|Can't see the birds for the trees...|
There is actually plenty of activity - house sparrows and house finches are all over the place, mainly foraging for invertebrates in the oaks.
Violet-green and barn swallows are equally busy, as are the downy woodpeckers. Some bushtits have already fledged, and family groups can be heard pinging in the undergrowth.
Meanwhile, the Cooper's hawks seem to be keeping a low profile, though I imagine it's more a case of them being less visible in the heavily leafed trees. There are two active nests, one with an adult female the other with a sub-adult female (banded - red darvic on left leg, metal ring on the right). I suspect there is just one, polygamous, male but I can't be 100% sure.
The highlights of a wander down there yesterday evening included 4 flyover Caspian terns and the first chipping sparrow that I have seen on the site.
