A few days after, another incident occurred to our voyageurs, which illustrated the habits of a very interesting bird, the "osprey," or fish-hawk, as it is more familiarly known in America.
The osprey is a bird of the falcon tribe, and one of the largest of the genus--measuring two feet from bill to tail, with an immense spread of wing in proportion, being nearly six feet from tip to tip. It is of a dark brown colour above, that colour peculiar to most of the hawk tribe, while its lower parts are ashy white. Its legs and bill are blue, and its eyes of a yellow orange. It is found in nearly all parts of America, where there are waters containing fish, for on these it exclusively feeds. It is more common on the sea-coast than in the interior, although it also frequents the large lakes, and lives in the central parts of the continent during summer, when these are no longer frozen over. It is not often seen upon muddy rivers, as there it would stand no chance of espying its victims in the water. It is a migratory bird, seeking the South in winter, and especially the shores of the Great Mexican Gulf, where large numbers are often seen fishing together.
In the spring season these birds move to the northward, and make their appearance along the Atlantic coast of the continent, where they diffuse joy into the hearts of the fishermen--because the latter know, on seeing them, that they may soon expect the large shoals of herring, shad, and other fish, for which they have been anxiously looking out. So great favourites are they with the fisherman, that they would not knowingly kill an osprey for a boat-load of fish, but regard these bold fishing birds in the light of "professional brethren." In this case the old adage that "two of a trade never agree" is clearly contradicted.
The farmer often takes up his gun to fire at the osprey--mistaking it for the red-tailed buzzard or some other hawk, several species of which at a distance it resembles--but, on discovering his mistake, brings down his piece without pulling trigger, and lets the osprey fly off unharmed. This singular conduct on the part of the farmer arises from his knowledge of the fact, that the osprey will not only _not_ kill any of his ducks or hens, but that where he makes a settlement he will drive off from the premises all the hawks, buzzards, and kites, that would otherwise prey upon the poultry. With such protection, therefore, the osprey is one of the securest birds in America. He may breed in a tree over the farmer's or fisherman's door without the slightest danger of being disturbed in his incubation.
