8:08 PM | Hyraxes Upgrade Their Songs When Their Audience is Attentive
If you’re going to take the trouble to sing a song about how great you are, you probably want to make sure others are listening. It seems this is what male rock hyraxes do: they try harder to give a better performance when they have attentive listeners. Read my latest Zoologic post: Hyraxes Sing Better for Attentive Audiences .

2:56 PM | Before there were none
SUMMARY: What was it like to witness a flock of passenger pigeons flying overhead? What did this spectacle look and sound like? Start by imagining a murmuration of starlings multiplied by ten thousand times ... The passenger pigeon was driven to extinction (by people, of course) one hundred years and two days ago, when the last individual, a captive-bred individual named Martha, died at the Cincinnati Zoo on 1 September 1914. One of the first things that astounds most people... Read more

2:35 PM | Syringes with a natural aptitude for sucking blood
Not everyone likes bugs. “It was a little scary to see about a hundred bugs running in a little glass jar,” describes Dr. Christina Bauch who employed dummy-eggs to study Common Swifts. Fortunately, “extracting blood from the bugs is easy”. The swollen abdomen of the blood-fed bug is punctured with a syringe and the blood is drawn out “carefully and slowly”.

12:24 PM | The passenger pigeon by Errol Fuller – review
SUMMARY: Written by an artist and authority on extinct species, this book shares rare photographs and other visual materials to provide a general overview to the history of the extinct passenger pigeon. "Men still live who, in their youth, remember pigeons. Trees still live who, in their youth, were shaken by a living wind. But a decade hence only the oldest oaks will remember, and at long last only the hills will know.” -- Leopold Aldo, A Sand County Almanac:... Read more

6:10 PM | New Creature Feature: Meet the Thorny Devil
The thorny devil has spikes, camouflage, and a false head to protect it from predators. Plus, it can survive in its desert habitat by concentrating and drinking dew. But do they live up to their devilish name? Read my latest Creature Feature to find out: The Creature Feature: 10 Fun Facts About the Thorny Devil .

5:10 PM | Adopting Littermates… (Don’t)
The title of this post is a bit strong, but I do want to caution people from adopting two dogs from the same litter because “it’s easier” to raise two at once (ask someone with twins if it’s easier than having one child) or “we don’t want our dog to be lonely.” (Because you might […]

10:45 AM | A feathered river across the sky by Joel Greenberg – review
One hundred years ago today, the last passenger pigeon, a captive-bred adult named Martha, died at the Cincinnati Zoo. Since we knew that she was the last of her kind, her body was frozen into a 300-pound block of ice before she was shipped by train to the Smithsonian Institution, where she was skinned, dissected and preserved as a mount. Although none of the people who knew the living bird are themselves still alive today, we can still learn more... Read more

2:45 PM | Do phenotypes evolve?
In my model, ecological variation leads to nutrient-dependent ecological adaptations manifested in the morphological and behavioral phenotypes of species from microbes to man. Conserved molecular mechanisms lead from the epigenetic landscape to the physical landscape of DNA in the organized...Read more
