I heard it, and saw it; I understand that this photograph might not be identifiable to species by itself.
The sign gave me a clue...
I am not sure if this is a first-year Red-crowned or a first-year Lilac-crowned. Didn't get to see the tail. The Lilac on the crown extends pretty far on the head, and can also be seen on the nape a bit.
Flock of at least six birds
This guy was truckin'! Desert scrub in oil country
Active ant hill in the oil lands - desert scrub - of the soithwestern Central Valley of California
Hardly "urbania" - this is an exit area off I-5 and SR198, but too funny not to include
This insect had bright orange wings when it flew. Large, maybe a bit bigger than common bumblebees. This is in desert scrub habitat. There were a few of them around. I have some additional pictures.
These plants were on a mass of exposed rocks in this lagoon area. They seemed dry and brittle, as if they'd been stranded above the water line for a long time
There was a pair that was probably looking for nest sites. I disturbed them, but for a good reason: a feral cat was in their neighborhood.
