continually in large numbers over woods and swamps, where a 
great many must surely have nests. Just south of the house 
there are a quantity of old dead trees broken off high up. One 
can see that they are open at the top, and they are probably 
hollow throughout. I often saw individuals fly down into these 
trunks, and there was always a company circling over that 
place. Unfortunately I had do opportunity to examine the in¬ 
side of the trunks. They have nests very commonly in unused 
chimneys, but the pair that bred with us had a nest in the 
garret on the outside of the chimney. In 1882 it seemed for a 
long while that they would not build. Three flew constantly 
together out and in; but at last the nest was built and the first 
egg was laid July 1. In 1883 the first egg was laid June 
16. Both times there were five eggs in the nest; but when 
the young became larger there was not room for more than two, so 
the others had to cling with their claws to the chimney above 
the nest. This gave occasion for continual quarrels and scenes.

the swamps where it is seen oftener than in the woods. In 
1882 there was a pair that had a nest on a branch of a maple 
tree, twenty-six feet over one of the old beds of Wolf River. 
The birds appeared to be still building June 21. July 18, 1883, 
and later, I saw a female take small insects -— perhaps for the 
young — in a spider’s web at the house. In 1882 two were 
seen May 9. Afterwards none before the 16th. Then frequently 
till Aug. 20. In 1883 they were present in much larger num¬ 
bers. The first was seen May 17. Afterwards daily. Often- 
est single. June 11, however, I saw five that appeared to be 
in company. They hovered round our blooming plum-trees. 
82. TyrailllllS tyraillllis (Linn.). XX In 1882 two were 
seen flying April 30. A single one May 8. The day after, many. 
None 11th, 13th and 14th, but otherwise daily. Hardly seen 
after August 23. In 1883, the first May 7. 13th many. Builds 
mostly over water, not in deep woods, but in the open places, 
in meadows and near farms, in an isolated tree or a large bush. 
In 1882 there was a pair at least at every farm. In 1883 this
