maple. (/. H. Fleming.) Common amongst balsam fir in Algon- 
quin Park, Ont., June, 1900. (Spreadborough.) Reaching us in 
the first week in May at Toronto this bird becomes very abun- 
dant. The female of this species occasions probably as much 
trouble with the novice as regards identification as any of our 
birds, flycatchers excepted; btit the white spot at the base of the 
primaries is indisputable ev idence and when not clearly apparent 
always shows when the feathers are parted. Found young 
just from the nest at Havelock, Ont., July, 1894. (/. Hughes- 
Samuel.) Rare summer resident in Middlesex Co; “Ont. but 
more common in North Bruce. Fairly common at London, Ont., 
as a migrant. (W. &. Saunders.) Mostly a passing migrant at 
Guelph, Ont. A few pairs breed. Arrives about May 12th, leaves 
about Sept. 26th. (A. B. Klugh.) Summer resident at Penetan- 
guishene, Ont. (A. /. Young.) 
BreepinG Notes.—This species is common during the spring 
migrations and a goodly number stay during the summer. The 
female displays great courage and feigns helplessness and distress, 
to the utmost degree, when one is near her nest. A nest found 
July 21st contained three nearly fresh eggs. It was placed two 
feet up in a small beech bush, well built into the fork of small 
limbs and was composed of rottengwood fibres, cocoon silk, and 
scantily lined with white horse hair. (W. H. Moore.) A nest 
with young birds was found on the 4th August, 1902, in a wood 
near Lake Nominingue, about 100 miles north of Ottawa. It was 
built in a raspberry bush and made of grass and a few leaves, 
lined with hairlike roots; nest 3 x 2 and 2 x 1:25. (Garneau.) On 
the afternoon of June 5, 1886, when out in a tract of low,thick under- 
wood,about a mile to the west of Wildwood, I found a nest with one 
egg, which at first I took to be one of a chestnut-sided warbler, so 
much did it resemble the nest of that species in form, size, mate- 
rials of composition and situation. The egg also had a much 
similar appearance, but the different notes of the female owner 
of this nest soon attracted my attention, and I waited, a short 
time till she came out of the thick foliage where she was con- 
cealed and approached the more open space where I was standing, 
then I saw that she was quite a different species, and a more 
close examination of the nest showed that it was a more com- 
pactly formed structure than is usually made by the chestnut- 
sided bird, though the eggs of both species are much similar.
