1903, became common by May 14th, 1903, last seen October toth. 
(Norman Criddle.) This bird arrives on the banks of the Sas- 
katchewan at Prince Albert in May and breedsinthickets. (Cow- 
beaux.) Abundant at Grand Rapids and Chemawawin; breeding 
in the latter place. ((Vutting.) I have the nest and four eggs 
with the parent bird that were collected at Red River, Alberta, 
June 14th, 1898, by Mr. W. Wenman. (W.Rame.) This is a 
common migrant at Indian Head, Assa., it was first seen on April 
25th, and the last ones disappeared on June 2nd, 1892; first seen 
on April 30th, 1894, at Medicine Hat, Assa. Those shot were all 
males. By May rith they were very abundant in willow thickets,

of the Lob-stick River, Alta., June 17th, 1898, where they were 
breeding; seen in large ‘flocks at the Henry House, September 
2nd; a spring migrant at Banff, Rocky Mountains in 1891; arrived

Renfrew Co.; it was built near the top of a cedaragainst the stém, 
about eight or nine feet from the ground and close to the water, 
and on that date contained four fresh eggs; I easily identified the 
bird by its white throat and other characteristic markings; though 
I often saw the bird in the interval I did not again meet with its 
nest until June 11th, 1902, when I found anest in asecond growth
