June 20-21 Woolsey Canyon. -- Young of several species scattered through canyon and moving about irregularly: Downy Woodpecker, Plain Titmouse, Bewick Wren, Wren-tit, Song Sparrow; Brown Towhee, Spotted Towhee. It is impossible to make any more than a crude estimate of the increase in population in terms of the more prominent species. It is at least doubled, possibly tripled.
With the titmouse and downy, the increase is more striking when the nesting has been successful, since only one pair each was present.
Young Rufous-crowns, Chipping Sparrows and Oregon Juncos observed feeding together forming loose flocks in chaparral edges of the upper part of North Draw.
