759b. Hylocichla guttata pallasii (Cah.^. Hermit Thrush ; 

 Swamp Robin; Woodchuck; Swamp Thrush; Ground Swamp 

 Robin. 



Plumage of adults : above on head and back olive brown to olive-tinged 

 mummy brown ; tail and rump pale rufous, contrasted in color to the back; 

 below white, tinged with buff on throat and faintly on the breast ; sides of 

 the throat with wedge-shaped black spots ; breast with more rounded, less 

 distinct blackish spots ; ring around eye pale buff, lores black ; sides olive 

 gray ; middle of belly white. Immature plumage : similar to that of adults, 

 but spotted above everywhere in juvenal plumage with large huffy white 

 spots, bordered by black ; more heavily spotted below. Wing 3.60 ; tail 2.80 ; 

 culmen 0.56. 



Geog. Dist. — Eastern North America, breeding from the Alleghany Moun- 

 tains in Pennsylvania northward in the mountains, and from Massachusetts 

 and northern Michigan northward ; wintering from Illinois and southern 

 New England, possibly from Maine, to the Gulf States. 



County Records. — Androscoggin ; fairly common summer resident, (John- 

 son). Aroostook ; summer resident of the bogs and swamps, not common or 

 perhaps more local northward, common in southern sections, (Knight). 

 Cumberland; common summer resident, (Brown, C. B. P. p. 3); common sum- 

 mer resident, (Mead). Franklin; common summer resident, (Swain), Han- 

 cock; common local summer resident, (Knight). Kennebec; common 

 summer resident, (Gardiner Branch). Knox ; summer, (Rackliff). Oxford; 

 breeds commonly, (Nash). Penobscot; common summer resident in south- 

 ern sections, somewhat more local northward, (Knight). Piscataquis; com- 

 mon summer resident, (Homer). Sagadahoc; common summer resident, 

 (Spinney). Somerset ; not very common summer resident, (Morrell) ; locally 

 common northward, but rare or absent from many densely wooded regions 

 of the north, (Knight). Waldo; common summer resident, (Knight). Wash- 

 ington ; abundant summer resident, (Boardman). York; (Adams). 



In general this species arrives in Maine about the middle of 

 April. I have seen individuals near Bangor as early as April 

 sixth, more often about the middle of the month, and very sel- 

 dom indeed in belated seasons individuals have not arrived 

 until even May sixth, while records for other sections of the 

 State show about the same range of variation. In the fall, 

 migration begins in September, lingerers are very frequent up 

 to October thirtieth, and very exceptionally into November. 

 Mr. Brownson records one at Cape Elizabeth, December 25, 

 1904, which might lead to the inference that this species win- 

 ters there along with the Myrtle Warblers and the Robins.
