[cobirds] Blue-winged Warbler, Cottonwood Marsh, Walden Ponds, Boulder County

CObirders,

At dawn this morning, I heard the familiar "Zee-zee" (going down in pitch) as I was leaving the Walden parking lot with the bass fishermen!  This is one warbler song I will never forget, having grown up in southern Ohio.

There was a small flock (<12) of "eastern" warblers that flew by me in the darkness before dawn.  It was cloudy and fairly warm; clouds of insects could be seen over the water.

Many birds (i.e. Yellowthroat, Bullock's Oriole, Yellow Warbler, Warbling Vireo) seem finally to have returned.  I've been sick and not doing any birding for a week.
