Vireo flavifrons. 
Concord, 
1895. 
May 30. 
Mass . 
For a weeh or more a Yellow-throated Vireo has sung in 
the early morning and at intervals through the day in the elms 
in front of the house. He seems to spend practically his en- 
tire time in these trees. Indeed I do not remember once hear- 
ing him elsewhere in the neighborhood, even the orchard. Tnio 
morning it occurred to me to loolc for the nest and almost at 
the first glance I discovered it suspended after the usual 
manner in the forh of a short branch that grew out from one of 
the big upright stems of the elm about 20 ft. above the ground. 
One of the Vireos, the female I thought, was on the nest. She 
sat rather high and Kept her head roiling and peering about 
in the manner of all Vireos. The male, if in the tree, was 
silent while I was watching this nest.
