Walk lasted between 12:00 and 13:45

We had two new walkers join today, Wan-Ying Kan and her son Calvin Kan. They are the 233^rd and 234th individuals

to walk the Caltech bird walk. Wan-Ying’s husband works on campus in the Liquid Sunlight Alliance group. Welcome Wan-Ying and Calvin!

We observed 18 species, which was 1.1 above the prediction, so it was a good walk. We saw the same species

set as last week, except we saw Band-tailed Pigeon and Red-masked Parakeet, instead of the swifts and swallows of last week.

I solved the number of walks problem that I presented to John at the corner of Wilson and California. I thought 1826 walks

didn’t make sense, since I thought I’d only been doing this once-a-week walk for 29 years. But my 3rd grad math was off: it’s actually been about 39 years.

First walk was 10/15/1986. Wow!

Alan,
