THE WILSON BULLETIN— June, 1922 
Eatlier common locally in Sauk Comity, around the sandy, 
grassy fields at the foot and part way up the sides of bluffs. 
Small colonies Avere seen on the bald tops of certain high 
bluffs in Columbia County, in grass and Aveed patches, near the 
graA^elly spots where the Nighthawks lay their eggs. In the 
toAAmship of Mazomanie, Dane County, a small colony has been 
located for years on a bit of AAmste land a short distance from 
the river. In a general way it may be said to be partial to 
sandy or barren spots groAvn up to short grass or weeds in 
places that are seldom plowed. 
Zonotrichia 1. leucophrys (White-croAvned SparroAv). — An 
adult female taken in the Baraboo Bluffs, Sauk County, June 
0, suggests the possibility of their breeding here. 
^pizcv americana (Dickcissel) . — A great Dickcissel year in 
all parts of southern Wisconsin visited. Biding along the coun- 
try roads, singing males were noted as averaging six to ten to 
the mile. In many of the hay fields they were the commonest 
birds, at least three or four pair per acre. 
Seiurus motacilla (Louisiana Water-Thrush). — These shy, 
elusive creatures are regular migrants in small numbers along 
the Wisconsin Elver valley, and a feAV pairs breed near the 
source of Otter Creek, a rushing trout brook in the Baraboo 
Bluffs. June 27, 1913, a nest Avith one egg was found, in a 
pocket in the bank of the brook. A feAV days later, finding it 
deserted, it was collected, as well as an adult of this species 
that frequented the vicinity. This spring (1921) I made a 
special effort to get a satisfactory breeding record, but the 
nearest I came to it Avas finding a pair June 6 feeding a big 
lubberly Cowbird. The female parent was collected for identi- 
fication. 
An early record is a specimen collected in the river bottoms in 
Sauk County April 17, the day after the blizzard. The bird Avas 
in the snoAv by a slushy pool. Although there were four or five 
inches of snow on the ground, S. Paul Jones and the writer 
listed fifty species of birds in these sheltered bottoms. This 
disastrous storm must have destroyed every Woodcock and 
Prarie Horned Lark nest in the southern counties of Wisconsin. 
Thryomanes h. heivickii (BeAvicks Wren). — At least two 
pairs of these wrens appeared in the vicinity of Prairie du Sac 
this last spring (1921) and 1 tried without success to collect 
a specimen to establish a clear record for the State. My friend, 
Mr. Albert Gastrow, told me of a species of Avren neAV to him
