My hawk-headed parrot is teething. Or, because she's a parrot and thus, has no teeth, she is "beaking". Except she typically proceeds quickly from "beaking" (testing substances with her beak) to puncturing or otherwise destroying various objects -- "chomping", if you will. So, for your amusement, I have compiled a list of objects that she has "beaked" and "chomped" so far;

The 15th edition of Philosophia Naturalis, a blog carnival devoted primarily to physics, astronomy and the earth sciences, has just been published for you to enjoy. I am pleased to report that they included a piece that I wrote, so I am happy about that!

Does anyone know the purpose for this behavior?
As some of you know, I recently added a four-month-old hawk-headed (red-fan) parrot, Deroptyus a. accipitrinus, to my household. I plan to learn how to clicker-train this bird (I already have the necessary tools and books). Below the fold is an example of another young Hawk-headed parrot, named Scooter (owned by Jeannie), who was approximately eight months old in this video. This training session reinforces and refines earlier training where Scooter was taught how to place a ring on a peg, to shake hands and to place a ball in a bowl. [7:38]
The latest edition of the 1001 Cats blog carnival is now available for your reading pleasure. The editor included one of my submissions, so you've just gotta go there and see what it is!

You all are probably curious to know what is happening with my birds these days, so I shall tell you about how sex is identified in birds, such as parrots, where the sexes look the same. But wait a minute, you ask, what does an update about my birds have to do with identifying sex in parrots?
The 63rd edition of I and the Bird blog carnival is now available for your reading pleasure. It's a big one, as usual, which always pleases me -- of all the things that a person can write about on their blog, birds and birdwatching are high on everyone's list. Of course, they saw fit to include a contribution from me, too, which also makes me happy.
I thought I had linked to this video a few months ago, but apparently it disappeared during one of the typical burps that my wifi connection experiences (well, I deserve it since I am piggybacking on someone else's connection, unless I have dragged myself in to the library). Anyway, this video is truly amazing, showing what a squirrel will do to get a nut. It also has a short video clip of another squirrel that has figured out how to steal candy bars from an outdoor candy machine [1:52].
It has recently come to my attention, thanks to a friend and long-time reader, that according to a recent Harris poll, firefighters, scientists and teachers are considered to be the most prestigious professions by the public, while bankers, actors and real estate agents are perceived as the least prestigious professions.
This amusing parody of a scene in Dateline's "To Catch a Predator" TV show was banned, and so, it will make you laugh. Lesson learned? Make sure the predator isn't wearing Nikes [1:06]
