The location is important to this story in that he&rsquo;s intimately familiar with the nearby Indian Boundary Park. It&#39;s a place, he says, where he once could take his child to visit a tiny zoo that housed a llama, a bear, and other animals. In recent years, the zoo comprised a goat, a handful of chickens and some ducks.<img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/John_Lillig.JPG" style="float: right;" title="John Lillig’s interest in historical neighborhood zoos was sparked by the closure of a tiny zoo at Chicago’s Indian Boundary Park. " /></p><p>As the summer closed, the Chicago Park District shuttered the zoo and relocated the animals to the flagship Lincoln Park Zoo. But before all this came to pass, John&rsquo;s curiosity had been piqued, and he sent along this question:</p><p style="text-align: center;"><em>With the rumored closing of the Indian Boundary Park zoo, I was wondering about the history of that unusual neighborhood zoo and wondering what other zoos may have existed in Chicago other than Lincoln Park Zoo (or Brookfield Zoo). I have heard that Indian Boundary Zoo is the only remaining neighborhood zoo of what were once several neighborhood zoos. Is this true? What other zoos have existed in Chicago, where were they located, and what is there now?</em></p><p>As there had been a lot of <a href="http://www.wbez.org/news/culture/west-ridge-residents-angry-over-zoo-plans-108180">coverage of Indian Boundary this year</a>, we took on the latter half of his question. It&rsquo;s a good thing, too, since the answer required some digging.</p><p>Thankfully, John was able to provide a solid lead. He once taught literature classes, he says, and would use the <em>AIA Guide to Chicago</em> as source material. He noticed that the entry on Indian Boundary Park mentioned that it was the only<em> remaining</em> neighborhood zoo, which suggested there had once been others.</p><p>Several experts we consulted &mdash; including some who contributed to the AIA guide &mdash; didn&rsquo;t know of of any other neighborhood zoos. But, it turns out, there had been one.</p><p><strong>The West Side&rsquo;s lost zoo</strong></p><p>Chicago Park District historian Julia Bachrach directed us to Union Park, located at 1501 W. Randolph St.</p><p><a href="http://s3.amazonaws.com/wbez-assets/curiouscity/GarfieldParkZoo/GarfieldPark.html" target="_blank"><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/GParkThumb.jpg" style="float: left; height: 290px; width: 400px;" title="Click to see this design map, which shows that a zoo had also been planned for Chicago’s Garfield Park.

During a short tour, she explained what the park was like in the late 1800s, and how, like many American parks at that time, it had a zoo or, more accurately, a menagerie.</p><p>&ldquo;It really was looked at like a collection of animals, something to entertain the people who came to use the park,&rdquo; she said. &ldquo;They weren&rsquo;t at all thinking about the needs of the animals or what it would take to take proper care of them.&rdquo;</p><p>So, with Bachrach&rsquo;s good graces, and help from the Chicago Park District, the Chicago History Museum and the ghost of an urban bear, we produced <a href="http://www.wbez.org/series/curious-city/chicago%E2%80%99s-long-forgotten-zoo-108844#video">this video profile</a> of the West Side&rsquo;s long-forgotten zoo.</p><p><em>Image credits: Thanks to the Chicago Park District for permission to film at Union Park and for access to historical images posted in the facility&rsquo;s field house.</em></p><p><em>Scanned images courtesy of the Chicago History Museum.

