the first week of November, remaining the latest of all the 

 Warblers. Is sometimes seen in spring before the snow 

 is gone. 



77. Dendroica discolor Baird. Prairie Warbler. Usually 

 very rare, but was rather common in May, 1862. Have 

 not known it detected here in summer, though it breeds 

 in other parts of the State. The region is not of the kind 

 they appear partial to, rather preferring rocky barrens, 

 with scattered, dwarfish cedars arid pines. Its habits are 

 peculiar, and its notes are very much so. 



Of the twenty-two species of Dendroica inhabiting the 

 United States, thirteen have been found at Springfield, and 

 one other (D. ccerulea) may occur as accidental or ex- 

 tremely rare. Four of them (D. virens, pinus, pennsylva- 

 nica, wstiva) are known to breed here, and two others 

 (D. Blackburniw, castanea) have been taken in the breeding 

 season. None are permanent residents, and none are seen 

 in the winter. The remaining five (D. coronata, striata, 

 maculosa, tigrina, palmarum) are at present known merely 

 as spring and autumn visitants. D. coronata is most abun- 

 dant ; striata next so ; virens, canadensis, maculosa, cesti- 

 va and palmarum are but little less common ; Blacliburnice 

 is more rare ; castanea and discolor are quite rare, while 

 tigrina is extremely rare. The earliest to arrive brepinus 

 siud palmarum, commonly appearing early in April ; striata 

 is rarely seen before May 30th ; the others commonly ar- 

 rive from May 5th to 1 2th, and stragglers remain till June. 

 D. coronata is decidedly gregarious in its migrations, and 

 is everywhere about equally abundant. The others are 

 usually seen in small parties, and keep pretty closely to 

 the woods, except D. wstiva and palmarum, wstiva being 

 never found in the deep woods. 



78. Wilsonia* pusilla Bonap. Black-capped Flycatch- 

 ing Warbler. Rare. Have taken it May 12th to the 18th, 

 and August 23d. Probably breeds. Generally found in 

 swampy thickets. 



Probably the Hooded Flycatching Warbler (Wilsonia 

 mitrata Bonap.) will yet be found here. 



* The prior use of Wilsonia in Botany does not appear to me to be suffi- 

 cient reason for discarding its use in Ornithology.
