44. Pandion carolinensis — Fish Hawk. 

 — • P. haliaetus (Lin.) — Osprey; 

 but separated by some antliors. 



3 eggs sent are from different nests. " Taken on Hogg Island, 

 Virginia, 31/5/71, by myself I think I saw more than 30 nests 

 on the islands. They were built in pine trees, some pretty high, 

 others quite low. Some of the trees were dead, and so rotten 

 that it was not safe to climb them; others alive, and showing no 

 signs of decay. This hawk does not build a very large nest the 

 first year, but adds to it each season, and I saw some that were 

 fully 3 feet deep. It was late when I visited their breeding 

 station, and most of the eggs were nearly ready to hatch." In a 

 former letter, Mr Jones tells me that, on the same tree with the 

 nest of the Fish Hawk, he found 3 or 4 nests of the Great Blue 

 Heron (Ardea herodias). 



These eggs measure — 2*5 in. by 1*8 in., 2*4 in. by 103 in., and 

 2*04 in. by 1*8 in. They are in every respect similar to the eggs 

 of the European bird. 



Mr Jones has since sent me several sets of these eggs. {V. Egg 

 Bk. Mus. F. and H.-B, p. 187). 



The Geog. Eange — " Thoughout temperate N. America " (Baird). 



48. Buho virginianus — Great-horned Owl. 



The representative in N. America of our Bubo ignavus, or Eagle 

 Owl. 



" Nest of two eggs sent. Taken in Portland, Conn., by a boy 

 in the employment of W. W. Coe. Mr Coe obtained a nest of 2 

 eggs from the same bird in March; consequently, this was a second 

 laying. One of these eggs is more elongated than the other, and 

 the same was the case with the other set. I consider this a fine 

 set of eggs, and they are amongst our most valuable eggs, being 

 rarely obtained in this i^art of the country. Tliey usually occupy 

 an old hawk's nest; and the one from which these eggs were taken, 

 was built and occupied by a Red-tailed Hawk in 1870." 



The Geog. Range — "The whole of N. America: runs into 

 varieties " (Baird). 



49. Scops asio — Mottled Owl. 

 2 eggs sent. Mr Jones write 

 enough to find the nest of this species, though they breed in this 



2 eggs sent. Mr Jones writes : — " I have never been fortunate
