24th of May apparently being little influenced by the season, 
just as in the case of the Loon. It also has a preference for 
the same locality year after year, even though the eggs are 
taken. The first three nests I found were in small ponds in 
a meadow nearly surrounded by woods, and were built three 
successive years in one or other of the two ponds among the 
flags of last year’s growth, in one case floating in two feet of 
water. The complement of five eggs, once of six, was laid by the 
26th of May, and in one case incubation had commenced some 
days previously. The fourth nest I found was in an open, but wet 
meadow, and the nest was formed of grass in a springy place, 
very unlike the others. Onthe 3rd of June the five eggs were 
much incubated. (Rev. C./. Young.) 
This species is rather common in the large marshes in western 
Ontario. It makes a bulky nest in a dry portion of the marsh 
and lays four or five eggs. (W. Saunders.) Breeding in large 
numbers at Crane Lake, Assa., in the marshes. The nest is gen- 
erally on old dead grass in one or two feet of water, but one con- 
taining two eggs partly incubated was found on dry ground on 
June 9th. On the 20th I found many nests but in nearly all the 
eggs were so much incubated that they were unfit to take. Most 
of the nests contained four or five eggs. One nest was taken 
which had five eggs in it, one of which was that of the Lesser 
Scaup. 
MUSEUM SPECIMENS. 
Two mounted specimens taken in Toronto marsh by Mr. 5S 
Herring. Three unmounted, one of which was taken at Ottawa 
by Mr. G. R. White, another at the same place by Dr. Charles 
Saunders, and another at Banff, Alberta, by Mr. Spreadborough. 
Several sets of eggs taken in the marshes around Cees Lake, 
between June oth and 16th, 1894. 
LXXI. ARDETTA Gray. 1842. 
191. Least Bittern. 
Ardetta exilis (GMEL.) GUNDL. 1856. 
A rare summer resident along the Bay of Fundy between Black 
River and Mispec, New Brunswick. (Chamberlain.) Accidental 
at Quebec. (Dionne.) Rare in the district of Montreal but per- 
haps more plentiful than we think, as it is retiring in its habits.
