HABITS. The Fish Hawk of North America, whether we regard it as a race or a distinct species from that of the Old World fauna, is found throughout the continent, from the fur regions around Hudson’s Bay to Central America. According to Mr. Hill, it is seen occasionally in Jamaica, and, as I learn by letter from Dr. Gundlach, is also occasionally met with in the island of Cuba; but it is not known to breed in either place. Dr. Woodhouse, in his report of the expedition to the Zuñi River, speaks of this Hawk as common along the coasts of Texas and California. Dr. Heermann mentions it as common on the borders of all the large rivers of California in summer; and Dr. Gambel also refers to it as abundant along the coast of that State, and on its rocky islands, in which latter localities it breeds. I am not aware that it has ever been found farther south than Texas, on the eastern coast. On the Pacific coast it appears to have a more extended distribution both north and south, but nowhere to be so abundant as on certain parts of the Atlantic coast. [Illustration: _Pandion haliætus_ (European specimen).] Mr. Bischoff obtained this species about Sitka, where he found it breeding, and took its eggs; and Mr. Dall procured several specimens near Nulato in May, 1867, and in 1868. They were not uncommon, frequenting the small streams, and were summer visitors, returning to the same nest each season. Colonel Grayson found it breeding as far south as the islands of the Tres Marias, in latitude 31° 30′ north. The nest was on the top of a giant cactus. Mr. Xantus describes it as breeding on the ground at Cape St. Lucas. In the interior it was met with by Richardson, but its migrations do not appear to reach the extreme northern limits of the continent. That observing naturalist saw nothing of this bird when he was coasting along the shores of the Arctic Sea, nor did Mr. Hearne find it on the barren grounds north of Fort Churchill. Its eggs were collected on the Mackenzie River by Mr. Ross, and on the Yukon by Messrs. Lockhart, Sibbiston, McDougal, and Jones. At Fort Yukon, Mr. Lockhart found it nesting on a high tree (S. I. 15,676). On the Atlantic coast it is found from Labrador to Florida, with the exception of a portion of Massachusetts around Boston, where it does not breed, and where it is very rarely met with. It is most abundant from Long Island to the Chesapeake, and throughout this long extent of coast is very numerous, often breeding in large communities, to the number of several hundred pairs. Away from the coast it is much less frequent, but is occasionally met with on the banks of the larger rivers and lakes, and in such instances usually in solitary pairs. Dr. Hayden found it nesting in the Wind River Mountains on the top of a large cottonwood tree.
