[SBB] Feeding spectacle at Alviso EEC

Amazing sight this evening on salt pond A16, probably already witnessed by some. I walked up to the pond around 6:15. Two days of high winds out of the W-NW have pushed most of the algae into the SE corner of the pond, creating a mat at least an acre in size and sturdy enough to support all but the larger birds. It was reminiscent of an avocado shag rug out of the seventies. Yuck. It was swarming with Black-necked Stilts and Forster's Terns. Among them were the Black Tern and a few Bonaparte's Gulls. Also there were a handful of dowitchers, Greater Yellowlegs, Least Sandpipers, and Snowy Egrets. Only a few Western Sandpipers and one Great Egret. In total there were hundreds of birds on the mat. The Black Tern was hanging in the wind often near the levee, while the Bonaparte's Gulls chose to walk on the mat. The Black Skimmers had their privacy invaded by hordes of terns and gulls roosting on the island. Yesterday evening the mat was actually larger but very few birds were on it. It appears to have been compressed over the last day.
