I have been under the gun with deadlines for papers so I have not got these out lately in a timely fashion. I will try to do better. I will, however, be brief in this report.

It was a pleasant day but not many birds. We got 13 species. See the two plots at http://birdwalks.caltech.edu/bird_data/two_plots.htm.

Note the latest Caltech News has a nice collage of birds on the back cover and a caption too. It's very nicely done. Thanks to Barbara Ellis for the advertisement of our bird walks.

Next week will be the last walk for Brendan Crill for a while. He will be taking a faculty position in Toronto.

The stats:
The date: 5/29/07
The week number: 22
The walk number: 885
The weather: 70F, partly cloudy
The walkers: Alan Cummings, Glenn Hamell, Beth Moore

Hi, Alan -

Here are my notes from yesterday's walk:

68 degrees, mostly overcast, some sun peaking through occasionally. We saw 18 species.

We had a pleasant walk that provided as many chuckles as birds. Perhaps we need to have an *Out-Takes* section of our report to handle such things as Barbara telling us to look in "the green tree" for a bird, Beth finding what turned out to be a crack pipe outside of IPAC and everyone wondering which bird had used it, and Glenn asking what type of bird the shiny-scalped workman on the roof of a building was to which Beth replied, "A bald eagle, of course!" In Barbara's defense she was directing us away from the purple Jacaranda tree. And if you're really curious, we decided it must be the ravens, as aggressive as they were showing themselves to be each time we spied one on the walk, that must have made use of the glass pipe.

We saw all of our regulars and many White-throated Swift.

It was a pleasant walk on Ditch Day at Caltech. So, in addition to the birds we observed a number of "stacks" that looked interesting. For a report on this year's Ditch Day see http://www.pasadenastarnews.com/news/ci_5906176.

As for the birds, we saw 17 species. The record for week 20 is 22 in 2003. But 17 is above average for a week 20. See the two plots at http://birdwalks.caltech.edu/bird_data/two_plots.htm.

We had a surprisingly good walk considering the heat. It was 93F and sunny. We observed 19 species which was not a record for week 19. The record for week 19 is 26 seen in 2002. See the two plots at http://birdwalks.caltech.edu/bird_data/two_plots.htm.

However, it was a record in the category of walks taken when the temperature was above 90F. Previous record was 18, accomplished in 1991, 1992, and 1999.

We had a good turnout of walkers. Barbara Ellis came very late but by the time we finished, she had put in half an hour and I say that qualifies as participation. So, we had seven walkers for the day.

Among the highlights were the White-throated Swift, House Wren, Wilson's Warbler, Western Kingbird, Spotted Towhee, Lesser Goldfinch, and Black-chinned Hummingbird. The Ravens are on the nest in the nook on Parson's Gates above the President's Office. They quickly rebuilt the nest after the buildings and grounds people tore it out recently. For an interesting article about the intelligence of Ravens see http://www.spiegel.de/international/spiegel/0,1518,476266,00.html. Thanks to Beth Moore for alerting me to this article.
