1. Groth 1986 journal 134. wrapped up the net. Other birds were Clark's nutcracker, (scarse), flocks of juvenile chipping sparrows [no! adults seen!], cassin's finch, pine rishins (uncommon) robin, audubon's wambler, evening grosbeak (uncommon), western tanager. Aug 5 More netting of crossbills today. Almost all birds in groups of Type 2's. A flock of four type 4's were seen today. No type 5's heard today. I estimate that I encountered about 100 birds, almost all Type 2 juveniles. No adult ?'s seen, and only rare full adult ?? No singing was heard. Birds appeared to forage actively on lodgepole pine. Flocks sometimes moved very low to the ground. No groups over 10 in size were seen today, few birds were alone. I saw gray jay ad pine grosbeak in camp today, both as pairs of what looked like young birds.
