J Groth 1986 journal 99. 1 mi. N Tennessee Pass elev. 10,400 ft. Eagle Co., Colorado 1 June I chose to camp on the S end of a clearing (pine/spruce savanna habitat) just above a stream. No crossbills were heard that evening. 2 June At dawn a lone type 5 crossbill visited the camp, but showed little interest in the two type 2 decoys (#'s 387 & 390). Later, another type 5 bird came on the scene, and I got recordings including loops -- then made a playback loop on cassette using this material. When a lone type 5 male came around later, I used this loop and caught the male. Later, I prepared bird 390 as a specimen. By noon it was blowing and rainy so I decided to dismantle the net and move on. Just before I left the area, a pair of type 5 birds arrived on the scene. As I scrambled to set up the net, they flew on. This locality was of lodgepole pine/ spruce forest, with old dry cones on many of the mature spruces and a very good crop of lodgepole cones.
