SPRING DUCKS. 
The spring is a period of comparatively little interest 
at Wenham. Both Golden-eye and American Mergansers 
are common, increasingly so on account of the stopping 
of spring shooting, and their display activities can often be 
seen. Nearly all other species, except the Black Duck, are 
practically absent, and even this last is seldom seen on the 
open Lake, because in March and April the river marshes 
are covered with water and there is plenty of more attrac¬ 
tive ground. 
OTHER WATER BIRDS AT WENHAM LAKE. 
Grebes. 
Holbcell’s Grebe is a rare visitor to the Lake, the Horned 
Grebe is uncommon but not rare, and the Pied-billed is very 
common. 
Loons. 
The Loon is very commonly seen flying over at a great 
height during late September and early October, crossing 
Cape Ann in a general northeast to southwest direction. 
A few come to the Lake. During the past two summers a 
single Loon has remained in the Lake for a considerable 
period, something that was never noted before. The Red- 
throated Loon has only come to the Lake a few times, and 
one or two have been shot. 
Gulls. 
The Great Black-back is extremely rare at Wenham, the 
Herring Gull very plentiful, while the Common Tern has 
been seen only once, as nearly as I can remember. 
Petrels. 
Leach’s Petrel has been taken once and seen two or three 
times. '
