Wilson's Warbler Cardellina pusilla

Observer

Date

April 19, 2014

Description

7:30a.m. As soon as the Towhee was released, Beth began processing for the Wilson’s Warbler. He was relatively small with olive green on his wings, tail, and back and a bright yellow head and underside, all topped with black cap. Based on these plumage observations, we identified the bird as a male Wilson’s Warbler. By the time that Beth got to processing him, he had been bird bag for at least 20 minutes since being first bagged at the mist net site. I had carried him in the bag during this time and in the 20 minutes, his rate of fluttering around in the bag had decreased over time. When he was first bagged, he fluttered almost every six seconds. When the Towhee was being processed, he fluttered maybe once every ten seconds. When he was being measured and processed himself, he put up very little struggle and even allowed Tricia to hold him in the photographer’s pose. No wing chord and tail lengths were taken since we didn’t have the tools of the right scale to take accurate measurements for a bird of his small size. When it came time to releasing him, a flight path was cleared, a supine hand offered as a take-off point, and he was released right above the take-off point. He quickly flew off into a clump of bushy trees.

Not really sure if the ID can be resolved here, but whatever, this was a pretty neat find. This tiny fish was about 1 cm and found swimming in a very warm, very shallow puddle in a road rut that was filling with water at high tide. Not a sanddab, as I'd first guessed, since that's a lefteye flounder and this is clearly a righteye.

Description

We saw hundreds if not thousands of these in a road rut serving as a high intertidal mud puddle. Light's Manual says, "Populations in the San Francisco Bay are endangered; they now live in high intertidal marshes, having been displaced by Ilyanassa obsoleta." Similarly Cohen and Carlton (1995) write, "The introduced Atlantic snail Ilyanassa obsoleta now occupies the Bay mudflat areas formerly occupied by the native snail Cerithidea californica. Each spring the two populations of these snails collide, and by mid-summer the exotic Ilyanassa restricts the native Cerithidea to high-marsh salt pannes (an environment too high in salinity for Ilyanassa and thus providing a habitat refuge for Cerithidea) through egg-string predation and direct competitive interference." This population seemed to be booming, but as they described, it was right a the high tide line, and the pool was very warm and probably very salty.

There was a bunch of eelgrass washed up on the beach, almost certainly from the bed on the north side of the highway right where the Bay Bridge meets land. You can actually see the bed in the 2014 Google Maps imagery. There's also a good map in this 2004 eelgrass inventory by CalTrans and NOAA.

Description

These two guys were fishing out at the end of the radio road, and they had a cooler full of leopard sharks. The chatty one said they ate them, but that cleaning them was a pain, involving boiling off the skin, thinly filleting the flesh, and grilling it with butter. He said he didn't know how to do it, but his parents did. He also said they eat bat rays, even though most people through them back. He said people also catch 7- or 9-gilled shark there (he couldn't remember which), and that fishermen didn't like them b/c they were mean.
