SUPPLEMENT TO BIRDS OF ESSEX COUNTY 95 



Since the original Memoir was published the subspecies, circumcincta, or 

 Belted Piping Plover, has very properly been dropped from the Check-List. On 

 August 6, 1907, of a flock of six Piping Plover on Ipswich Beach two were beauti- 

 fully belted, and on May 3, 1914, out of five all but one were belted. 



135 [280] Ochthodromus wilsonius (Ord). 

 Wilson's Plover. 

 Accidental visitor from the South. 



The record from the County for May 8, 1904, still remains unique. The bird 

 was shot by Mr. Charles W. Loud, and I trust he will pardon me for not having 

 given him the credit in the original Memoir. He was the " gunner " mentioned, 

 and to his generosity I owe both the record and the specimen. 



136 [283a] Arenaria interpres morinella (Linn.). 



Ruddy Turnstone; "Chicken Plover"; "Chicken"; "Calico-bird." 



Common transient visitor. May 10 to June 3 ; July 25 to October 16. 



I have nothing to add to my account in the original Memoir of this interesting 

 bird, except that I find in my notes the expression "bald head" and "the mark- 

 ings on the back of the bird in flight suggest a zebra." These may serve to impress 

 on the mind some of the field-marks of the bird. 



137 [289] Colinus virginianus virginianus (Linn.). 



Bob-white; "Quail." 

 Rare resident. 



Eggs: May to September. 



The Bob-white has never recovered from the winter of 1903-4. As stated 

 in Chapter II, the introduction of southern forms of this bird has not sufficed to 

 reestablish it and has probably done harm by weakening the little remaining native 

 stock by interbreeding. 



Dr. Allen^ has found in his examination of the notebooks of Mr. B. F. Dam- 

 sell that this bird is entered nearly every year among the birds seen about Ames-
