walking through one of their favourite retreats one can be almost 
sure to hear the warning or scolding notes of any birds that may 
chance to be disturbed. Any that I have heard singing have been 
invariably perched on a dead branch well up from the ground. On 
seeing that they are observed they will dart to thick cover, in which 
case one is not likely to see them again for some time. On 30th 
July, 1895, I met with a party of adults and young in a thick patch 
of cedars a few miles west of Toronto. From 11th to 30th May, 
1899, I saw from one to six almost daily. (J.. Hughes-Samuel.) 
Fairly common during migrations, and breed in fair numbers. 
Arrives about May 16th and leaves about September ist. (A. B. 
Klugh.) 
I was agreeably surprised to find this species breeding abund- 
antly at Pembina. At the end of June I found a nest supposed to 
be of this species but the identification was not at all satisfactory. 
(Coues.) A common summer resident of scrub lands, throughout 
Manitoba. (E. T. Seton.) A tolerably common summer resident 
at Aweme Manitoba; arrived May 24th, 1903, and disappeared 
early in September. (Criddle.) This species was seen at Old Wives 
creek, eastern Saskatchewan, in May, 1895. (Spreadborough.) A 
common breeding species throughout Manitoba in the wooded dis- 
tricts; noted west of that province in 1906 at Touchwood hills and 
Saskatoon, Sask., and Battle river, Alta. (Atkinson.) A possible 
hybrid of this species and O. tolmiet was taken at Grand rapids of 
the Saskatchewan. (Nutting.) This was a common species round 
Lake Manitoba in June, 1881. A nest was taken at the ‘‘narrows”’ 
on June 16th. (Macoun.) 
BREEDING NotTes.—On June 14th, 1902, a nest with four eggs 
was found in a damp place near Montreal. It was built in a clump 
of golden rod three inches above the ground and composed of grass 
stems and leaves lined with thin black rootlets and hair. Nest 
4x 3 and 2.25 x 1.75. Another nest was found in the forks of a 
small bush, the brim six inches from the ground and made of dried 
leaves, grass and bark, with a lining of hair-like roots, nest 4.25 x 3 
and 2.25 x 1.75. ‘(Garneau.) Nest found near Tetreauville, Hull, 
Que., in a low bush, rather large for the size of the bird, composed 
of moss, leaves and other vegetable matter, lined with grass and
