soon fluttered into the darkness. At two o'clock the storm was 
at its height and the birds seemed to be as plentiful as at any 
time during the night, but were more confused and kept up a 
continual loud chirping, particularly the thrushes and vireos. 
These calls seemed to be of alarm, for on other nights they 
were more subdued. In the morning after the storm the whole 
island, but particularly the clearings and the willow bushes, 
was alive with birds. On the ground about the light I picked 
up twenty dead ones of seven species as follows: six olive- 
backed thrushes, seven hay-breasted warblers, one black-poll 
warbler, one magnolia warbler, one mourning warbler, one 
blackburnian warbler, and three red-eyed vireos. 
Another large migration wave occurred on the night of 
September 6, but the night was clear and no birds struck the 
light, although many were seen flying past it. The wind was 
light and from the southwest. On the night of October 5 
occurred the last and largest migration of birds that I saw 
on the island. October 5 was warm, clear and still, and the 
wind was southwest until about midnight, when it changed 
to the north and by morning was blowing a gale. It also 
became very cold. No birds were seen until after the wind had 
changed, when they commenced to fly and by early daylight 
were coming from the southwest across the bay. Under the 
light I picked up a dead male and female black-throated blue 
warbler, a redstart, one myrtle warbler, and one palm war- 
bler. Thousands of these species with some black-throated green 
warblers. vesper sparrows and flocks of juncos also came. 
The migration continued long after daylight, and the birds 
flew low, many of them lighting on the roof, window ledges 
and steps of the light-house and on the ground in the clear- 
ing, especially under the shelter of the willow and other low 
bushes. The bulk of the migrants were myrtle and palm war- 
blers, although there were many of the other species men- 
tioned. 
Captain McDonald toid me that during the spring migration 
of 1910, he picked up one hundred and seventy-four dead 
birds in one morning under the light. These were mostly
