where they are said to breed twice a year, in the months of April and 
June; I have not noticed the purple martin breeding in any other 
place within the city, but I dare say they do breed in other yards 
where they are encouraged to nest. (Wzntle.) At Ottawa this 
species builds in holes in trees or in boxes in the city: The nest is 
composed of hay, straw, bits of twine and paper; lined with feathers; 
eggs, four or five, pure glossy white. (G. R. White.) Breeds all 
over central and western Ontario, making its nests in holes under the 
eaves of buildings; in the vicinity of Yorkton it makes its nest in 
holes in trees like the tree swallow; on June 1st, 1901, I found a pur- 
ple martin sitting on five eggs in a hole in an old stub five feet from 
the ground; the bird allowed me to lift her off the eggs and I threw 
her into the air and she flew away; the following day I again found 
her sitting upon the eggs; later I found other nests around Crescent 
lake. (W. Raine.)
