BIRDS OF ESSEX COUNTY. 7 1 



interesting to trace the increase in the number of recognized species of birds for 

 the State as given in the following table from Dr. J. A. Allen's^ List for 1878. 



In 1886, Dr. Allen ^ gave a list of 340 species, 4 extirpated, 19 of probable 

 occurrence, i doubtful, and 4 introduced. 



The latest list for the State, published in 1901, is that of R. H. Howe, Jr.,

Recognized species 362 



Extirpated species 4 



Extinct species 2 



Introduced species 15 



Species erroneously recorded 1 7 



Apocryphal species 2

Before closing this chapter, a few remarks on my own observations on the
