AMERICAN OSPREY. 
ANDION HALLETUS, as the Fish Hawk or Osprey 
is called in ornithological language, is found from the fur 
region surrounding Hudson’s Bay to Central America, and 
from Labrador to Florida, excepting Boston Harbor, on the 
Atlantic Coast, and almost from Alaska to the southern 
extremity of the peninsula of Lower California on the 
Pacific seaboard. Birds have been known to nest on the 
rocky islands of California, and about Sitka, according to 
Bischoff, as well as along the small streams in the vicinity of 
Nulato. From Long Island to Chesapeake they breed in 
vast communities, which often number several hundred pairs, 
but away from the sea-coast they are only occasionally met 
with on the margins of rivers and lakes. Dr. Hayden found 
several pairs nesting on the summit of high cottonwood trees 
in the Wind River Mountains, and Mr. Allen observed the 
birds particularly abundant about the lakes of the Upper St. 
John’s River in Florida, six nests being noticeable within a 
single circle of vision. Salvin claims that they nest on both 
coasts of Central America, but more especially about Balize, 
although on the islands of Trinidad, St. Croix, Jamaica and 
Cuba they are seen at all times except during the breeding- 
season. 
Below Philadelphia, and in the south-eastern counties of 
Pennsylvania bordering on the Delaware, individuals have 
been occasionally observed. Their arrival is about the 
beginning of March, often when the streams which they 
frequent are fettered with icy bonds, and their departure 
occurs about the twenty-fifth of September, and frequently,
