On 6/22/11, JO and I checked out the progress of the tanoaks at El Corte de Madera. For this years’ study we will try to collect some pollinators for ID, not for quantity. I brought a 45ml plastic tube. I put it in a ziplock bag, but at some point it leaked. I didn’t collect anything since there weren’t any insects at the one tree we’ve had a lot of activity at later in the year.
It was pretty warm (forgot to look at the temp but weather.com TruPoint said 75–may have been higher).
There was one tree to the left from the entrance (Gordon Mill) that had new foliage, and to the right one with catkins at the top (way up). We don’t remember if there was a dead one to the right last time, down near the tree that we observed the most before, but there is now. And that tree that we observed the most last time, about a mile in before a small meadow, has a few dead leaves, and had no obvious insect visitors. It was mostly shaded around 2:00.There are old dark brown catkins, and some green female flowers around .25″ and larger, and I think there are a few catkins at the top.
Birds calling: Hutton’s Vireo, Dark-eyed Junco, Black-throated Gray Warbler (I think), Wilson’s Warbler, Spotted Towhee, Brown Creeper, Chestnut-backed Chickadee, Steller’s Jay, Warbling Vireo, Band-tailed Pigeon, and a distant thrush.
Insects out: lots of spiders, some bees, flies, beetles, grasshoppers, and a few butterflies and dragonflies flying around.
We saw two garter snakes. One was dark gray with a yellow stripe and slithered into the grass before I could get a photo, and the other was more colorful. It slid into an insect net by itself. After taking some photos for ID, we quickly let it go.
Here are photos. The tanoaks are first, then insects and other things.
