquo;s lunch shouldn&rsquo;t significantly damage their population. The various bird populations, Fidino says, &ldquo;should be able to work themselves out into what you&rsquo;d kind of consider an equilibrium.&rdquo;</p><p>Hawks mostly hunt birds, although they&rsquo;ll also dine on small mammals. It&rsquo;s very rare for pets to come under attack by raptors. However, when pressed, Fidino will advise that owners of small pets might want to &ldquo;be mindful of the species that they&rsquo;re adding to the ecosystem,&rdquo; and perhaps not leave especially tiny dogs unattended in the back yard.</p><p><strong>The adaptation game</strong></p><p>Carole wondered if we&rsquo;re seeing more hawks in Chicago because they&rsquo;ve developed adaptive behaviors to live in cities. Dr. Seth Magle, the Urban Wildlife Institute&rsquo;s director, says that&rsquo;s not the case. He described the concept of &ldquo;habitat analogs,&rdquo; where parts of our built environment function to animals the way their natural habitat does.</p><p>Magle provides the example of pigeons. &ldquo;They&rsquo;re cliff-dwelling species, but in cities we build these big tall buildings, so to pigeons they may kind of look like cliffs,&rdquo; and thus look like home, he says.</p><p>Hawk behavior is similar. Red-tailed hawks like to perch on something tall, and power lines along the highway function perfectly for that task. Other species, including the Cooper&rsquo;s Hawk, feel perfectly at home in trees near humans. And why not, now that we city-dwellers and suburbanites are more interested in watching hawks than shooting them.</p><p><em>Special thanks to the <a href="http://www.birds.cornell.edu" target="_blank">Cornell Lab of Ornithology</a> for permission to use images, bird listings and sound for this story.</em></p><p><em>Katie Klocksin is an independent producer.

He gets to the zoo at 6 a.m.., something he has done almost every day for nearly four decades, ever since he was 23 and came here from New York to become curator of birds&mdash;the youngest curator in the zoo&#39;s history.</p><p>Birds were the zoo&rsquo;s first animals. They arrived in 1868, a pair of mute swans that were a gift from New York City&#39;s Central Park. They came by train; it took two days.</p><p>Many things have changed at the zoo during the last 144 years, but one wonderful thing has not: It&#39;s free, one of only three major U.S. zoos (the others are in Washington, D.C., and St. Louis) that charge no admission.</p><p>Those two swans soon multiplied to 13, and by 1874 the animal population swelled to 48 birds and 27 mammals. That year a bear was bought for $10 and the Lincoln Park Zoological Gardens was officially formed, making our zoo-though arguments come from Philadelphia&mdash;the first in the U.S.</p><p>It has grown&mdash;more animals, more land-over the years. But it has always bee&mdash;and remains&mdash;a special slice of the city.</p><p>A zoo, especially one as accessible and democratic as Lincoln Park&#39;s, sits in a pleasant spot in one&#39;s memory and provides a strong thread through one&#39;s life. It is a place where virtually every Chicago-area child is taken by his parents and where, in turn, these children take their children and their children and on and on through the generations.</p><p>It is an early morning last week. Outside, people stroll. Inside and outside, animals prowl. Lincoln Park Zoo shakes its furry, feathered self to life.</p><p>Kevin Bell is there, of course.</p><p>Bell says, &quot;For a little while, my time is my own. This hour is mine, and I spend it with the birds.&rdquo;</p><p>We are outside and a couple of tiny sparrows, prosaic city birds free to scurry about the trees above Bell&#39;s head, make some funny noise&mdash;you know, that chirping noise that always sounds happy. They fly off and Bell watches them, until they are but specks in the city sky.</p></p> Mon, 15 Oct 2012 12:39:00 -0500 http://www.wbez.org/blogs/bez/2012-10/bird-man-lincoln-park-zoo-103132 Chicago zoo helps vaccinate dogs in Tanzania http://www.wbez.org/science/environment/chicago-zoo-helps-vaccinate-dogs-tanzania-98574 <p><p>Officials with a Chicago zoo say they've vaccinated a million dogs in Tanzania as part of a project to eliminate rabies and save endangered carnivores in the Serengeti National Park.</p><p>The Lincoln Park Zoo says its project began in 2003 and the zoo's Serengeti Health Initiative team has worked in villages in northern Tanzania to administer the donated vaccines.</p><p>Zoo officials announced their one millionth vaccination in a news release Wednesday.</p><p>Steve Thompson is the zoo's vice president of conservation.
