328 BIRDS OF THE NEW YORK CITY REGION 



appearance and coloration, but is bright bluish olive green 

 above instead of dull grayish olive green. It ranges so high, 

 however, that the student will get many a neckache in his 

 efforts to identify it. In 1920 a single bird summered in the 

 Catskills, and in 1922 Mr. George W. Gray and others 

 made the astonishing discovery that this species was nesting 

 in Dutchess County, New York, and it was observed in 

 several localities during May as a transient. Should this 

 state of affairs continue and the bird really extend its range 

 eastward, it is possible that the Cerulean Warbler would be 

 observed more frequently on migration in this vicinity, and 

 students are urged to keep the sharpest possible lookout for it. 

 Long Island. One specimen taken many years ago in Brooklyn. 

 New York State. 



CENTRAL PARK. One recorded as seen by Basil H. Dutcher 

 May 5, 1885. 



BRONX REGION. An adult male in full song most satis- 

 factorily studied May 14, 1921 by Dr. Wm. H. Wiegmann. 

 He made a rough sketch of the bird and wrote a brief descrip- 

 tion of his observation in the field. Both were immediately 

 recognizable, and he of course knew at the time exactly what 

 he was seeing. 



New Jersey. Specimen taken at Boonton, September 1/1887 

 (Sylvester Judd). 



ENGLEWOOD REGION. One collected at Palisade Park, 

 September 25, 1909 (J. A. Weber). 



CHESTNUT-SIDED WARBLER (Dendroica pensylvanica) 

 Another common transient Warbler throughout our area, 

 and a common summer resident north of the coastal plain in 

 scrub growth. It arrives the first week in May, starts moving 

 south about the middle of August and is casual in October. 

 Comparatively few are seen in fall. The fall plumage is quite 

 different from the spring plumage, but is nevertheless distinc- 

 tive. No other Warbler is bright yellowish green above, 

 pure white, unstreaked below, with an eye-ring and wing-bars.
