Plegadis guarauna (LINN.) RipGw. 1878. 
Found as a rare straggler in British Columbia. Only two speci- 
mens known to have been taken in that province; one on Salt 
Spring island in the Gulf*of Georgia, and the other at the mouth of 
the Fraser river. (Fannin.)

Botaurus lentuginosus (MONTAG.) STEPH. 1819. 
This species is only a straggler in Greenland but is a summer 
migrant in Newfoundland and Labrador. It breeds in Prince 
Edward Island, Nova Scotia, New Brunswick, Quebec and Ontario 
and northward to Hudson bay, in all suitable localities. 
Westward it becomes more abundant and is found commonly 
from Manitoba to the Pacific, never being seen in flocks but turning 
up in all marshes and in weedy brooks. Spreadborough found it 
in many of the marshes between Lesser Slave lake and Peace River 
Landing, Atha. Richardson says it is common in the interior up 
to the fifty-eighth parallel, and Bernard Ross says it descends the 
Mackenzie to the Arctic sea. Although it is abundant and breeds 
in British Columbia we have no record of its occurrence in Alaska. 
BREEDING NoTES.—A pair breeds every year in Ashbridge bay, 
Toronto, Ont. This species lays five eggs, occasionally six. (Razne.) 
Breeds in the marsh on the north side of McKay lake, Ottawa and 
in the marsh at the Experimental Farm. (W. T. Macoun.) Two 
nests were found by me near Ottawa hidden in weeds near marshes. 
The nests were flat, made of reeds and measured eleven inches in 
diameter. (Garneau.) 
I have found the nest of this species four times in the county of 
Leeds, Ont. The bird lays its eggs very regularly about the 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
