inches, narrowing somewhat nearer the bottom. As soon as the nesting 
stubs were jarred, the young commenced their “ hissing ’’ noise, similar to 
young Flickers, but a great deal louder. 
10. Melanerpes carolinus. ReED-BELLIED WoopPEcKER.— This 
handsome species is a fairly common resident in certain favorable locali- 
ties, in the heavy bottom land timber along the Wisconsin River, and 
Honey Creek, in the same locality frequented by the Pileated Woodpeckers. 
Quite often observed in the village of Prairie du Sac, during the winter. 
A male and female and three partly feathered young were collected on the 
Dane County side of the river June 1, 1911. This nest was in a small 
and very hard dead limb of an elm tree, over a slough. The entrance 
hole was on the under side of the limb which extended from the tree at an 
angle of about forty-five degrees. 
11. Empidonax virescens. AcapiAN FLycatcHeR.— This species 
was found breeding in considerable numbers along small water courses 
in the Baraboo Bluffs in June and July, 1913. A series of nine adults and 
a number of nests collected. Was much pleased to find this bird breeding 
in this region as Kumlein and Hollister (Birds of Wisconsin Hypothetical 
List, 1903, p. 129) say of this species, ‘‘ We have never taken this species 
in Wisconsin, and all the observers with whom we have had correspond- 
ence, have also failed to find it. Hoy and some later writers include it 
in their lists, but evidently, without positive proof. The fact that Hoy 
appears to have been somewhat mixed on his flycatchers, as indeed many 
at that time were, and that all recent collections fail to produce a specimen, 
although furnishing both varieties of traillii, whereas Hoy included but 
one, of course, leads us to believe that a mistake has occurred, and so we 
await future developments.” 
12. Hesperiphona vespertina vespertina. HEvEnrInc GROSBEAK.— 
Have observed this species only during the winter of 1909, when they 
were quite common in the months of February and March, when a number 
of specimens were collected. The birds were observed to spend a great 
deal of time feeding on the winged seeds of the box-elder. 
13. Carpodacus purpureus purpureus. PurreLte FincuH.— Seen 
occasionally in spring and fall, but appears to be rather rare. One adult 
male collected from a flock of five or six that were feeding on Juniper 
berries, February 23, 1909. 
14. Bombycilla garrulus. BoHpmian Waxwina.— This species vis- 
ited Sauk County in large numbers in the winter of 1908-09. One flock 
estimated two hundred, seen March 1, and a number of specimens in high 
plumage were secured. 
15. Protonotaria citrea. PrRorHoNoTARY WARBLER. In the partly 
flooded river timber, on both the Sauk and Dane County sides of the 
Wisconsin River, this beautiful warbler breeds rather numerously in certain 
restricted areas. In two days, June 9 and 11, 1913, five nests were located 
containing eggs or newly hatched young; four of these nests being located 
in dead river birch stubs over water, and the fifth in a dead maple stump 
near a slough.
