Notes from Colton, California
A set of eggs of the Ash-throated Flycatcher (dlyiarchus cinerascens cinerascens) was collected near here in May, 1918. The nest was in a cavity in a dead stump and was twenty-two inches below the opening. While I was removing the nest material I was surprised to feel more eggs under the flycatcher's nest. These were eggs of the Red-shafted Flicker and all but one had holes in them. Possibly the flycatchers had driven the flickers out of the cavity, pecked holes in the fresh flicker eggs, and had then gone on with their nest building over the ruin.
May 7, 1918, I collected near here a nest of the Tree Swallow (Iridoprocne bicolor) containing three eggs of the swallow and one egg of the Western House Wren (Troglodytes aedon parkmani). The wren egg could not have been placed in the nest by a boy, as a section of the tree had to be removed before the nest could be examined. I observed the swallows taking feathers to the nest at least ten days before I collected the set. I did not see any wren nearby.
A set of four eggs of the California Yellow Warbler (Dendroica aestiva brewsteri) was taken by me near San Bernardino on May 5, 1918. Elevation above sea level was about 1000 feet. I consider this a very early record for this species.
