ment are obtainable, —the Mourning Warbler is not at all rare, 
and in the West—in Minnesota, Dakota, and Manitoba — it is 
decidedly abundant. Evidently it has no special liking for the 
Maritime Provinces nor for any portion of Canada east of Lake 
Winnipeg, for Canadian observers in general report it rare or 
uncommon. Yet one of the few nests that have been discovered 
was secured by Mr. Kells, near Listowel, in Ontario. This nest 
was in a cedar swamp and placed on the horizontal branch of 
a small tree quite close to the ground. 
The examples I saw in New Brunswick were in small flocks, 
and were a very busy and very merry company, — busy in searching 
for their food, moving in most sprightly and vivacious manner, 
and making merry with sweet voices. The song consists of a few 
simple notes, though sometimes, when hovering while on the wing, 
it is more elaborate. 
CONNECTICUT WARBLER. | 
GRAY-HEADED WARBLER. 
GEOTHLYPIS AGILIS, 
Cuar. Above, olive; head, neck, and breast ashy, darkest on breast 
and crown; white ring around the eyes; chest and belly yellow, sides 
shaded with olive. Length 5% to 6 inches. 
Vest. Hidden on a tuft of weeds, or sunk in mossy mound, in swampy 
woods ; composed of dried grass. 
Eggs. 4-?3 creamy, spotted, chiefly around the larger end, with black, 
brown, and lilac; 0.75 + 0.55. 
This rare species, discovered by Wilson in Connecticut and 
afterwards in the neighborhood of Philadelphia, appears to 
frequent low thickets, and is exceedingly active in pursuit of 
its prey, scarcely remaining a moment in the same place. 
Wilson afterwards shot two specimens of a bird which in every 
particular agreed with the above, except in having the throat 
dull buff instead of pale ash. These were both females, as he 
supposed, of the present species. 
The history of this bird is still interestingly obscure, so much 
has yet to be learned; but gleaning from records made by obser- 
vers in various parts of the country, I am enabled to add a little to 
Nuttall’s account.
