CLXXIII. CENTORUS Swainson. 1837. 
409. Red-bellied Woodpecker. 
Centurus carolinus (LINN.) BONAP. 1838. 
A few pairs breed near London. I have found several nests, 
usually in the dead top of a living maple or beech tree, and from 
forty to seventy feet above the ground. They nest early in the 
year, and I find them excavating usually about April 20 to goth. 
Hardly a year passes that I do not locate one or more breeding pairs: 
Until about 1885 they were very abundant in the counties west of 
London, Ont., but their numbers have greatly lessened of late. (W. 
E. Saunders.) Rare about Toronto; commoner in southwestern On- 
tario. (J. H. Fleming.) A female was taken in Toronto, Ont., 
May 19th, 1885. (E. T. Seton.) On July 27th, 1894, I took 
an immature specimen of this species at Twin Lakes, border of Lake 
township, northeast of Havelock. (jJ. Hughes-Samuel.) Accidental 
visitant in the Montreal district; rare. Mr. Kuetzing says this 
species occurs in the Eastern Townships, but I have not observed 
it near Montreal and will treat it as a straggler until more is known 
of it in this district. (Wunlle.) 
CLXXIV. COLAPTES Swainson. 1827. 
412a. Northern Flicker. 
Colaptes auratus luteus BANGS. 1898. 
Herr Méschler has recorded the receipt of a specimen from Green- 
land in 1852. (Arct. Man.) An accidental straggler was procured 
from the mainland near Akapatok island, Hudson strait, in October, 
1882. Reported to be a common summer visitor to Northwest 
river, Labrador. (Packard.) Observed all along the Moose river 
to Moose Factory, and a few as far north as Fort George in Labrador, 
June, 1896, and to Cockpenny point in 1904. (Spreadborough.) A 
summer visitor and tolerably common in Newfoundland. (Reeks.) 
One seen on the Humber river, Newfoundland, October, 1898. 
(L. H. Porter.) Fort Churchill, Hudson bay. (Clarke.) Not com- 
mon at Lake Mistassini, northern Quebec, in 1885. (J. M. Macoun.) 
We found flickers rather common throughout the region between 
Lake Winnipeg and Hudson bay and saw several at Fort Churchill,
