A nesting american avocet peeks above the pickle weed
This american avocet was sitting on her nest, hidden in pickle weed along the bank of a shallow slough. Avocet nests are fairly unimpressive – they are usually just a small scrape along the ground, sometimes lined with grass. Sometime avocet females will lay their eggs in other avocet nests – or even the nests of other species. Likewise, other species (usually black-necked stilts) have been known to lay their eggs in active avocet nests. The avocet female that tends the nest will raise the stilt chicks as if they were her own.
In taking this week’s photo, I had the opportunity to watch up close a willet’s feeding behavior when one opened a mollusk (probably a mussel) and pulled it out of its shell.
It started by moving to a likely area of shallow mud at the edge of a slough. Using its beak to poke repeatedly into the mud, it soon hit the hard shell and pulled the mollusk free. Then, it slipped the tip of its beak into the opening of the shell, and began to pry it open. Once it had a large enough opening, it was able to reach inside and grab the creature, shaking it back and forth through the water, most likely to clean it off, and shake it free of the shell. This process went on for a couple of minutes, the willet slowly extracting more and more of the mollusk from its shell. Finally, it was pulled free and vanished down the bird’s throat. Satisfied, the willet stalked off in search of other prey.
A white-faced ibis stops searching for food briefly as it soaks in the last rays of daylight
A few weeks ago I was at Baylands in Palo Alto, photographing at sunset. I was hoping to catch a glimpse of a white-faced ibis, which I had seen several weeks before, but only briefly. This bird is a rarity in the area, and seldom emerges from the pickleweed, choosing to hide in the wetland vegetation. However, a pair have been spotted in the Palo Alto and Mountain View area more regularly since January of this year, and up to three have been seen intermittently over the last few years. Whether this is a migratory aberration, or more likely a few year-round rogues, it is exciting to see one up close.

This specimen does not follow the normal head plumage that give the white-faced ibis its name, but is an alternate of the same species. Its iridescent bronze-brown feathers glow in the sunlight. I was very lucky on this day to see the ibis out in the open, fishing along a slough just as the sun was setting behind me.
I almost missed it however – as I was packing up my gear for the day, I saw another photographer with a large lens speed-walking toward a slough with open views. I hoped that the thing that had caused this rare burst of speed was the very bird I was looking for. I decided the effort was worth the chance, and unpacked my gear to follow him. I was happily rewarded when I saw the ibis poking through the mud, in gorgeous evening light. I had about five minutes with the bird before it was spooked by passerby’s and flew off for the day.

A long-billed curlew snaps at a gull, chasing it away
Most of the time, many different avian species coexist in relative harmony, going about their business while generally ignoring one another. However, as this week’s photo can attest, there is occasionally some friction. I’m not sure what caused this curlew to snap at the gull, but there was quite a flurry of activity before the gull was chased off. It wasn’t until I reviewed the photos later that I saw the curlew defending his territory.
