Podrobnosti k pozorování
I found this calling bird at ~8:45 AM as it foraged in an ash tree at the west-end large, open lawn. It flew off to a nearby ash, where it stayed for several seconds, and then returned to the first ash where it repeated this action several times. The second ash, at 34.019845, -118.364205, has a small cavity ~20 ft up on the southern side of the tree (new tag #523) where a limb was sawed off several years ago, and the WBNU entered this cavity with plant material in its beak - see photos. This bird also briefly foraged on the ground, and I lost track of it at ~9:07 AM. I last saw two WBNH simultaneously at VG last spring & summer, when a pair of birds fledged at least 3 young, so I do not know the current status of this year's nesting activity. There may be two adults at VG now, or perhaps a single bird was induced by hormones to construct a nest in hopes of attracting a mate. The Birders Handbook says both female & male WBNH may construct nests. According to the Los Angeles County Breeding Bird Atlas, details about local WBNU nesting sites are fairly sparse.
