More details on the Chestnut-Sided Warbler at Fort Mason


David Assmann
 

The CHESTNUT-SIDED WARBLER seen at Fort Mason this morning was an adult male in alternate plumage.  It was first heard singing in a tree on the west side of the garden and then moved to the north side of the garden, first in the plum trees, where it was seen from outside the fence, and then into the avocado tree, before heading to the east side of the garden.  Because the garden is still closed to the public, this bird is hard to photograph. A BULLOCK'S ORIOLE was also seen on the west side of the garden, and a YELLOW WARBLER was behind the General's House.
