Parus rufescens
No. 27— Jewell L., Tilden Park, Contra Costa Co., NE of
Berkeley, Calif. one heard, and finally
seen well enough to see lead patches of dark
& white, in willows just S. of pond.
Dec. 5 one heard calling “zw-eep” repeatedly
from near the same spot as above. Dr.
Miller called it down close, by imitating
its notes & “squeaking,” to where all of
us had a good view of it from all sides.