The Chicago Department of Aviation showed off their latest &ldquo;employees&rdquo; this week, though the animals have been at work, clearing the vegetation around the airport for almost a month.</p><p dir="ltr">The group of 14 goats, five sheep, three burros and two llamas will graze inside fenced areas around the airport at least until the end of 2014. Officials say the animals were brought to the airport as a sustainable way to clean up the dense scrub vegetation that covers much of the grounds.</p><p dir="ltr">&ldquo;It gets pretty rocky under here,&rdquo; said Rosemarie Andolino, CDA commissioner. pointing to a five-acre field of grass and brush behind her. &ldquo;And there (are) areas where it kinda goes up and down and lawnmowers in many cases don&rsquo;t provide or aren&rsquo;t adequate to get to some of these areas.&rdquo;</p><p><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/goats13.JPG" style="height: 225px; width: 300px; float: right;" title="Three of O’Hare airport’s latest hires explore their new workspace. The burros are part of a herd of 25 animals that will eat vegetation around the airport to help maintain the grounds. (WBEZ/Lauren Chooljian)" /></p><p dir="ltr">Andolino said the contract for the goats won&rsquo;t exceed $19,500, and it expires by the end of 2014. The commissioner didn&rsquo;t have estimates as to how much it cost to maintain the grounds before the animals, yet a spokeswoman maintained there may be some cost savings down the road.</p><p dir="ltr">The herd won&rsquo;t be eating at the same spot everyday &mdash; Andolino says they&rsquo;ll move around to different places on the airport&rsquo;s grounds, depending on need. As for concerns about the animals during brutal Chicago winters, officials say the herd will only be out as long as weather permits.</p><p dir="ltr">Most of the animals in the O&rsquo;Hare herd come from Settler&rsquo;s Pond &mdash; a shelter for abandoned animals in Beecher, Ill. &mdash; but four of them were originally owned by Joseph Arnold, head of Central Commissary Holdings, LLC. The airport contract isn&rsquo;t technically their first job: Arnold&rsquo;s four goats used to provide milk for the goat cheese served at Chicago restaurant <a href="http://butcherandtheburger.com/">Butcher and the Burger</a>.</p><p dir="ltr"><img alt="" class="image-original_image" src="http://www.wbez.org/system/files/styles/original_image/llo/insert-images/goats17.JPG" style="float: left; height: 225px; width: 300px;" title="A day-old lamb stays close by her mother at their new home, the O’Hare International Airport.

One of the sheep even gave birth to a lamb Tuesday, and all the animals gathered around to greet him.</p><p dir="ltr">&ldquo;It&rsquo;s a little boy and his name is O&rsquo;Hare,&rdquo; said Pinky Jenota, one of the caretakers from <a href="http://www.settlerspondshelter.net/about.html">Settler&rsquo;s Pond</a>. &ldquo;He&rsquo;s doing great, he was up suckling on mom, planes flying overhead. He didn&rsquo;t flinch, Mom didn&rsquo;t move - everybody&rsquo;s content.&rdquo;</p><p dir="ltr">For now, the herd will continue munching around a five acre space on the airport grounds. Officials say they should finish that section in the next few weeks, and then it&rsquo;s on to the next spot.</p><p><em>Lauren Chooljian is WBEZ&rsquo;s Morning Producer/Reporter Follow her&nbsp;<a href="https://twitter.com/laurenchooljian">@laurenchooljian</a> .</em></p></p> Wed, 14 Aug 2013 13:38:00 -0500 http://www.wbez.org/news/herd-goats-llamas-sheep-and-burros-are-grazing-around-o%E2%80%99hare-grounds-108408 Brookfield’s baby dolphin dies suddenly http://www.wbez.org/news/brookfield%E2%80%99s-baby-dolphin-dies-suddenly-108368 <img typeof="foaf:Image" src="http://llnw.wbez.org/main-images/AP178379265245.jpg" alt="" /><p><p>Staff at Brookfield Zoo are mourning the sudden death of a newborn dolphin. The female calf was nearly a week old. She was born to a 26-year-old dolphin, Allie, one of three Brookfield dolphins who were pregnant this summer.</p><p>The baby weighed around 40 pounds at birth and measured 3 feet long. At the time, Brookfield staff said the baby was healthy and strong. But by Wednesday, veterinarians started seeing signs that the baby, who was not named, wasn&rsquo;t well. According to Dr. Michael Adkesson, Vice President of clinical medicine at the Chicago Zoological Society, the calf seemed weak, and the frequency and duration of nursing with her mother began to decline.</p><p>Adkesson says the first days of a dolphin&rsquo;s life are extremely critical, and studies have shown that deaths of young calves in the first 30 days of their life account for the largest rate of loss to dolphin populations in the world.</p><p>&ldquo;It&rsquo;s not an animal like a primate where the mom&rsquo;s able to carry the animal around, or a tiger or a lion where it&rsquo;s able to be tucked back in a den,&rdquo; he said. &ldquo;The animals really come out in the water and have to really be able to go from the first minute of birth.&rdquo;</p><p>Dolphins have to learn skills like swimming, eating, breathing and how to nurse right after birth. These are skills Adkesson says Allie was correctly teaching her offspring, but the baby&rsquo;s health still continued to decline.</p><p>Veterinarians tried to intervene, including using CPR and other tactics, but they the dolphin died early Thursday.</p><p>Adkesson says Allie is doing well, health-wise, but that it&rsquo;s hard to tell if or how she&rsquo;s dealing with the loss.</p><p>&ldquo;It&rsquo;s difficult for us to really know that, in terms of how much they grieve, &ldquo;he said. &ldquo;Obviously, we know they&rsquo;re very intelligent animals, but as far as the level of emotion that they feel, it&rsquo;s not something that we can really speak to.&rdquo;</p><p>The calf&rsquo;s autopsy report is expected to come back next week.</p><p>For now, Brookfield Zoo staff is focused on its two other mothers-to-be, and the two, hopefully healthy, babies that will be swimming alongside them in the water this fall.</p><p><em>Lauren Chooljian is WBEZ&rsquo;s Morning Producer/Reporter.

