invariably see in spring a few pairs in the “scrub,” especially 
where swampy. In their summer-homes they. inhabit copses 
and thickets in open spots, finding their food in piles of brush, 
on the ground, etc., never, however, jerking their tails in the 
manner of their relations. 
(da). The Mourning Warblers have a sharp chirp, a feeble 
tsip, and a warbled, liquid song (likened to that of the House 
Wren, Water Thrush, and Maryland Yellow-throat), which is 
generally delivered from a high perch. 
III. OPORORNIS 
(A) aeriis.25 Connecticut Warbler. 
(A migrant in New England.. Extremely rare in spring, 
and generally rare in autumn, though more than a hundred 
specimens were taken at Cambridge in two years, when these 
birds were extraordinarily abundant in fall.) 
(a). About 54 inches long. Above, olive-green, becoming 
ashy-tinted on the head. Eye-ring whitish. Throat (and up- 
per breast), ashy or brownish. Other under parts, yellow. 
Crown, olive in autumn. 
(0). I believe that the nest and eggs of these birds have 
never been discovered by any ornithologist. 
(c). The Connecticut Warblers have hitherto, with two re- 
markable exceptions, been very rare migrants through Mas- 
sachusetts ; but they may become more common hereafter. I 
‘have seen them but once in spring (then only an individual on 
the tenth of May), and but a few times in September. The 
‘following observations were:made at the Fresh Pond Marshes 
‘of Cambridge, in the autumus of 1870 and 1871, and illustrate 
the habits of these birds. 
“Mr. Henshaw found them almost constantly engaged in 
‘seeking their food on the ground. When startled they would 
fly up to the nearest bush, upon which they would sit perfectly

know no instance of its so doing. It has been known to breed in Eastern New 
York.
