THE BIRDS OF WISCONSIN. 
King records the capture of specimens at Waupaca, July 
22, 1876 (1). 
Morula migratoria (Linn.). AMERICAN ROBIN. 
An abundant summer resident, arriving early in March, or 
even the last of February, and remaining until the middle of 
November. Nests may sometimes be seen with the full com- 
plement of eggs as early as May 1, before a leaf has appeared 
on the tree in which they are placed, and young from the nest 
are not infrequent as early as May 25. The robin is, rarely, 
found in the dead of winter in southern Wisconsin. 
Sialia sialis (Linn.). BLUEBIRD. 
The bluebird was formerly a very abundant summer resi- 
dent, but the birds which annually visited Wisconsin seem to 
have suffered as severely from the general southern freeze of 
a few years ago as those of other parts of their range. During 
the summers of 1895 and 1896 they were almost wholly 
absent, but in 1897 they appeared to be slowly gaining in 
numbers, and have continued steadily to increase, until now 
they can be classed as common summer res'dents again. 
Doubtless the day is not far distant when they will havt 
regained their former numbers. One of the first of the real 
migrants to appear in spring, the date of the first arrival, of 
course, depending entirely on the season. They often are here 
by the first week in March, but it is sometimes well along in 
the month before the first one puts in an appearance. They 
remain in the fall until about November 1. Probably no bird 
in Wisconsin has been so persecuted in its nesting places by 
the English sparrow as has this species. Formerly a common 
resident of the towns and villages, nesting anywhere within 
a few feet of, or even about the buildings, it has been almost 
entirely driven to the country by this miserable pest.
