Kinglets and More Nest-building

Mallards

Magpie at Nest

Western Scrub Jay

Hoping to see new migrants at Red Butte today, but nothing unusual. Birds have paired-up and heard or saw Mallards, Spotted Towhee, California Quail, Western Scrub-jay, Black-capped Chickadees, Magpies and Ruby-crowned Kinglets in close proximity. The grounds contained a number of singing Song Sparrows, but not sure they had found mates. Magpies were busy working on the next near the entrance, but they seemed somewhat annoyed by my presence.

The placement of twigs and size on this artificial nesting platform seems to be that of a Corvid. The Magpie duo which was building the nest near the garden entrance flew up that way, but I didn't seem them near the nest.
