Migration of Hawks. — Mr. Robt. Barbour’s letter in the January num- 
ber of ‘The Auk’ (XXV, pp. 82-84) describing the migration of a large 
number of hawks has interested me very much. For a number of years 
past I have observed the migration of hawks, and have repeatedly seen, 
I should say, thousands of hawks. On September 22, 1907, the numbers 
exceeded, I believe, any ever observed before. I was on the top of a 
mountain near Stag Lake, Sussex County, N. J., about 1200 feet above 
sea level, from where I had an unobstructed view for miles of country all 
around me. My object was to observe the migration of hawks, and I 
was armed with a Hensoldt Binocular eight power glass. The day was 
clear, and at one time late in the forenoon, several thousand hawks, Broad- 
wings mostly, were in view. They came from a northeasterly direction 
which would take them directly to the Shawangunk Mountain, Ellenville, 
and Lake Minnewaska, N. Y., sixty miles northeast from my place, where 
a similar flight was observed by Mr. Barbour and Mr. Kirk Monroe. A 
constant stream of birds, very high up, could be seen for a long while, and 
they were going in the direction of the Delaware Water Gap. Over the 
valley to the southwest of me, the birds seemed to collect into an immense 
flock, while hundreds, if not thousands of birds were gyrating around and 
around, describing smaller and larger circles in the air, in heights of from, 
I should judge, 600 to 2,000 feet above the earth. Most birds were Broad- 
wings. There were, however, other hawks such as Red-tails and Red- 
shoulders among them, while the “ Aceipiter” genus was represented by 
some Cooper’s Hawks and more Sharp-shinned, which, however, were 
mostly flying lower and took no part in the general evolution. Some days 
I have observed about every species of hawks that we find in this part of 
the country, from the same stand. By decoying them with either a live 
or mechanically moving stuffed Great Horned Owl, I have taken some 
very successful and interesting photographs, and have secured hundreds of 
specimens with the gun. 
Where this annual migration of hawks begins and where it ends, I do 
not know. If notes could be collected further north and south than 
Ulster County, N. Y., and Sussex County, N. J., the lane of migration 
might be well defined. The most extensive migrations occur just before 
a storm. — Justus von Lengerke, New York City.
