THE WILSON BULLETIN— December, 1922 
invariably betray her home. It is easier still to locate the 
“ house " if the birds are building, as in the case of the Blue-gray 
Gnatcateher, for the birds keep their territory pretty will cleared 
of intruding visitors. On one occasion the female Ruby-throat 
left her nest repeatedly to torment a family of Carolina Wrens, 
and to pay her respects to a Tufted Titmouse. Otherwise I 
think I should have never located the tiny nest situated 50 feet 
t/ 
above ground, and so thoroughly concealed from view. 
With us it would seem that the nesting site most preferred is 
one over-arched by some large protecting limb, and below the 
nest there is generally another heavy limb which makes con- 
cealment the more complete. The nest is thus placed on a limb 
protected from the sun above, and observation below, and singu- 
larly enough these protecting limbs are such that the wind 
seldom lashes them against the limb on which the nest is 
saddled. 
SCISSOR-TAI LED FLYCATCHER ( MuSCivOVd forfiCClta) 
This species can now be definitely reported as a rather com- 
mon Summer resident in Western Arkansas. However its range 
is limited to the small prairies of Sebastian and Crawford coun- 
ties, and parts of Franklin county. It has not failed to nest 
almost in the heart of Fort Smith for many vears, and it was 
my good fortune to observe several pairs of these birds on the 
edge of the city during the week of August 13-19, 1922. Whether 
the bird has established itself further inland along the western 
tier of counties is not yet known, but it is certainly not found 
north of Fort Smith.
