Chicks everywhere

It's definitely spring now! The air is filled with the cheeping of baby birds demanding feeding.

I thought we didn't have a nesting mockingbird pair this year, because there's been almost no singing. I've heard chicks cheeping from the yard across the street, but nothing in our yard.

Until today, that is. This morning, there's a mocker chick in the holly tree in the front yard and another one in the red oak in the back yard, both making noisy demands to be fed. The parents are having a hard time, between hunting and flying back and forth between the two chicks.

The chicks are staying too high up for any good photos, but they're easy to see in binoculars. They're a bit bigger than house sparrows, but still very baby-like, with short tails, fluffy spotted downy chests and big wide yellow bills. They can flutter from branch to branch pretty well, but aren't comfortable going farther than that, especially on this windy morning. I wonder if the wind explains how the two fledgelings ended up in trees so far apart?

(Update a couple of days later: turns out there are actually three chicks. One of them is confident enough to fly in the open and perch on power lines; the other two haven't moved from their respective trees.)

I'm hearing lots of California towhee pings, too (they make a noise like a submarine sonar ping) and there's a towhee pair foraging more actively than usual in the garden, so I'm pretty sure there are some towhee chicks somewhere nearby, getting ready to fledge.

After watching the fledgelings in the yard for a while, I decided to take a peek at some Peregrine falcon webcams. The IndyStar falcon-cam is easy -- two views to choose from, and it pops up a window with an image that refreshes every 30 seconds. Works everywhere. The San Jose falcon-cam is a lot trickier, since their page is loaded with elaborate "pop up the Microsoft Windows Media Player plug-in, and if you don't have that, you're out of luck" code. But Sarah and I and some folks in #linuxchix worked it out a few months ago before there was much to see: it's actually a Realplayer stream, which realplay itself can't play but vlc sometimes can: vlc rtsp://

It doesn't work every time -- I have to try it five or six times before I get anything. I'm told that this is a common problem -- RTSP streams are notorious for having problems with NAT, so if you're anywhere behind a firewall, keep cheeping with vlc and eventually the server will feed you some falcon images.
