Summit, July 1917. Saw Williamson Sapsucker, Black-headed Grosbeak, and a Pine Grosbeak which was singing. Heard Nuthatch, Hermit Thrush. Thunder shower circled about us in late afternoon: Flock of birds feeding in Tamaracks across stream from camp - Fly high in flock, calling constantly "Keep, keep, Keep, Keep". Light in tops of trees, become silent as they fall to work. Balance themselves on ends of branches, sometimes hanging upside down, extract seeds (apparently) from cone, and fly with it to stronger branch where they get out the kernel, dropping husks to ground. After a few minutes they begin to call and fly to another tree near by or take their departure - Color largely red, - I suspect they are Crossbills. Aug. 2. Flock of 20 Crossbills (?) flew over, calling. Calls answered by others feeding in trees near camp - Aug. 3. Little Brown Creeper visited camp & sang at dawn. Next up to hotel at 7 A.M. for breakfast. Many birds fleeting.
