[EBB Sightings] Geese, very pale gull, and canvasbacks - Fremont environs

On a tip from Amy McDonald that 20 cackling geese had been seen at Lake Elizabeth in Fremont last week, I went over at noon to check it out.  On the lawn near New Marsh (northeast side of the lake) I found 79 Canada geese, 8 "minima" cackling geese, and 4 "Aleutian" cackling geese.  I also found 3 greater white-fronted geese.

With the geese was a very pale gull.  Its bill says "immature glaucous-winged", but its feathers are very light.  The bird was ill or injured or both.  Both heels looked unusually knobby/swollen, the bird lay on its breast on the grass, no other gulls were anywhere nearby, and the bird was clearly ADR (a wildlife hospital technical acronym for "Ain't doing right").  It could, however, fly away, as it did when two children and a dachsund dashed out into the middle of the flock. I had my back turned at that moment and didn't see it in flight.  I would love to hear if anyone has any other thoughts on the i.d. of this gull.

I tried to find the burrowing owl reported at Ohlone College's new Newark campus, but a 45-minute search yielded "only" western meadowlarks, red-winged blackbirds, mourning doves, and the like.

I drove out Marshlands Road at Don Edwards NWR as well.  Not more than a mile from the stop sign near the old visitor center parking lot, 33 canvasbacks were in the slough with the ruddy ducks near where the cormorants line up on the bank to sun themselves.

Painted lady butterflies (and probably other kinds) were everywhere, especially along the canal south of the Ohlone campus and even along the shoreline of the tidal ponds at Don Edwards.
