Bird walk at Alviso marina

Where have all the birds gone?  Just a handful of Avocets, a scattered few ducks, two pairs of Canada Geese, and a dozen or so Black-necked Stilts were around on this sunny (finally) morning at the salt ponds that empty into the southern end of San Francisco Bay.

A beautiful morning for a bird walk, with lilac plants framing the salt ponds.

The ponds here are usually full of waders and ducks, but not today.

One-legged birds? Black-necked Stilts at rest

I must be desperate to take photos of something, if I’m shooting train pictures.

Kind of disappointing.

But we accidentally started a feud between a Marsh Wren and a Common Yellowthroat Warbler, which made the morning memorable.  After seeing a male Common Yellowthroat land nearby, we played his “wichety” song, and instead of the Yellowthroat popping into view, we made the local Marsh Wren mad enough to come scold us for several minutes.

This bright Common Yellowthroat male was the one we were after.

Marsh Wren

You wouldn’t think a Marsh Wren would respond so intensely to the call of another species…but this bird was quite vocal about defending his nest territory.

Whistles, chirps, rattles, and buzzes come out in a continuous stream to drive off the invaders.

You almost never get this bird in view because they hide down in the reeds, and blend into their habitat quite well. But he/she was mad!

  1. Alviso is where my ancestors’ foundry was. The building might still be there next door to Vahl’s on Edorado Street. My Pa has a few historic pictures of Alviso before the Marina silted in and became parkland where the birds live now.

  2. Love the angry bird sequence.

    Maybe the train was a Burlington Northern, think Ralph Budd. 🥴

    Love your posts.

    And you.
