WHITE-BELLIED SWALLOW. 65 
specimens. I believe I again saw this swift at 
Fort Colville. 
In June I observed a very large number of 
swifts in company with about an equal num- 
ber of goatsuckers (Chordeiles popetue); they 
were hovering at a great altitude. After wait- 
ing a very long time, I succeeded in obtain- 
ing one goatsucker. The swifts never came 
within shot; neither did I ever after see them. 
On opening the goatsucker, its stomach was 
perfectly gorged with winged ants. I have no 
doubt this was the attraction which delayed the 
swifts on their northern route; and from the 
fact of their disappearing here, as they did at 
Sumass, I imagine they go far north to nest; 
had they bred anywhere along the Boundary- 
line, I am sure I must have discovered them. 
White-bellied Swallows (Hirundo bicolor) are 
always in great force, and make their nests of 
ducks’ feathers, in holes either bored by them- 
selves, or the work of woodpeckers, in the totter- 
ing old willows that grow round the oozy margin 
of the lake. Flycatchers, sedgebirds, and a 
host of other summer migrants, specified in the 
Appendix, take up their respective hunting- 
grounds, and commence domestic duties.
