Flicker video

Here's a video of our release of two of the fledgling flickers from the weekend. Let it be said that all of their feathers were still growing in...

Western Scrubjay

We caught this Western scrubjay on our closing net run today. They general stay above the nets, and are pretty smart, so we don't catch many. Scrubjays are one of the study species here at Palo, so in addition to the usual silver band with a number on it, we fashioned it with some color bands, allowing the nest searchers/finders/gridders to identify the individual again, without having to recapture it.

With a couple of the color banded species we have to use pyropens to melt the plastic bands together so that the birds cannot pick them off with their strong bills

This bird was just beginning to go through its prebasic molt (the yearly replacement of feathers) and may be the first adult bird we've seen in this process this year...

Hatch year flickers

Most of the birds that we are catching these days are hatch year birds, which means they were born within the last couple of months or so. Yesterday we got our first juvenile northern flicker, and today we've gotten three more, all from the same two nets, and all males.

The red mustache stripe tells you its a male

On this one you can see a white tip to the bill, something that we saw on two of the four, but did not notice on the others

Some of these young flickers can have a reddish wash to their crowns, something you will not see in adults
Photobucket

One of the most obvious traits of a very young bird is that every feather on its body is still growing in, like these tail feathers

This guy flew off, only to perch between two nets on this tree. He's still there right now, but I bet we find him in a net again soon.

New camera comes tomorrow, they say.

Finally got a chance to take a hike around some of the favored trails around the area, in the "water district."

Bad picture of yesterday's great egret rookery visit. About 60 pairs I think, nesting in a redwood. Got to see eggs, fresh nestlings, and some awkward tweeners.

Shocked

An Allen's hummingbird from yesterday that was a bit shocked by the banding processes, but flew off fine after a few shots of sugar water.

Good day banding at Lagunitas Creek. We caught over 20 birds, including a very stunning pair of Lazuli buntings.

Wood-Peewee

We've been catching more, I went to Oakland, H.P. Roberts graduated, I missed another cooper's hawk that was caught here, we recovered a 7th GLS tag from a Swainson's thrush, I order an SLR and...

...few days ago we caught a Western Wood-Pewee here at Palo, which does happen frequently in the fall, during migration, but isn't too common during the breeding season, as they do not breed right here.

Smaller than an olive-sided, larger than an empid, with nice long primaries

Spotted Owl Nestling

Yesterday Amanda, Todd and I went out with one of PRBO's biologists who does spotted owl surveys around Marin county. We went to a site where we hoped to find a pair and their fledgling. We spent two hours searching, only to find the youngster post giving up.

Here's the female doing some preening

Best day so far

Today Amanda and I had a really great day banding at Redwood Creek. We caught a total of 41 birds, with 16 species. The highlights were 2 barn swallows, a tree swallow, a black-headed grosbeak, a warbling vireo, and mix of juvenile birds! We also ran into a female common merganser with 4 chicks, shortly before peeking into the hummingbird nest I found the week before, which now has two cute little raisin-like nestlings in it.
