songs of the Blackburnian, Black-throated Blue, and the 
Black-throated Green Warblers, while a few hundred feet 
below the Hermit was still in song and a little above us we 
could hear the wonderful music of the Olive-backed Thrush. 
On approaching the singing-tree we found the Bay-breast 
still present and singing from near its top. Watching him 
carefully, we noted that he frequently flew away towards 
some deciduous woodland near by, and once chased away 
another small bird from the vicinity of his singing-tree. 
The search for the female again began, by posting ourselves 
among the deciduous trees where they joined the spruces, 
and it was not long before we saw the male chase the female 
into a small spruce close by, where she was readily identi¬ 
fied. She had a very pretty way of standing facing and 
inspecting us, with her wings half spread and her body 
bent forward well below the horizontal. In a trice both 
birds disappeared, and the male was shortly heard singing 
again in his favorite tree. An hour afterwards we again 
located the female close by, industriously searching the 
branches of large yellow birches, from which she was gath¬ 
ering food. On two occasions she was seen with her mouth 
crowded with caterpillars, with which she flew away, and 
there is little doubt but that she took them to her young. 
Although we spent considerable time searching for the 
young birds, we were unable to find them. They were prob¬ 
ably perched near the tops of the tall spruces, where their 
feeble calls for food were inaudible. 
The following lines were taken from my notes made on 
our second visit: 
“On the same tall spruce where we identified the male 
Bay-breast on July 17, we again found him singing his 
high-pitched, simple song, which, on account of its sim¬ 
plicity, shortness, weakness and distance from the ground 
(60 feet) may easily be passed by unnoticed even by trained 
observers. It is noticeable that wfiien he sings from the 
midst of a high, thick spruce, particularly from the further 
side from us, his weak song nearly fades away. 
“He is more restless than when we were here nearly two 
weeks ago, and keeps making little journeys to the border