The biologist is a wildlife technician with ABC Humane Wildlife Control, and his company has captured 687 skunks so far this year in northeastern Illinois — about 200 more than last year.</p><p>Owen and the company's president, Vito Brancato, are on a skunk run in Des Plaines, a suburb near Chicago's O'Hare International Airport.</p><p>Brancato determines that an animal they just picked up is a juvenile.</p><p>"We've very lucky in that way, because we're going to at least be able to approach the skunk that is a little less likely to spray," Brancato says.</p><p>This is good news for Brancato, because skunks can spray the oily substance they use to defend themselves up to 15 feet — and their aim is good. Brancato and Owen find the skunk in a small cage in homeowner Richard Kaulback's leafy backyard.</p><p>The animal is small. Its white stripe is visible, but its head is hidden behind the trap door. Skunks are nocturnal animals — it appears to be asleep, and thankfully, its tail is down.</p><p>Kaulback has watched all sorts of wildlife traipse across his yard over the nearly 50 years he's lived in Des Plaines. This year has been a bad year for skunks.</p><p>"This is an ongoing thing all summer," Kaulback says. "Before we had a lot of raccoons, but this is the first time we've had so many skunks. This is the second [or third] skunk we've got."</p><p>Brancato says skunk populations can grow large because they don't really have any natural predators.</p><p>"Their population numbers are only controlled by highways, you know, by cars," he says. "So they do pretty well because they don't really move a lot."</p><p>It's difficult to get a real count on the number of skunks in the state, says Illinois Department of Natural Resources wildlife biologist Bob Bluett. But the department makes a best guess by counting roadkill.</p><p>"We've seen a dramatic increase," Bluett says. He adds that there was a 46 percent increase in the number of skunks from 2009 to 2010.</p><p>Companies licensed by the department to capture skunks snared 8,700 of them across the state last year, most in the Chicago area. Bluett isn't certain why the numbers are up, but skunks in the Midwest are prone to rabies, and there hasn't been an outbreak to lessen their numbers for more than 25 years.</p><p>Even so, any skunk captured in Illinois is euthanized. And because skunk numbers are up, there's more chance of a household pet tangling with one outside.</p><p>"The first thing we tell them is don't let Fido or Fifi inside," says Rebecca Fyffe, of the Wildlife Control Policy Institute.</p><p>Wash them outside with peroxide and baking soda (not tomato juice, as the old wives' tale recommends) and make sure pets have rabies vaccinations. Of course, skunks aren't all bad: They love grubs and help keep the insect population down. And for years, they've even had their own cartoon mascot, Pepe Le Pew.</p><p>But Kaulback says there's nothing adorable about a skunk.<br> <br> "They really stink up," Kaulback says. "Sometimes at night it's really bad out here."</p><p>And that's even with the door closed.</p><div class="fullattribution">Copyright 2011 National Public Radio.

