Apr.18 (contini). Near the Foresting experimantal plot I heard a strange note which I could not identify -57 a short song; loud, clear, short. Did not see the bird. Apr.19.

A group of 12-15 Pileolated Warblers was seen, staying close together in the willows and Baccharis near the trail and one Russel-backed Thrush was calling and singing near where I left the car. The trees are being sprayed near the Botanical gardens.

I sat down on the pier and after a few minutes they slipped back to the same spot. Afterward the male went into the street where he either stood perfectly still or ran rapidly a little way. After fifteen minutes or so the female joined him and they both went up to the end of the road where they dis- appears.
