Yesterday, May 31, I checked on the yellow-throated vireo nest that Pete K. and I found on May 4 at the sycamore picnic area within Miami-whitewater park in Hamilton county. On May 4th it was in the building stage. Yesterday I discovered two nestlings begging (a behavior seemingly stimulated by the slightest breeze which causes the drooping branch containing the nest to sway) for food but no parents seen nor heard within the 35 minutes I watched (7:30-8:05 a.m.). The nestlings' eyes were still closed and they had white down on their crowns. Yellow mouth linings assured me these were vireo nestlings and not cowbird nestlings (cowbird nestlings would show red mouth linings). It was surprising that I did not see any cowbirds in this nest despite a pair foraging nearby on the lawn. The vireo nest is approx. 12-15 ft. high suspended from the fork of a tulip poplar. The nestlings appeared to be healthy so I am sure that the parents were somewhere in the vicinity. Other birds using the tree included male orchard and Baltimore orioles, six cedar waxwings, red-bellied woodpecker and American goldfinch. Red-eyed and warbling vireos heard singing nearby as well as Northern parula and yellow-throated warbler. -- David A.
