I have spent the last 3 days working my block in the Santa Cruz Mts, just off Hwy 17 and west of it. All the rain seems to have fueled a bountiful year.
There are baby Orange-crowned Warblers everywhere. Yesterday I had a remarkable experience near the intersection of Bear Creek Rd and Skyline Blvd; It seemed like a Bushtit flock was moving through. I got my glass on one and it was a young Orange-crown; then another, then another, then another. It was a flock of them: rather Bushtit-like in spacing, movement and even the sounds they were making. But every one was an Orange-crown. At least 10 of them. I have seen post-breeding flocks of Orange-crowns in the Sierras, but nothing like this near the coast. Today I returned to the area and everywhere I went, family groups of Orange-crowns. And quite a bit of singing as well, which I think indicates double-brooking. In dryer years they seems to be far less vocal (inclined to sing) by June.
