BIRDS OF MINNESOTA 853 
the 15th of May. Its presence is easily noted, as the tail is ex- 
tremely forked, and it seeks the inside of barns and other out- 
houses to build its nest on the rafters and beams. Failing to 
find its favorite place to build, it will accept a place under the 
eaves like the Cliff Swallow, or not obtaining this, will go to 
the woods, and there select a hollow stub or tree so widely 
open that little else but the shell of the dry sappy part remains 
and will occupy it with ten to twenty or more nests. This out 
wardly, consists of mud brought in pellets and plastered to- 
gether with the saliva of the bird, into which is mixed a desir- 
able quantity of fine hay. When ithas assumed the right pro 
portions it is lined with fine grass, covered over which are loosely 
disposed feathers. It lays from four to five white eggs bear- 
ing a tint of fleshy roseate color, with fine dottings of two 
shades of brown, and reddish purple. Three broods are reared 
in a season oftentimes, but more frequently only two. In the 
early autumn they gather into flocks of considerable size, 
though not as large as in some other sections reported, and 
after staying a few days about the unfrequented streams and 
large marshes, disappear so suddenly that it is litthe wonder 
that our not very remote ancestors were led to believe that 
they hibernated in the marshes and swamps. In a country con 
sisting of so much treeless territory, it would not be expected 
to find the Barn Swallow universally distributed, but nowhere 
has it failed to be found where conditions favoring its incubat- 
ing habits have existed, or been subsequently developed. On 
the broad plains of the Red river valley, where barns are still 
the exceptions, I have found them in great numbers about a 
single out-house oftentimes. 
In common with all of the social swallows, they are every- 
where welcomed by the agriculturists, as their feeding habits 
do not levy upon the productions of man.
