30. Butoricles virescens (Linn. ). 
Green Heron. A snmmer resident, 
known at least to breed just out- 
side town limits. A bird remained 
at Hall's pond from June 1 to 19, 
1897, and one was again seen there 
on May 17, 1902, though they do not 
breed about the pond. May 6 to 
31. Ardetta exilis (Gmel. ). Least 
Bittern. Formerly a summer resi- 
dent, Defore Leverett pond was 
claimed by the park system. 
According to Mr. W. P. Hender- 
son it also formerly bred at Ham- 
mond's pond. 
82. Botaurus lentiginosus (Montag). 
American Bittern. An uncommon 
migrant, before Muddy river was 
improved much more common. 
May 10 to . 
33. -^x sponsa (Linn.). Wood Duck. 
Formerly a rare summer resident. 
Mr. N. A. Francis tells me that 
many years ago this species bred 
near Lost pond. 
34. Branta canadensis (Linn. ). Can- 
ada Goose. A not uncommon 
migrant. Of late years I have 
never heard of any alighting on 
Brookline ponds on their migra- 
tions. Mr. L. A. Shaw records a 
flock flving over Chestnut Hill on 
January 7, 1902. March 27 to 
April 27. to . 
35. Anas obscura (Gmel.). Black 
Duck. They formerly visited 
Lost pond occasionally, where 
there is to be seen an old duck 
blind, but until the present spring 
I have never observed them in 
numbers in the town. On April 
12th I flushed a pair from the 
Putterham meadows, and again 
on the 13th four birds. They may 
have bred. In the fens, however, 
they are often common in the 
autumn. 
36. Nettion carolinense (Gmel.). 
Green-winged Teal. One young 
male was shot by Mr. L. F. Fos- 
ter, September 25th, 1882, near 
the Brookline border. 
37. Querquedula discors (Linn.). 
Blue-winged Teal. Undoubtedly 
formerly not uncommon as a 
migrant. Mr. F. H. Allen saw a 
single bird on Weld pond on 
October 26, 1884.
