Dolphins can swim circles around them when it comes to long-term memory.</p><p>Scientists in a new study repeatedly found that dolphins can remember the distinctive whistle &mdash; which acts as a name to the marine mammal &mdash; of another dolphin they haven&#39;t seen in two decades.</p><p>Bailey the dolphin hadn&#39;t seen another dolphin named Allie since the two juveniles lived together at the Dolphin Connection in the Florida Keys. Allie ended up in a Chicago area zoo, while Bailey got moved to Bermuda. Yet 20 1/2 years later, Bailey recognized and reacted to Allie&#39;s distinctive signal when University of Chicago researcher Jason Bruck played it on a speaker.</p><p>Other dolphins had similar steel-trap memories. And it&#39;s not just for relatives. It&#39;s non-kin too.</p><p>&quot;It&#39;s mind-blowing; I know I can&#39;t do it,&quot; Bruck says. &quot;Dolphins in fact have the longest social memory in all of the animal kingdom because their signature whistle doesn&#39;t change.&quot;</p><p>Studies have shown that monkeys can remember things for about four years and anecdotes have elephants remembering for about 10, Bruck says in a paper published Wednesday by Proceedings of the Royal Society B. But remembering just a sound &mdash; no visuals were included &mdash; boggles even human minds, he says.</p><p>For Bruck, 33, it&#39;s as if a long-lost classmate from middle school called him up and Bruck would be able to figure out who it was just from the voice.</p><p>Faces, yes, yearbook pictures, definitely, but voices that change with time, no way, Bruck says.</p><p>&quot;We&#39;re not as acoustically as adept as dolphins,&quot; Bruck says. It helps that dolphins have massive parts of the brain that are geared toward sound.</p><p>Bruck thinks dolphins have the incredible memory because it could help them when they approach new dolphins on a potential group hunt. And even more likely it probably allows dolphins to avoid others that had mistreated them in the past or dominated them, he says.</p><p>Male dolphins had a slightly better memory than females and that&#39;s likely a case of worrying about dominance. Some males would hear Lucky or Hastings, dominant males, that they hadn&#39;t heard in years and they&#39;d react by going into an aggressive S-posture or screaming their own signatures, Bruck says.</p><p>Outside dolphin researchers praised the work, saying the next effort is to see whether somehow the dolphins visualize their old buddies when they hear the whistle. Bruck says he is working on that.</p><p>&quot;The study raises some very interesting questions and hints at the wider importance of long-term social memory in nonhuman mammals and suggests there are strong parallels between dolphin and human social recognition,&quot; said dolphin researcher Stephanie King at the University of St. Andrews in Scotland.</p></p> Wed, 07 Aug 2013 10:59:00 -0500 http://www.wbez.org/news/u-c-study-finds-dolphins-display-memory-better-elephants-108319 3 Brookfield Zoo dolphins expecting http://www.wbez.org/news/culture/3-brookfield-zoo-dolphins-expecting-107293 <img typeof="foaf:Image" src="http://llnw.wbez.org//main-images/Spree, Tapeko, and Allie Bottlenose Dolphins-2 (2).jpg" alt="" /><p><p>Chicago Zoological Society officials say three Brookfield Zoo bottlenose dolphins are pregnant.</p><p>Officials said Monday that 26-year-old Allie, 31-year-old Tapeko and 10-year-old Spree are due to give birth this summer and fall.</p><p>Allie has had two previous calves and Tapeko, three. But first-time mother Spree will require extra care as her pregnancy will have greater risks, as with other mammals.</p><p>Officials say zoological society field scientists, veterinarians and husbandry managers work together to improve the well-being of dolphins at Brookfield Zoo and in the wild.</p><p>Society associate veterinarian Jennifer Langam says prenatal care for the dolphins is similar to that for human moms, which includes ultrasound exams and blood tests.</p><p>Factors tracked during daily activities include weight gain, body temperature, diet and blubber thickness.</p></p> Tue, 21 May 2013 14:48:00 -0500 http://www.wbez.org/news/culture/3-brookfield-zoo-dolphins-expecting-107293 Baby giraffe makes debut at Brookfield Zoo http://www.wbez.org/news/culture/baby-giraffe-makes-debut-brookfield-zoo-103981 <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/baby%20giraffe%202.jpg" style="height: 930px; width: 620px;" title="(Courtesy of the Brookfield Zoo)" /></div><p>A baby giraffe has made his debut at Brookfield Zoo in suburban Chicago.</p><p>Zoo officials say the baby boy was born Nov. 12 but didn&#39;t go on public display until Wednesday. His mother is five-year-old Arnieta and his father is four-year-old Hasani. The baby boy weighs 140 pounds and is six feet, two inches tall.</p><p>The baby is the 58th giraffe born at Brookfield Zoo. Zoo officials say it&#39;s an important birth because he is the first offspring for Arnieta and Hasani. Hasani arrived at Brookfield Zoo in 2010 and is on a breeding loan from Lee Richardson Zoo in Garden City, Kan.</p><p>Giraffes give birth standing up after 14 1/2-month-long gestation period.</p><p>When fully grown, the baby could potentially be 18 to 19 feet tall.</p></p> Thu, 22 Nov 2012 08:16:00 -0600 http://www.wbez.org/news/culture/baby-giraffe-makes-debut-brookfield-zoo-103981
