观察细节
Nest 10m up in a bending cottonwood of about 20-25 cm DBH, atop a small branch just a few cm off the main trunk, at the edge of cottonwood forest looking out over young trees lining the river. Female was visiting nest with spider webbing and shaping it by sitting in it. Nest appeared nearly complete. See photos. ... 5 of 7 birds (and all 3 males) were along a stretch of trail with many blooming Mahonia plants.
