H.W. Grinnell-1925 mineral, 4800 ft July 19 Chickadees sing every day and, at any time and in any direction, wherever one may be. A walk thru the brush anywhere draws down upon one much adverse criticism, for altho birds are not singing much they are by no means voiceless and are still caring for young not long out of the nest. Yesterday when scolded by an adult tobyie warbler I "squaked" out of the nearby thicket two young not long out of the nest. This mon- ing the solicitude of a Wright (?) fly catcher attracted my attention to a youngster in a ceonothus brush hardly able to fly. We hear the grouse "bount" as often as we did in June. 5:30 P.M. We have just been down to the chipping-sparrow nest found this morning. There are now three young and one egg.
