Clapper Rail. Blue-winged \\'arl)ler. 



King Rail. Louisiana Water-Thrush. 



Turkey Vulture. Kentucky Warbler. 



Barn Owl. Hooded Warbler. 



Acadian Flxcatcher. Mockingbird. 



Fish Crow. Carolina Wren. 



Cardinal. Tufted Titmouse. 



Rough-winged Swallow. Carolina Chickadee. 



Worm-eating Warbler. Blue-gra\- Gnatcatcher. 



Tlie southern limit of the Alleghanian Fauna on the coast is 

 less clearly defined. It includes, however, Long Island and 

 northern Xew Jersey. Its boundaries may be determined by the 

 presence in the breeding season of the following species, few of 

 which are known to nest at sea-level south of our limits : 



Carolina Rail. Purple Finch. 



Alder Flycatcher. Golden-winged Warbler. 



Least Flycatcher. Nashville Warbler. 



Bobolink. Chestnut-sided Warbler. 



Savanna Sparrow. Black-throated Green Warbler. 



Rose-breasted Grosbeak. Wilson's Thrush. 



Thus it will be seen that while the region south of our dis- 

 trict has the Carolinian species mentioned, and the region to the 

 northward has the Alleghanian species just given, we, in this inter- 

 mediate strip, have both Carolinian and .Mleghanian species. 



It is evident, therefore, that from an ornithological stand- 

 point we are most favorably situated, and a comparison of the 

 number of birds found within our limits with the numbers recorded 

 from other districts shows that the causes mentioned have been 

 eflfective in giving us an unusually rich avifauna. Due allowance 

 must of course be made for the much greater area included in 

 all but one of the regions used in comparison.

During the course of a year the bird-life of our vicinity is 

 subject to great changes. Some birds are always with us, some 

 come for the summer, others pass us in the spring and fall in travel- 

 ing to and from their more northern homes, and others still come
