Low lying fog and clouds in the surrounding area curtailed migrating birds from dropping into the banding station olive grove this morning. There have been a couple accipiter hawks around the area all week. We caught another male immature Sharp-shinned Hawk today. otherwise a slow and quiet bird day. Fortunately we had a couple birds to show and talk about bird migration to Gold Camp 5th graders this morning.
A Hammond's Flycatcher was hanging out in the cottonwoods singing this morning. What a loud singer for such a little bird!

The Ranch received some nice rain early in the morning. It basically
stopped before we opened the nets-thankfully. Wilson's Warblers were
chipping most of the morning while searching for insects. Sixteen bird
species were captured today with a highlight of an adult male Western
Tanager and a Clay-colored Sparrow. Those sparrows are very beautiful. A
birder saw a Townsend's Warbler around the banding station- a bit late for
them but seems there are more around the area this fall.
