resident as it was found nesting in April and May, but after May 
15, very much to my surprise, they disappeared completely and — 
were not again seen until after the first frosts of October. During 
_ the past season females were taken in Washington County from 
April 1 to 16, which either contained undeposited eggs in the ova- 
duct or showed by the bare and wrinkled condition of the breast 
that incubation had begun, proving conclusively that the species 
bred in this locality. My last specimen was taken on April 25, 
after which date they began to disappear as in former years and 
were all gone by May 15; although the deepest, darkest recesses 
of the forest were searched repeatedly for evidence of the species 
not one could be found; thickets that in March and April rang with 
_ their clear, tinkling melody were entirely deserted; they had com- 
pletely left the region of their first nesting and at a time which left 
an abundance of time for a second brood to be hatched in their new 
quarters. 
In Grant County, New Mexico, another instance of secondary | 
‘migration was noted. It was my misfortune to be obliged to spend 
the spring and summer of 1886 in the extreme southwestern corner 
of that Territory, in the midst of a very dry and barren range of 
hills, ata camp locally known as Apache. At this point I found 
Say’s flycatcher quite common. after March 12, and after the bulk 
_ of the spring migrants had passed on to the north several nests” 
were found, the last being discovered May 26, but by June 1 the 
species had begun to grow less common again, and after the 16th 
of that month none were seen until the first fall migrant made its 
appearance on August 30. The sudden and complete disappear- 
ance of the species from the entire region was undoubted and could 
not be assigned to any local cause. 
a In sp rie connection might be mentioned the nesting at Camp — 
pache of turtle-doves during the fall migration. After the last of _ 
‘e spring migrants had disappeared no doves were seen about
