Hi All,

The intensity of nocturnal migration this week was about the same as the
week before with a total of 262 night flight calls. However, thrushes were
even more dominant than before, accounting for 43% of all calls. The flight
call of the Hermit Thrush was the most common call of the week with 72.
Second was the American Robin with 40 calls. Typically very few robins are
heard at night compared with the numbers seen immediately after sunrise in
dawn re-orientation. In northern and eastern Nova Scotia, American Robins in
dawn re-orientation during the autumn are flying with a heading between
northwest and northeast under virtually all conditions. The most common
sparrow this week was Savannah Sparrow with 31 flight calls and the most
common warbler was Blackpoll Warbler with 5 calls. Sparrows accounted for
35% of calls and warblers for 6%. No rare or uncommon birds were seen. A
summary list follows.
