^IO Scott on Birds at the Dry Tortugas. [October 



27. Falco columbarius. Pigeon Hawk. — I secured one and saw 

 several pass over the fort during the last few days of my stay. Later in 

 April Dr. Goodman procured me a series of six of these birds, among 

 which are two individuals that are moulting and one in a phase between 

 the immature and adult plumage. 



28. Falco sparverius. American Sparrow Hawk. — Some dozen or 

 more individuals were observed during my stay, and several were taken. 

 They are said to be resident at Garden Key, i.e., there are always some 

 representatives present, but I could find no signs of their having nested 

 on the island or on the others of the group, and so believe that while 

 they may be always represented in the bird fauna of the island, yet it is 

 by different individuals passing some little time at this point. 



29. Pandion haliaetus carolinensis. American Osprey. — A single 

 one was noted. 



30. Coccyzus americanus. Yellow-billed Cuckoo. — This species 

 was not common, but I obtained one on the 7th and another on the 9th 

 of April. Dr. Goodman collected four individuals, April 28-30. 



31. Ceryle alcyon. Belted Kingfisher. — There were one or two 

 representatives of this species present on Garden Key during my stay, 

 but the birds were never noticed as being at all common. But their 

 numbers were greatly augmented during the later part of April, for Dr. 

 Goodman sent me a large series which he secured at that time. 



32. Sphyrapicus varius. Yellow-bellied Sapsucker. — This was 

 the only Woodpecker observed at the Tortugas, where it was not 

 uncommon during my stay. In all I secured six representatives, the first 

 on March 25 and the last on April 8; five of these are females. The only 

 male noticed was taken on March 25 and approaches the subspecies 

 nuchalis, having a few red feathers faintly representing the nuchal 

 band. The bird is also of a decidedly deeper and brighter yellow below 

 than average specimens of typical varius. 



33. Antrostomus carolinensis. Chuck-will's-widow. — A single 

 bird (a male) was secured on April S, and Dr. Goodman sent me three, 

 two of which were taken April 19, and one Ma}' 1. 



34. Chordeiles virginianus chapmani. Florida Nighthawk. — I 

 obtained a Nighthawk on April 5, and Dr. Goodman took two others on 

 April 13 and 14 respectively, all of which I refer to this subspecies. 



35. Trochilus colubris. Ruby-throated Hummingbird. — On the 

 24th of March I noticed several male birds, which were the first I had 

 seen at this point. Two of these were seen half a mile from the shore, as 

 they passed by the open boat in which I went from one key to the other. 

 From this time they were more or less common till the 29th, when the 

 migration seemed to be at its height and I took seven adult males. 

 After about Apiil 2 I did not see any. Only one female was noted 

 during my stay. The adult males were, however, as abundant, if not 

 more so, than I ever, noted them at any point on the mainland in the 

 spring migration. It was very curious to meet these birds, when at 

 considerable distance from land. Frequently while fishing and collecting
