THE WILSON BULLETIN— June, 1922 
as I knocked, and flying immediately she recognized her caller. 
Fresh chips on the groniid first attracted my attention. The 
contents of this nest was never ascertained, as to do so would 
liave necessitated destroying the site. On the evening of May 
15, over a montli later, the Richardsons, Mr. Laws, and I vis- 
ited the nest again. Dr. Richardson hoping to secure Graflex 
])ictnres of the Avoodpecker leaving the hole. This time the 
male Avas in the cavity, and pound the tree as Ave Avonld at 
the base, we could not drive him out. At every hard knock his 
head Avonld bob out an inch or so, as if driven by the force of 
the bloAV. He was only induced to leave Avhen I climbed half 
Avay up and drove him out an inch at a time by repeated ham- 
mering I I 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 shoAvs his red head, by so-called sportsmen. No true sports- 
man Avonld Avantonly kill such a picturesque and beneficial 
creature. 
Empidonax vircscens (Acadian Flycatcher). — Hardly as 
[dentifnl in the Baraboo Blntts as in 1913, Avlieii many pairs 
nested near the lieadAvaters of Otter Creek. Tavo examples Avere 
collected here, hoAvever, and a number seen and heard. A typ- 
ical nest and four heavily incubated eggs AA^ere found June 12. 
This species is probabl}" not as rare in southern Wisconsin as 
formerly supposed. Tavo or three pair Avere noted in a tama- 
rack SAvamp at Calhoun, Waukesha County, on Jime 26. 
Corvus h. hracdiyrhpnclios (CroAV). — This abundant rascal 
is only included because of a point of special interest. Winter 
roosts of the CroAv are Avell knoAvn and have been frequently 
described, but I have been unable to find any records of sum- 
mer roosts. Approximately five hundred CroAvs roosted in the 
Sank City cemetery and across the road in evergreens sur- 
rounding an unused house. This daily gathering Avas 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 nndiniinished numbers up to the time of onr departure, June 
13. They straggled in from all points of the compass about 
snndoAvn, 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 mnch cawing and general crow- 
racket. At first I had assumed that tiiese were non-breeding
