CATALOGUE OF CANADIAN BIRDS. 665 
with the water. It contained one egg and three very young birds; 
there seemed no scarcity of excited birds as I floundered through 
the bog. 
679. Mourning Warbler. 
Oporornis philadelphia (WiLs.) WOOLSEY. 1880. 
One specimen obtained at the Fiskinzes in 1846, another at 
Julianshaab in 1853. (Arct. Man.) Rare about Halifax, but 
common in the interior of Nova Scotia as a summer resident. 
(Downs.) Rare summer resident in Kings co., N.S. (H. F. Tufts.) 
Apparently rare on Prince Edward island, though a few were found 
at Souris in the bushy edges of dry fields, adjoining woods. (Dwzght.) 
A rare summer resident at St. John, N.B. (Chamberlain.) Not 
uncommon in the upper part of the Restigouche valley, N.B. (Brit- 
tain & Cox.) 
A rare species around Quebec; taken at Beauport. (Dionne.) 
Transient and scarce visitant around Montreal. Has been shot 
at Outremont and Hochelaga. (Wzntle.) A moderately common 
summer resident around Ottawa. (Ottawa Naturalist, Vol. V.) 
A few of these birds breed in the county of Leeds, Ont. I met 
with the nest on 31st May, 1893, containing four eggs much resem- 
bling those of the yellow-throat. A peculiarity of the nest, and 
one I believe generally observed, is that it is lined with black fibres 
and rootlets and not as the yellow-throat with fine grass and hair. 
This bird is a common species during migrations on the Magdalen 
islands and probably breeds there also. (Rev. C. J. Young.) A 
fairly common resident in Parry Sound and Muskoka districts. It 
is one of the latest arrivals in spring. Regular migrant at Toronto, 
not uncommon; rare summer resident, breeds. (J. H. Fleming.) 
Quite common along the Parry Sound railway in Algonquin park, 
Ont., always in dry thickets. Common in low bushes along the 
C. P. Ry. at Missinabi, Ont.; one seen about 100 miles down the 
Missinabi river. (Spreadborough.) A not uncommon summer 
resident all over western Ontario. (W. FE. Saunders.) Uncommon; 
but perhaps considered more so than it really is as the bird is such 
an adept at keeping out of sight. Still if one knows their haunts 
and reaches them about 18th to 24th May he may see a few if he 
will only sit down close to the ground and keep quiet; though on
