they did. But I claim that the Osprey was their neighbour. 
Dr. Heysham distinguishes between the food of the ‘‘ Sea Eagle” 
and that of the White-tailed Eagle. Of the former, he says 
that “its food is principally fish.” Of the latter, he says that 
though it sometimes feeds on fish, yet “it feeds chiefly on land 
animals,” thinking no doubt of young lambs and carrion, which 
in Scotland constitute the chief food of this Eagle. I hope that 
the passages cited may clear up the confusion that has 
existed between the Osprey and the White-tailed Eagle, among 
our lake hills. 
Before I take leave of the subject, allow me to cite one more 
witness to the former presence of the Osprey in the north of 
England. 
The late Mrs. Howard, of Corby Castle on Eden, about 1831, 
published privately two volumes of personal Reminiscences. 
Writing of the banks of Eden (vol.i., p. 97), she says,— 
“We will descend the Sandwalk to the right of the Tempietto, 
where observe, among others, the Osprey Eagle tree,—an old oak 
so called from having been the resort of these voracious birds, 
which feast on Salmon.” This suggests that a third eyrie may 
possibly have existed long ago in the north of Cumberland. 
During the last half century a good many Ospreys have doubtless 
visited our faunal area; but though my records date from 1837, 
and refer to all parts of our district from the Solway to Furness, 
the list of Ospreys that have been shot locally is a small one as 
compared with other parts of England.

particularly abundant here; one day in May I counted sixty-eight emerge 
from a small opening at the upper gable of my house. On May 17th I 
counted fifty-seven from the same place, and during last week they came 
out at 8 o’clock in the evening exactly. On the 19th I waited for them 
from half-past 7, and they came out as usual at 8; I shot three of them 
as they flew away, and they were all females. This evening, being cloudy 
and raining, they came out exactly at the same time. They emerge from 
their dormitory in rapid succession, and in about five minutes:they are all
