About 50 AMERICAN CROWS mobbed a GREAT HORNED OWL this morning for at least an hour.  The owl didn't move, and the crows eventually stopped harassing it. Had my FOS FOX SPARROW (Battery) and SAY'S PHOEBE (Great Meadow).  1 BLACK-HEADED GROSBEAK, 18+ WESTERN TANAGERS, 1 WILSON'S WARBLER, 4 TOWNSEND'S WARBLERS, 14 YELLOW WARBLERS, 1 ORANGE-CROWNED WARBLER, 1 BULLOCK'S ORIOLE, 1 HOODED ORIOLE, 2 SAVANNAH SPARROWS, 1 HOUSE WREN, 1 RED-BREASTED NUTHATCH, 2 WILLOW FLYCATCHERS, 1 WANDERING TATTLER, and at least 5 PACIFIC-SLOPE (WESTERN) FLYCATCHERS.
