l6 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB 



this bird. We might infer from this that the group or beginning-race of this 

 warbler that formerly wintered in the North was either largely killed out in the 

 previous winter or learned the advantages of a more southern station. I expect it 

 to return to its usual numbers. 



The Golden-crowned, Kinglet, a bird that is accustomed to winter in cold 

 regions, also appeared to have suffered very much from the severe winter of 

 1917-18, for it, too, came in very small numbers in the winter of 1918-19. This 

 was clearly shown, not by general impressions which are apt to be misleading, but 

 by actual counts made in the Bird-Lore Christmas Census of 1918. Mr. Francis 

 H. Allen^ found that while 500 of this species were recorded in 1917, in 1918 only 

 76 were recorded throughout its entire range east of the Rocky Mountains. 



In the original Memoir I had collected only six records for the Mockingbird 

 for Essex County. Four of the birds were shot. In the last dozen years the bird 

 has become almost a resident, for individuals have been observed in various 

 places in the County at all times of the year. 



In this Supplement, one species, — ^the Passenger Pigeon, — ^has been removed 

 from the regular list and put among the extinct species. The Belted Piping 

 Plover is now no longer considered a distinct subspecies and is removed. 



Four species, — the Ivory Gull, Brown Pelican, White-fronted Goose, and 

 Clapper Rail, — have been removed from the doubtful list and added to the 

 regular list. 



Eleven other native and introduced species have been added to the regular 

 list, namely: Kumlien's Gull, Western Willet, White Gyrfalcon, Yellow-headed 

 Blackbird, Rough-winged Swallow, Prothonotary Warbler, Blue-winged Warbler, 

 Louisiana Water-Thrush, Hooded Warbler, Labrador Chickadee, Greenland 

 Wheatear, and Starling. This makes a total of 335 species and subspecies for 

 the County.
