342 BIRDS OF THE NEW YORK CITY REGION 



CENTRAL PARK. Very rare transient; June 13, 1892 (F. M. 

 Chapman); May 24, 1908 (Hix); May 20 and 28, 1909 (Anne 

 A. Crolius); May 18, 1910 (Anne A. Crolius); May 16, 1921 

 (Charles Johnston). 



BRONX REGION. Bred formerly at Riverdale (Bicknell), 

 long since extirpated; now very rare, recorded May 20, 1917 

 (L. N. Nichols). 



New Jersey. The only breeding locality in our area was the 

 Palisades near Englewood, where it is now extinct; at present an un- 

 common transient near Elizabeth, where Mr. Urner reports it 

 eleven times in the last six years, May 14, 1916 to May 23, 1920, 

 and August 20, 1916 to September 21, 1919; now a rare spring tran- 

 sient near Englewood; never recorded in twenty-five years near 

 Plainfield (Miller); casual near Montclair, May 8, 1911 (Rowland). 

 It seems evident, therefore, that the Kentucky Warbler is extinct as 

 a summer resident, and as a transient occurs only near the Hudson 

 River valley, and casually elsewhere. 



ENGLEWOOD REGION. Formerly a fairly common summer 

 resident on the west slope of the Palisades just south of Engle- 

 wood, the last pair nesting in 1914; only once recorded since; 

 May 6, 1919 (Granger) to early July (Hix). 



CONNECTICUT WARBLER (Oporornis agilis) 

 This shy Warbler is exceedingly rare in spring, but is 

 irregularly present in the fall, apparently absent some years, 

 really common occasionally. It occurs in the densest growths 

 of swampy woods, or the borders of weedy pastures. In 

 such a locality a large Warbler will flush suddenly and dis- 

 appear after a short flight, nor will it be easily found again. 

 It is very thrush-like in perching motionless for some time 

 after being flushed, and the student can take advantage of this 

 habit to get an observation. Perhaps the swampy woods of 

 Van Cortlandt Park is the best locality near the City to 

 find this bird, where it should be looked for anywhere between 

 the last days of August and the first days of October. In any 

 plumage the Connecticut Warbler differs from the Mourning 

 in having an eye-ring. The under tail-coverts are twice as 

 long as in the Mourning Warbler, and extend for two-thirds the 

 length of the tail. Females and immature have a brownish
