Last evening about 5:15-5:45 PM, a lone gnatcatcher was calling and foraging in the trees along the west-norhwest side of the lake and into Greenlee Preserve where a pair of Swainson’s Hawks was sitting together in a tree. Yellow-rumpled were the only warblers seen and heard.
Avocets, gadwalls, and a pair of blue-winged teal were among the birds in the low water in Greenlee Preserve.
Overhead were barn, cliff, and tree swallows and a frantic killdeer.
