juvenile mergansers, terns… and the taxonomy page

Filed under: birds,Photo — Supersonic Man @ 1:27 pm

Went to Rodeo Beach, and ran into something lucky at the lagoon there…

We thought they were a new bird we hadn’t seen before, but it turns out they’re juvenile common mergansers.  I’d seen the adults… but not since 2007.

Also managed to BIF some terns earlier yesterday, at the Berkeley marina…

I took the first one for a caspian tern, but it’s actually an elegant tern.  The second one is a forster’s.

At the end of the day, before returning home, we came back by the marina, and I managed to check the western sandpiper off the list.  Both westerns and leasts congregate there, and previously I’d only gotten clear shots of the least.  This isn’t a great shot, but it does clarify the species as western…

This brings my checklist up to 106 species.  My more informal home list, including non-photo IDs where I didn’t record the date and location, is at 123 species plus eleven possibles where the ID is not confident.

Over the last several days, I’ve made a new webpage which is an index of bird species by taxonomy.  It lists 239 bird species, this being the union of these three sets: (1) all birds I’ve IDed, (2) all birds listed on the’s bay area guide card, and (3) all birds listed by as normally seen in the areas of Berkeley or Lafayette.   Every bird I’ve photographed in the wild has a link to the best photo I’ve come up with — some have two links, for cases where there are significantly different plumages (juve vs adult or male vs female).  There are 103 photographed species.

The url of the taxonomy is:

  1. That page now has photo links for 187 species, but 10 of those are uncertain identifications and might not count.
