344 BIRDS OF THE NEW YORK CITY REGION 



overlooked. By nature shy and retiring, an inhabitant of 

 the densest undergrowth, and usually entirely silent when 

 migrating, the bird is never seen unless specially searched for. 

 Most local observers stop Warbler hunting after the height of 

 the migration and go to the coast for Shore-birds; in other 

 words they are far away at just the time when this species is 

 most likely to occur. Those who have seen the Mourning 

 Warbler most frequently are those who visit favorable terri- 

 tory the last ten days in May, when the returns seem small 

 and insignificant compared with the abundance of the pre- 

 ceding week. Mr. Miller's experience at Plainfield and my 

 own in Central Park is that this species is usually recorded 

 on the day of the wave of Blackpolls and female Warblers, 

 which comes after the peak of the migration has passed. The 

 greater rarity of the bird in fall is to be expected; it is just 

 that much harder to find. 



Long Island. Very rare transient, scarcely a dozen records, 

 May 14, 1912, Brooklyn (Mrs. E. W. Victor) to June, 1862; Sep- 

 tember 11, 18, and 26; previously unrecorded is a specimen taken 

 at Baldwin, August 16, 1908 (J. P. Chapin). 



ORIENT. Recorded September 18 and 26. 

 New York State. A rare transient; reported August 18 to 

 October 1, at Ossining (Fisher).

 22, 1910 (Anne A. Crolius); May 26, 1913 (Griscom); May 

 18, 1914 (Anne A. Crolius); May 21, 1917 (Janvrin); June

BRONX REGION. Very rare spring transient, no fall records; 

 Mr. L. N. Nichols has recorded it May 18, 1913; May 20 

 and 31, 1917 and May 18, 1918. 



New Jersey. Recorded from but few sections in our area, but 

 Mr. Miller tells me that in past years, when he was making a special 

 search for Warblers at Plainfield, he used to record it three or 

 perhaps four years out of five in spring. He has no positive fall
