Nick Belardes, Torrey Gage-Tomlinson and I arrived while it was still foggy at the Norswing/Coolidge corner entrance to Oceano Campground at 10am. We were immediately impressed with the numbers of warblers. Even with three of us looking and shouting out names, we could not keep up with them all!

Townsend's Warbler was the most common (18), yet Black-throated Gray Warblers (8) were everywhere - and I bet we underestimated considerably. The swarm of warblers followed us for a while, then we found ourselves in large, mixed flocks three other times in our three-hour extended loop, where we met several other local birders out enjoying the morning.

All told we saw TWELVE different warblers, and missed Blackpoll and Tennessee Warblers seen by others.

Quite a day at Oceano Campground. Migration continues.
