■2 I 2 Scott on Birds at the Dry Tortugas. [October 



264. Among a flock of Tree Swallows {Tachycineta bicolor) that visited 

 Garden Key on March 29 I saw an individual of this species which I 

 was unable to obtain. This was after the capture of the two individuals 

 already recorded. 



46. Chelidon erythrogaster. Barn Swallow. — A single bird was ob- 

 served, but not procured, on April 8. This was the only note during my 

 stay, but Dr. Goodman took two on April 20, which he sent to me. 



47. Tachycineta bicolor. Tree Swallow. — Not common at the Tor- 

 tugas during my stay. A small flock made its appearance on March 29 

 and remained near by all that day and part of the next. There were in all 

 about a dozen birds, two of which were taken. This is the entire record 

 for the species, and is given in detail as it bears strongly, by a process of 

 exclusion, on other Swallows observed. 



48. Calichelidon cyaneoviridis. Bahaman Swallow. — For a note on 

 the capture of this species, see Auk, Vol. VII, No. 3, p. 265. Another in- 

 dividual of the same species was seen the same day flying about over the 

 enclosure of the Fort, but was not secured. The bird is so easily recog- 

 nized when on the wing, as not to be readily confounded with any other 

 species. 



49. Vireo altiloquus barbatulus. Black-whiskered Vireo. — Dr. 

 Goodman took a single representative on April 29. I did not meet with 

 the species. 



50. Vireo olivaceus. Red-eyed Vireo. — During my stay on the 

 Tortugas I secured a single bird on March 23 and two others on the 29th 

 of that month. These are all the records. 



51. Vireo flavifrons. Yellow-throated Vireo. — A single one was 

 taken at Garden Key on March 24. 



52. Vireo noveboracensis. White-eyed Vireo. — At Garden Key I 

 secured three Vireos that are undoubtedly to be referred to this species. 

 It would seem natural to expect to find the representatives of the White- 

 eyed Vireo at the Tortugas the same as at Key West. I had just come 

 from that island and had there collected a large series of birds — upwards 

 of fifty — that were all unquestionably Vireo noveboracensis maynardi, so 

 that the material that I have has enabled me to substantiate conclusions 

 already advanced in this journal. (See Auk, Vol. VII, No. 1, pp. 15-16.) 

 I am now inclined to believe further, that the White-eyed Vireos breeding 

 on the west coast of Florida, from at least Tarpon Springs south, are not 

 migratory birds and change their location but little at any season. 

 This being the case it would not be natural to expect to find the subspecies 

 maynardi at the Tortugas, if, as I believe fully, no land birds breed at that 

 point. The White-eyed Vireos that are the resident breeding birds at 

 Tarpon Springs are not as extreme examples in the direction of cras- 

 sirostris, structurally, as those collected at Key West; but they have as a 

 whole so far diverged from true noveboracensis, that they appear to me 

 referable to maynardi rather than to the former, and are in much the 

 same category as the Carolina Wrens of the Tarpon region, which, 

 while not as extreme as miamensis, yet diverge so far from true ludovici- 

 anus in the direction of miamensis as to be referable only to that form.
