journal 1.6uth 3. 1984 Screhen Creek, California Oct 13 and found 4 crossbills (10♂, 3♀) in the net. 3 others were hanging around, one of these was soon captured, the next was shot by me at close range after recordings of vocalizations. The 3rd bird, a ♀, was recorded, then I shot and missed her at long range. Later, a flock arrived, and of this flock of about 12, 4 were captured (3♂, 1♀). We went to have lunch and got back, and a large flock of about 18-20 came from the N, and 11 of these were captured (6♂, 5♀), the rest flew off. All crossbills sounded like Type 2 so far today. We had a break at about 2:30, and got back to the net around 3:15. Two ♂'s were in the net, of unknown flock affiliation. Thus, 23 x-bills total for the day. Interesting that all the ♂'s were red, and no birds had any traces of juvencal plumage. The measurements correspond to the vocalizations: Type 2. Little
