46 AVIFAUNA COLUMBIANA. 



streets, it is true, but they were comparatively plentiful about the city, 

 no fewer than nine specimens having been taken to our knowledge during 

 the second and third weeks in May. Some of these were in the finest 

 feather we ever saw. We can give no directions for finding Cape Mays, 

 except that they are birds of the high, open woodland, like most of the 

 genus Dendrceca. Besides being so rare, they are shy, and not likely to 

 be secured except through careful searching [12G] 



4-5. (^0.) Dendrceca discolor (Ulls.) Bd. Prairie Warbler. 



This is chieily a spring and autumn migrant, being most numerous 

 during those periods, but some breed here. It is one of the earlier 

 arrivals, about the 20th of April ; its disappearance we have failed to 

 note. It frequents almost exclusively patches of cedar and pine trees, 

 in sterile, sandy fields, particularly old fields growing up to scrub pines? 

 where it can almost certainly be predicted. Many such are found on 

 the hillsides bordering Rock Creek, and there the peculiar-mannered 

 little bird with the singular chirring notes will always be found in due 

 season. [1137] 



46. (79.) Dendrceca dominica (Linn.) Bd. (D. superciliosa of the original edition.) 



Yellow-throated Warbler. 



This is a southern species, of rare and casual occurrence with us. 

 We have learned of but two instances — a specimen having been obtained 

 in 1842, which is still preserved in the Smithsonian, and another shot at 

 Arlington September 7, 1881, by Mr. William Palmer. This is now No. 

 81858 of the United States National Museum, as noted by Mr. Eidgway 

 in the Bulletin of the Nuttall Ornithological Club, vii, 1882, p. 253. Mr. 

 Palmer also informs us that he found the bird "abundant" at Cherry- 

 stone, on the eastern shore of Virginia, in July, 1881. [129J 



47. (8t.) Dendrceca palmarum (Gm.) Bd. Yellow Red-poll Warbler. 



A spring and autumn migrant, rather rare ; does not breed with us. 

 It arrives in spring, about the 1st of May, and returns tardily in the fall- 

 not until late in September, departing again not before the middle of 

 Oetober, when all the other Warblers excepting the Yellow-rumps have 

 taken leave of us. Its habits are peculiar, in comparison with its con- 

 geners ; for it is something of a ground Warbler, like species of Oporomis, 

 and in its manners reminds one somewhat of a Titlark. It frequents 

 old corn and buckwheat fields, hedge-rows, and road-sides, often asso- 

 ciating with Yellow-rumps, Titmice and various sparrows. [132, 133 J 



Specimens from this locality are supposed to be referable to Mr. 

 Ptidgway's var. hypochrysea ; but one in the National Museum, shot May 

 18, 1881, by Mr. Lewis McCormick, is said to be typical palmarum. 



48. (~3.) Dendrceca pinus (Bartr.) Bd. Pine-creeping Warbler. 



A summer resident ; in this respect only matched in the genus by 

 CBstiva and discolor. Arrives early in March and remains until October. 

 It is not very common and breeds but sparingly. It is to be found in 

 high, open woods, particularly pines. [134]
