I am attending a book tour reading by researcher, Irene Pepperberg, that is promoting her new book, Alex & Me: How a Scientist and a Parrot Discovered a Hidden World of Animal Intelligence -- and Formed a Deep Bond in the Process, this Sunday evening, 2 November, in NYC. I have been trying to arrange an interview with her, and still have no idea if it will happen, but if I do manage to interview her, what questions would you like to ask her?
Unfortunately, even…

Even though most bird species form social bonds with their mates, they are not always faithful partners to each other. It's easy to figure out why male birds engage in extrapair copulations: this increases the total number of their offspring -- and this increases their reproductive fitness. But since female birds are physically capable of producing only…

This is Terry, a talking raven. His repertoire is not as varied as the Europeran Starlings I've been showing you, but he can mimic very well. [5:11]

Mozart had a pet starling whom he thought of as his musical companion. When his bird died, he had a funeral for him and invited his friends. This video should give you an appreciation for how talented these birds are as mimics [3:15]

Okay, if you are like me, you were not able to see the Nature program, Parrots in the Land of Oz, which aired on PBS on 19, 20 and 21 October. So I have dug up a few videos that give you a glimpse of what you did not see. This is a second video includes lots of footage of huge squadrons of flying budgerigars, and several species of stunningly colored rosellas and lories (which I've bred in captivity) [9:24]

So I have dug up a few videos that give you a glimpse of what you did not see. This video includes a close look at fig parrots and eclectus parrots (both of which were included in my research), along with several species of cockatoos -- black white and pink species [9:40]

Did you know that budgerigars, Melopsittacus undulatus -- erroneously known as "parakeets" in the United States -- can see UV light? Did you know that female budgerigars rely on the UV reflectance to judge the quality of potential mates? This is a fascinating little trailer about wild budgerigars from the Nature program Parrots in the Land of Oz, which airs on PBS on 19, 20 and 21 October [1:43]

Did you know that several species of cockatoos are black instead of white in color? Did you know that the Black Palm Cockatoos, Probosciger aterrimus, use tools -- tree limbs that they use to beat on their chosen nest cavity -- to attract a mate? Below the fold is a clip of the courtship of a pair of Black Palm Cockatoos from the Nature program Parrots in the Land of Oz, which airs on PBS on 19, 20 and 21 October [1:56]

There are rare days when I wish I had a TV, but today is certainly one of those days. This is a trailer from the Nature program Parrots in the Land of Oz, which airs on PBS on 19, 20 and 21 October -- that's TONIGHT! I guarantee you will enjoy this program [0:31]

People have been known to "sing for joy" and we often experience happiness when others sing for us. Additionally, birdsong has often brought joy to those who have listened, but what about the birds themselves? Do birds experience "happiness" when they hear birdsong, or when they sing for others? According to newly…
laelaps | September 29, 2008During the 19th century most discussions of the earliest known bird, Archaeopteryx, focused on its relationship to other fossil reptiles, whether or not it could fly, and what it indicated about the origins of flight. A bird would not be a bird without song, though, and at least two authors attempted to imagine what sounds the early bird might have made had it tried to sing. The first was Eden Phillpotts in the fictional book Fancy Free. In one particular chapter an Archdeacon describes a fantastic Mesozoic safari (with a tomcat named Peter by his side), describing that and as he relaxed by…

Every once in awhile, I read a paper that surprises me. Today, I read one of those papers, and it surprised me because it analyzes a phenomenon that is so obvious that I wonder why no one ever thought of studying it in a systematic and rigorous way before. I am referring to a paper that was just published by a team of…

A dragonfly has no stinger, but a European bee-eater, Merops apiaster, will beat it senseless anyway, the same way it handles its namesake prey. If the fly's wings break off, they are discarded, not eaten. The insect is then devoured as a single morsel, not as a mini-buffet of bite-size bits.

Most Americans have been actively engaged in the frustrating sport of arguing about politics, which often leads to the common refrain; "You just don't get it!" So this made me wonder why people who seem to have similar life experiences can end up with such dramatically different personal philosophies -- philosophies that ultimately affect their political views and voting behavior. Apparently, I am not the only one to wonder about such things, because a paper was just…

I just wanted to let you know that Irene Pepperberg has several speaking engagements to promote her new book, Alex & Me: How a Scientist and a Parrot Discovered a Hidden World of Animal Intelligence -- and Formed a Deep Bond in the Process (scheduled release date: 28 October 2008). As you might remember, six months ago, I was given the opportunity to review an advance reading copy of…

Birds have been disparaged publicly as "bird brains" for so long that most people have lost the ability to view them as intelligent and sentient beings. However, a group of researchers in Germany have conducted a series of studies with several captive European magpies, Pica pica, that challenge the average person's view of birds and…

You all read blogs, and many of you write them, too. But what sort of person writes a blog? Are there particular personality traits that make certain people more likely to write a blog? If so, what are those personality traits? Do you have them, too?
A team of scientists, led by psychologist Rosanna Guadagno from the University of Alabama, wondered what personality traits made some people more likely than others to write blogs. To answer…
grrlscientist | August 14, 2008Today started off painfully, but I finally managed to get out of my apartment and onto the subway so I could take care of some cats that I am petsitting right now. I figured that if my neck pain remained so bad that I had to either scream or barf, the subway was the place to do so, since I'd blend in with the natives. Fortunately, after consuming numerous analgesics like they were popcorn, I am now, several hours later, able to function reasonably well. I still am feeling pain, but fortunately nothing like earlier this week (and nothing like earlier in the day). Hopefully, the trend of…

Brood parasites are birds, fish or insects that deceive unrelated animals of the same species or different species to care for their offspring. By doing so, the parasitic parent is relieved of the energetic demands of constructing a nest and raising its young to independence…
