THE WILSON BULLETIN— June, 1922 
as I knocked, and flying immediately she recognized her caller. 
Fresh chips on the ground flrst attracted my attention. The 
contents of this nest was never ascertained, as to do so would 
have necessitated destroving the site. On the evening of May 
15, over a month later, the Richardsons, Mr. Laws, and I vis- 
ited the nest again, Dr. Richardson hoping to secure Ctraflex 
pictures of the woodpecker leaving the hole. This time the 
male was in the cavity, and pound the tree as we would at 
the base, we could not drive him out. At every hard knock his 
head would bob out an inch or so, as if driven by the force of 
the blow, lie was only induced to leave when I climbed half 
way up and drove him out an inch at a time by repeated ham- 
mering! T firmly believe that the scarcity of these fine birds 
over a large part of their former range that is still suited to 
their requirements, is directly due to the shooting of every one 
that shows his red head, by so-called sportsmen. No true sports- 
man would wantonly kill such a picturesque and beneficial 
creatu re. 
Empidonax vircscens (Acadian Flycatcher). — Hardly as 
plentiful in 1 lie Baraboo Bluffs as in 1913, when many pairs 
nested near the headwaters of Otter Creek. Two examples were 
collected here, however, and a number seen and heard. A typ- 
ical nest and four heavily incubated eggs were found June lA 
This species is probably not as rare in southern Wisconsin as 
formerly supposed. Two or three pair were noted in a tama- 
rack swamp at Calhoun, Waukesha County, on June 2(>. 
Corvu.s b. brachyrhynchos (Crow). — This abundant rascal 
is only included because of a point of special interest. Winter 
roosts of the Crow are well known and have been frequently 
described, but 1 have been unable to find any records of sum- 
mer roosts. Approximately live hundred Crows roosted in the 
Sauk Citv cemetery and across the road in evergreens sur- 
rounding an unused house. This daily gathering was first no- 
ticed by me on April 20, the first time I happened to be in the 
vicinity in the evening, and the birds still frequented the roost 
in undiminished numbers up to the time of our departure, June 
13. They straggled in from all points of the compass about 
sundown, sometimes alighting in a mass in neighboring fields, 
or perhaps sitting around in the trees having a good time gen- 
erally till roosting time. Soon after daylight they vacated the 
roost and left the vicinity with much cawing and general crow- 
racket. At first I had assumed that these were non-breeding
