Ahhh... week 26. Half way through the year. Walk number 789 -- on our way to 1000. Should get there in about 4 years.

The walk was distinguished by a Lesser Goldfinch. This goldfinch came undulating over towards us in the maintenance yard. It was sounding very weird and at first I thought it was a woodpecker. But no, one lonely, squawking Lesser Goldfinch landed in a tree 20 feet away. That's our highlight. That and the Cooper's Hawk. By the way, I changed the Sharp-shinned we saw last week into a Cooper's after an email from Jon who said it was very unlikely to be a Sharp-shinned this time of year in Southern California. I then reviewed the bird books and discovered that Cooper's can be pretty small, 14", not that much larger than a Scrub Jay (11"). So, I agree, it was a Cooper's Hawk. We saw one flying this week.

We saw 11 species, towards the bottom end of what you'd expect for the end of June. See the birds_epoch plot at http://birdwalks.caltech.edu/bird_data/two_plots.htm. Pretty pleasant walk for this time of year -- sunny and only 77 F.

No report last week, in case you are keeping track, since no one could do the walk. Today was a beautiful day, although it was a tad on the hot side. It was about 85F and sunny.

We saw 14 species, not a record for week 25 of the year, but not bad. The record was set last year with 19. But 14 is above average. See the birds_epoch plot at http://birdwalks.caltech.edu/bird_data/two_plots.htm.

We did have a great highlight. We saw a Sharp-shinned Hawk close up and personal. It landed in a tree and hung around for several minutes not 10 feet from our noses. The tree was full of Bushtits, which may be why he landed there, but we didn't see him try for one. They wouldn't be much of a snack. Pretty bony I imagine. Best look at the Sharp-shinned I ever had.

And suddenly it happened. Well, nothing really happened all that suddenly, but I've always wanted to start a story that way.

Not too much happened, actually. It was a beautiful day, about 73 F and just a little breezy and clear as a bell. Kent said it's tough to have to live in Southern California. We only recorded 11 species, not too good; in fact we tied for worst ever for week 23. See the birds_epoch plot at http://birdwalks.caltech.edu/bird_data/two_plots.htm.

We could have saved oureslves from that distinction if we had seen a Scrub Jay, which is supposed to be 100% probable this time of year. See the probability plots at http://birdwalks.caltech.edu/bird_data/probability_plots.htm.
