After two years of 100% mortality rate at fledging, the San Francisco peregrine falcon nest has two young males getting good at this flying thing, one female starting to get the idea, and the second female–Amelia (see her fledge starting at 7:29), who had seemed reluctant to go out there, I’m sorry to say didn’t survive today’s attempts.

In the busy middle of downtown, volunteers were trying to follow the birds’ movements to protect the little ones. They take off not only before their flight feathers are fully in, but the feather shafts are still full of blood for that growth, adding weight for extra clumsiness. They have to learn to land with wings as well as with the feet that have been all they’ve really manuevered around the ground with before then.

One male found himself sliding sideways backwards and about to fall off a skyscraper, when his mother came zooming in and body-checked him back up into the gutter where he had a chance to straighten out and fly right. And after catching his breath, he did. Thanks Mom! That was on Mother’s Day.

While the parents kept close watch but were being outnumbered, each of the four eyases took a turn at being rescued: put in a box, taken up in the elevator to the nestbox on the 33d floor of PG&E, doused with water to slow their heart rates and calm them down, and given a second chance.

Here and here are Perry a few days ago, the first to try: he chipped his beak hitting a building and was on the ground stunned, but now he is enjoying this whole airborne idea. And beaks grow like fingernails.

Last year that nest and the San Jose one were in sync, but this year ours was delayed a week by males fighting for Clara and territory. The eggs sat there waiting, which is fine, and incubation only began after things were decided and the new male had taken over. The count to hatching starts not from laying but from when the parents start keeping them warm.

So our fledge watch is about to begin. The males, who being smaller don’t have to put as much time into growing, tend to go first, and ours are getting antsy to try.

And I have old falcon friends to see, too. Friday evening I’ll be there!
