Whosits and Whatsits Galore

As pretty and majestic as birds are, I find it difficult to sense much of an interspecies connection when I look into their rather steely eyes. Feeling connected is what makes me care, so I was recently excited to learn about an avian species Jared Diamond has called "the most intriguingly human of birds." The bowerbird, which lives in and near Papua New Guinea (like so many gems of evolutionary biology), is anthropomorphous to say the least.

Whereas many other birds sport flashy colors on their feathers to attract mates, bowerbirds are dull and brown like us. They must therefore accumulate their flashiness instead - also like us.

Males build elaborate huts, then decorate them with enormous collections of shiny and colorful trinkets. Depending on individual tastes they may choose to adorn their premises with piles of berries, stones, dead beetles, nice looking leaves, glass, brightly colored trash, and so on. The birds' collections are fastidiously arranged and maintained.

With their goods on display, the males await the arrival of females, whose role it is to assess their assorted items. On the basis of the aesthetic quality of a male's possessions, the female chooses whether to mate with him... or to fly on in search of sexier piles.

  2. Here's a raven annecdote: a short while ago Paul found a freshly killed raven on our country road. He brought it home to me, since he knows I'm a raven fanatic. I studied it, then put the carcass over our back fence. Sometime later I dashed outside on hearing a wild cacophony of birds. There in the air, circling in a Hitchcockian menace were dozens of ravens. They filled the air above where I had left the carcass of their comrade. They swooped and cried for about 20 minutes, letting us know that they had noted what we had done. I fully expected to wake up that night with our bed surrounded by ravens seeking retribution. But, that's just me and my unscientific fascination with this particular species.

    The pictures seem to be links that go nowhere?

  4. I'd be really impressed to see one of them pinching open one of those blue clothespins to use it to hold the nest together!
