lowing the “breaking ploughs/’ picking up the grubs and 
worms as they are turned up by the plough-share. 
10. Bonaparte's Guee {Lams Philadelphia ). 
Similar to the last in size and general appearance. A 
migrant, spring and fall, breeding in the far north. Often 
seen in great flocks late in the fall. 
11. Caspian Tern {Sterna caspia). 
To be looked for as an uncommon migrant. 
12. Forster’s Tern {Sterna forsteri ). 
A summer species, breeding in the sloughs and marshy 
ponds in company with Black Terns. This bird with its 
black cap, pearl gray mantle, long forked tail, and snowy 
white under parts, well merits the name of “Sea Swal¬ 
low,” sometimes applied to the Terns. 
The Common and Least Terns may occasionally occur 
but are imperfectly known as Minnesota birds. 
13. Brack Tern {Hydrochelidon nigra surinamensis ). 
An abundant and, in the breeding season, noisy bird, nest¬ 
ing everywhere in sloughs and wet marshes. It constructs 
a rather neat but frail nest of fine stems on floating 
vegetation and lays from two to four dark, spotted, strong¬ 
ly pyriform eggs, similar in appearance to those of most 
Terns. The black body-plumage of the adult bird ren¬ 
ders it very unlike its snow-white relatives, in appearance. 
14. DoubrE-crested Cormorant, “Black L0011” {Phalacrocorax 
dilophus). 
A common bird, congregating in certain localities where 
they build their nests in the tops of trees or on the ground, 
usually on islands in large lakes. It has rapidly decreased 
in numbers of late years. Cormorant Lake in the south¬ 
western part of the County derived its name from the 
presence in former years of a colony of these birds. 
15. White Perican {Pelecanus erythrorhynchos ). 
This large bird,—formerly abundant, nesting on the 
ground in colonies,—is now greatly reduced in numbers, 
occurring chiefly in small wandering companies. 
16. American Merganser, Sheldrake, ( Merganser americanus). 
Probably appears chiefly as a migrant spring and fall.
