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;

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]

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?

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.

Mission Impossible Squirrel

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].
