Outside the Western Foundation of Vertebrate Zoology, a Great Horned Owl had attempted to find some shelter in a sycamore tree from a small murder of crows that had been harassing it. The owl did not vocalize and only surveyed its surroundings, after the murder had left. It eventually left some time later in the afternoon.

j_mcgowanDescripción
A hatch-year juvenile Red-tailed Hawk that was chased into the side of a nearby building by a flock of crows a couple of hours earlier. He/she was initially unconscious after the collision, and local museum staff had moved to a protected area of a canopied table nearby. The hawk has since regained consciousness, but is still recovering from what appears to be head trauma, and may require a couple hours more, before being able to take flight again.

j_mcgowanDescripción
A couple of shots of what turned out to be 5 juvenile Cooper's Hawks that were grouped together around a suburban neighborhood at around 7 AM. They were frequently flying in loops from one tree to another, with at least one other juvenile ate a time, and wer frequently making their cry-like juvenile calls. It was difficult to photograph them, since the tree they appeared to favor was a densely leaved eucalyptus, likely for concealment from nearby crows and western gulls.
The ones photographed here were perched in a jacaranda tree, before joining the other 3 in the eucalyptus. The skies were clear, with a very faint breeze, and temperatures nearly 70 degrees.

Sadly, the best photo I managed to get of a small flock of American Goldfinches I heard and observed in the trees around the visitor center during a chilly morning, with a low overcast (which this finch is back-lit against). I was able to identify them by their distinct calls as American Goldfinches.

Around 3 pm of an 85 degree afternoon, encountered what I believe to have been a Blue Grosbeak perched in one of the trees that line the creek bed along the main trail, between the parking lot and culture center. It gave a few, brief calls, and glanced down at me, as I took photos of it.
