TURKEY VULTURE. 
Amongst our earliest migrants, reaching the lower sections 
of the State immediately after the lifting of the ice-embargo, 
the Vultures are never seen in sufficient numbers to record 
them more than fairly common in some partially restricted 
portions of the country. After a few years of observation, I 
learned to Jook for their appearance about the 25th of March, 
but have frequently been compelled to wait until the first day 
of April. The first seen are more commonly a single pair, 
attention having been drawn to them by their flying in large 
circles while gradually making progress northwardly along 
the general course of some considerable stream. A few days 
later, a larger number is occasionally noticed, perhaps a flock of 
half a dozen; rarely more, working their way to higher lati- 
tudes. Formerly an average share of them remained along 
the St. Croix, St. Peter, and Mississippi rivers to breed, but 
with the general progress of improvements, and the employ- 
ment of steam whistles on the steam boats and the mills, and 
on the railways, they have, in common with many other form- 
erly rather common species of the larger birds, become locally 
much rarer. The earlier nests are built, if so meagre an 
attempt may be galled building, about the middle of April, 
(in 1864, April 10th), but later ones are occasionally found. 
Mr. Lewis reports them as late as the 5th of May on Lake 
Traverse, and the 15th of the last month in Becker county, 
which is considerably further north. As intimated, the nests 
are the merest apologies when attempted at all,; but in the 
few instances of my own observation, they were only the 
naked ledge overhanging the water, on which were a few
