Bald Eagle on April i. It was situated on a shelf of the rock 
which projected from the top of one of the huge caverns on the 
steep hillside west of Smuggler’s Cove, The nest proper was a 
saucer-shaped depression in the sand on top of the ledge. But 
it was lined with downy feathers, and encircled by a considera¬ 
ble mass of large sticks and fagots. The nest contained a sin¬ 
gle egg, nearly hatched, which is soiled chalky white, and meas¬ 
ures, 2.76x2.23. On our second visit several immature or ju¬ 
venile eagles were noted, that is, birds in the dark plumage. 
4. Pandion haliaetus carolinensis —American Osprey. 
The Ospreys were quite abundant about the south end of the 
island, and there w'as hardly a rocky promontory or pinnacle 
which was not used as a nesting site. The nests were all either 
on pillars of rock standing directly in the surf, or on over-hang¬ 
ing ledges close above the water. As usual they were bulky 
affairs of course sticks, lined with sea-weed and grasses. One 
nest I climbed to appeared at first sight to contain nothing, but 
on picking over a hummock of grass in the center, I discovered 
the set of eggs. The grass formed a felted mat or lid which 
was attached to the nest on one side, and when closed over the 
nest, perfectly concealed the eggs and protected them from cold. 
When lifted, the lid laid up on the side of the nest, leaving the 
eggs exposed. This is of course quite unusual; all the other 
nests examined were without any such adjunct. Five sets of 
fresh eggs were taken from March 29 to April 3. Eleven eggs 
average 2.48x1.86. Three eggs constituted a full set. On June 
7, nests contained young from a few days old to nearly full- 
fledged. Four specimens of the American Osprey were taken— 
two adult males and two young. 
5. Ceryle alcyon— Belted Kingfisher. 
Several seen during my first visit from March 28 to April 3. An 
adult female was taken March 30. They were always seen 
along the rockiest part of the shore, where they fished mostly 
in the tide pools. 
(>. Phalcenoptilus nuttallii calif or nicus —-Dusky Poor-will. 
Heard each evening from March 30 to April 2; a female was 
shot March 31. They were on the hillsides back of the Cove. 
None were seen or heard during the second visit, so this bird 
was probably only a migrant.
