This morning at Mt. Davidson I observed a singing 1st-spring male American Redstart between 7:30 and 8:00. I first heard it from the Ravine and subsequently located it in the eucalyptus canopy as it worked its way west into the eucalyptus forest. Last observed it around 8:00 in the area of the Bowl (i.e., the open area within the forest)..
Also in the Ravine was a Willow Flycatcher which gave its "whit" call a couple of times and briefly skirmished with the Western Wood-Pewee that is still hanging around. A calling pair of Ash-throated Flycatchers put in a brief appearance in the eucalyptus canopy on the north side of the Ravine, and a singing Black-headed Grosbeak continued in the same area.
