Birders:

Well, the weather was nice, the company was good, but the birds were mostly in hiding. Kent, Bill, Glenn and I were joined by my niece Kelly Jung. Kelly works in the Grad Office. She has volunteered to make a webpage for the group. She seems to attract Bant-tailed Pigeons. We saw more of those today than we've seen in a long time. The highlight bird was a Cooper's Hawk. I think
this bird was going down as a Merlin but as I was flipping to the Merlin page, Kelly noticed a bird one page back. She said go back a page and there was a picture of a Cooper's Hawk that looked
exactly like what were seeing on the top of a tall tree on Wilson. So, thanks to Kelly for keeping us on the right track with that one.

(Jon Feenstra emailed in Yellow-chevroned Parakeets he saw over lunch).

Birders:

What a fine day it was! Temperature was about 74 F, partly cloudy. Walkers were Alan, Glenn, and Kent. Digging in the North athletic field for the new parking structure has begun in a major way and it was so dusty that way and so unlikey that any bird with a decent-sized brain would be over there that we skipped looking over the field.

We saw 20 for the day, not bad. Looks like the expected range for mid-February is 15-28 and 20 might be about average. I suppose the highlight bird was a Nuttal's Woodpecker, observed
briefly along Wilson. The Bewick's Wren placed second in the running for highlight bird.

The list:

Rock Dove Scrub Jay Mockingbird
House Sparrow Mourning Dove House Finch
Anna's Hummingbird Acorn Woodpecker Crow
Starling Yellow-rumped Warbler American Goldfinch
Lesser Goldfinch Bushtit Bewick's Wren
Gull Black Phoebe Nuttal's Woodpecker
Yellow-chevroned Parakeet Band-tailed Pigeon

Dear Caltech Birdwalkers:

Today's walk was very interesting. We saw 20 species, which is about typical for this time of year. But we saw 3 huge flocks of Cedar Waxwings and also a lot of Anna's Hummingbirds and House Finches. A flurry of birds accosted us on Holliston towards the end of the walk, including White-throated Swifts, Yellow-chevroned Parakeets, one of which was perched at the top of leafless tree as if it were a flycatcher, a bevy of Band-tailed Pigeons, 3 of which were swallowed up in a giant flock of Cedar Waxwings, so much so that Kent and I worried for their safety, a Black Phobe which was hotly pursued by a hummingbird, and a couple of American Goldfinches. Despite valiant efforts on everyone's part, no House Sparrow was seen. While I don't mind a decline of House Sparrows, I do object to their total absence, as it hurts the total count. Couldn't just one hang around Chandler at all times?

The walkers were Alan, Glenn, Kelly, and Kent.
Temperature about 60 F, cloudy.

The birds:

Rock Dove Scrub Jay Mockingbird
Mourning Dove House Finch Anna's Hummingbird
Acorn Woodpecker Crow Cedar Waxwing
Gull Ruby-crowned Kinglet Turkey Vulture
White-crowned Sparrow Robin Yellow-rumped Warbler
Band-tailed Pigeon White-throated Swift Yellow-chevroned Parakeet
Black Phoebe

American Goldfinch

 

Your reporter,
Alan

I had lunch at the Ath today with a visiting prof but I kept my ears open on
the walk there and back. I got your House Sparrow as well as Bushtits.

I'm glad you got Robins. I heard a bunch of them flying over this morning
and was hoping a few would stick around to lunch time.
