OF NEW ENGLAND. 15} 
usually at that season they inhabit the most southern United 
States and even warmer climates. I have several times, in 
December and January, found them near Boston, in swamps, 
where they were feeding upon the berries, and also among 
cedars.38 
Whilst here in spring, they are to be found on the road- 
sides, in swamps, in pastures, in ‘‘scrub-land,” and amongst the 
trees and shrubbery of cultivated estates, but rarely in woods, 
though in northern New England such are their summer-haunts. 
They generally move about in flocks, often very loose ones, 
inclusive of immature specimens in various stages of colora- 
tion. They prefer the orchard and hard-wood ‘trees to the 
pines, and usually take their perch among the latter to look 
out for passing insects. They more generally frequent the 
higher than the lower branches, and from these fly to snap up 
insects in the air, usually at some distance, afterwards often 
alighting in another tree. At other times, unlike the fiycatch- 
ers, they glean among the branches and look for insects among 
the foliage and blossoms. In autumn their habits are essen- 
tially the same, except that they are more upon the ground, 
feed more upon berries, sometimes those of house-vines, and 
show a greater liking for hedge-rows and like places, where 
they often associate with the ‘‘ Yellow Red-polls” or with the 
sparrows. They may generally be distinguished at a distance 
by their habit of being much in the air, and of taking long 
flights (as compared with those of other warblers) at quite a 
height above the ground. 
(d). The ‘* Yellow-rumps” have a soft chip, and a loud check 
or chuck (which sometimes is softened to chup). I have often 
heard them sing in May, throughout the day, much like the 
Purple Finch, but without the richness, fulness, continuity, or 
melodiousness of that bird’s music, especially if heard from a 
near standpoint. This song is often varied, and sometimes 
has reminded me of certain of the ‘‘ Maryland Yellow-throats’ ” 
38 Mr, Charles C. Abbott states that they pass the winter in New Jersey.
