Hylocichla aliciae.
1888,
September 10.
Lake Umbagog.
Many migrating.
Trip up Cambridge River to Sluice.
As soon as it became dark a heavy flight of Thrushes and
Warblers started and continued all night. I heard many T. aliciae
among the former. Night still, clear, warm.
Hylocichla aliciae.
1897,
June 2.
Lake Umbagog.
Leonard's Pond.
Migrating in numbers.
Clouds gathered at sunset and the night closed in dark
and foggy with light rain. From 8 to 10 P.M. scarce a minute
passed when I did not hear the calls of one or more Gray-cheeked
Thrushes. They all seemed to be passing overhead low down. No
doubt they were migrating. I heard no other birds of any kind.
