Not more than five of these, however, advance regularly to 

 the northern limits of the Fauna. The southern limits of the 

 Alleghanian Fauna on the coast is less clearly defined. It includes, 

 however, Long Island and northern New Jersey. Its boundaries 

 are in a measure defined by the presence in the breeding season 

 of the following species, none of which are known to nest south of 

 this vicinity at sea-level. 



Carolina Rail. Nashville Warbler. 



Purple Finch. Chestnut-sided Warbler. 



Golden-winged Warbler. Black-throated Green Warbler. 



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

 has the Carolinian species mentioned; and the region to the north- 

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

 mediate or neutral strip, have both Carolinian and Alleghanian 

 species. 



It is evident therefore that from an ornithological standpoint 

 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 effec- 

 tive 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 

 traveling to and from their more northern homes, and others still