The virus is so effective that the government actually sprays it on trees to help control gypsy moth outbreaks.</p><p>Now a team of scientists thinks they have discovered how the baculovirus takes control of gypsy moth caterpillars. The key is a special gene that's carried by the virus and affects the caterpillar's eating behavior, according to the team's new study in <em>Science</em>.</p><p>The discovery explains a phenomenon scientists have wondered about for decades.</p><p>Normally, gypsy moth caterpillars feed on tree leaves at night when predators including birds and squirrels can't see them. Then during the day, the caterpillars climb down and hide in the tree bark or even under leaves on the ground.</p><p>But caterpillars abandon that sensible strategy when they're infected with a baculovirus, says Kelli Hoover, an entomologist at Pennsylvania State University and the paper's lead author.</p><p>"As they get sick they climb up to elevated positions and stay there and die," she says. What happens next is pretty gruesome. "The inside of the caterpillar gets pretty much converted to millions and millions of virus particles, then there are other enzymes that cause the exoskeleton to melt. And that liquefies the caterpillar and then it can rain virus down on the leaves below."</p><p>When other caterpillars eat those leaves, they get infected too.</p><p><strong>A clever pathogen</strong></p><p>Hoover and a team of researchers suspected that the virus was taking control of the caterpillar by using a gene involved in molting, which the gypsy moth larvae must do several times as they grow. The gene also affects eating behavior because in order to molt, larvae must stop eating.</p><p>To test their hypothesis, the scientists infected some caterpillars with a baculovirus that carried the normal version of this gene and other caterpillars with a baculovirus carrying an inactivated version of the gene. Then they put the caterpillars in tall plastic containers lined with a screen.</p><p>"Every time the caterpillars were infected with the normal gene they would die at an elevated position in the container," Hoover says. "If the gene was knocked out, they didn't."</p><p>That's probably because this gene disrupts a hormonal system that tells the caterpillar when to stop eating," Hoover says. "And to feed you need to be up in the tree."</p><p>The result is devastating for the gypsy moth, but great for the virus, says David Hughes, an entomologist and biologist at Penn State and a co-author of the study. So if you look at the world from the point of view of a baculovirus, it's easy to see how it would have evolved to carry this gene.</p><p>"The most important challenge for a virus is outcompeting other viruses," Hughes says. So a virus that could make its host die in a place that spread the infection to other hosts would have a big advantage, he says.</p><p>Other scientists say the finding reveals just how clever a pathogen can be.</p><p>"Who knew that a virus would be able to manipulate the behavior of its host?" says Jim Slavicek, a research biologist with the U.S. Forest Service, who also contributed to the new study.</p><p><strong>Virus as a weapon against outbreaks</strong></p><p>Slavicek says knowing precisely how baculovirus overwhelms the gypsy moth could help scientists develop more potent strains of the virus. It could also help them determine when in the gypsy moth's life cycle it is most vulnerable to infection.</p><p>And he says all that could help bring down the cost of spraying with baculovirus. Right now, he says, land managers often use cheaper methods, such as insecticides or a deadly fungus.</p><p>"The advantage of the virus is that it is specific for gypsy moth larvae, and so it will impact no other animal, insect, plant in the treatment zone."</p><p>Gypsy moth outbreaks in the U.S. are less severe than they were a couple of decades ago, thanks to better treatments, Slavicek says. But he says the pest remains a major threat that can leave a forest bare in a matter of weeks.</p><p>During an outbreak, Slavicek says, there are so many caterpillars that their remains make some roads so slippery that road crews have to apply sand.</p><p>And if you drive on those roads at night, he says, "millions of moths will fly to the car and it can be so dense that it's like a snowstorm. You can't see what's in front of you."</p><div class="fullattribution">Copyright 2011 National Public Radio.</div></p> Sun, 11 Sep 2011 23:01:00 -0500 http://www.wbez.org/story/2011-09-11/how-clever-virus-kills-very-hungry-caterpillar-91846 Doggone It! Canine Thefts On The Rise http://www.wbez.org/story/2011-08-19/doggone-it-canine-thefts-rise-90829 <p><p>Dognappings have risen 49 percent in the U.S. in 2011, according to data gathered by the American Kennel Club.</p><p>"We believe the increase is due to economic times," Lisa Peterson, a spokesperson for the nonprofit group, which has been tracking pet theft for several years, tells <em>Weekend Edition Saturday</em> guest host Jacki Lyden.</p><p>"You have people who want pets ... but can't afford to purchase them or pay the adoption fees, so we find that they're just taking them for themselves or to give them as gifts," she says. "But then on the other hand, you have the criminal element that steals dogs and tries to sell them to unsuspecting buyers."</p><p>Peterson says the top two ways dogs are being stolen are during home invasions and out of parked cars. She cites a case in Florida where criminals took a 55-inch television set and also Boo-Boo, the Yorkshire terrier, with all of his belongings.</p><p>Tying up a dog in front of a store also makes it vulnerable for theft.</p><p>Dog theft can not only be traumatic for the owner, she says, but also for the dog.</p><p>"Dogs thrive on routine," Peterson says. "They're valued family members, so there's actually two victims to the crimes here: There's the owner, who's missing their lovable pet, and also the poor dog, [which] is suffering perhaps a little anxiety, not knowing what's going on."</p><p>Peterson says the best step dog owners can take to protect their pets, especially with recovery, is to have a microchip implanted.</p><p>There are also common-sense, close-to-home measures like not letting your dog off its leash or leaving it unattended in your yard.</p><p>In addition, Peterson says, dog owners should be cautious with information they tell strangers.</p><p>"We saw a man in Tulsa, Okla., who was approached by a man in a park, [who asked] about his adorable pit bull puppy," she says. "Then apparently the criminal followed him home and the next morning broke into the house, tied up the family at gunpoint and stole the puppy." <div class="fullattribution">Copyright 2011 National Public Radio.
