TROCHET, JOHN 1991 Lesser Goldfinch Carduelis psaltria Bld land along Cut Creek, 1 mile E. of Clear Ranch adjacent to Quarry section of Dinosaur National Monument, Uinta Co., Utah. Elevation 5000 ft. June 16 At 18:09 I was about to shoot an apparent green-backed male sitting on a wire 20 feet above the ground when another male goldfinch came out of the field directly underneath the bird perched on the wire. This second bird few past me to the riparian zone along Cut Creek 30 yards to the south. I turned towards to see the bird on the wire drop into a scraggly, 4' tall grassweed plant, one of five grassweeds standing well above the grey-green, 8-12" pretty unknown (texas) species of bush. At, try, emerged from the site (maybe 12-15 seconds after landing there) and flew to the riparian zone. I walked to the grassweed and found the female sitting (closely) on her nest, not fleeing in front, until I was 2-3 inches from touching her. The nest was in the densest clump of leaves on the plant, six inches from its top. The three eggs were all ovaloid eggs. I positioned a mist net near the nest. At 18:50 the first males returned to the sitting and having fewed forward with the other male on the wire above, he flew out away from the nest and was not captured. He appeared to be sleek-backed. The green-backed one dropped to the nest briefly and also flew out away from the net (which was positioned between two nearby Cut Creek). I walked to the opposite side of the nest where I might place the bird into the net. At 19:11, the males few back together and landed on the wire. The sleek-backed bird dropped down to the nest after a wait of about 45 seconds. I changed the net and fewed the male into the net. The green backed one still sat on the wire, and the female still on the nest. After I retreated to cover 25 yards away, the green-backed one few down from its perch directly into the mist net. I succeeded in netting the female as well. I have found only 2 nests here - both attended by 2 adults (6) & / /. In both nests the sleek-backed one took precedence at the nest. I am also aware of any literature including lesser goldfinch away
