Cowbird eggs or young are found in many if not most of the nests of 
small species found here. They should be thinned out. 
123. Agelaius phoeniceus phoeniceus, Red-winged Blackbird. A com- 
mon summer resident. They arrive the first and second week in March 
and some stay late into November. 
124. Sturnella magna magna, Meadowlark. A common summer resi- 
dent in the same places as the Bobolink. We saw one at Mineral Springs 
March 11, 1916. Mr. H. K. Coale asserts that the form breeding in 
Indiana and Illincis is Siurnella magna argutula, Southern Meadowlark, 
which is probably correct. 
125. Icterus galbula, Baltimore Oriole. A moderately common sum- 
mer resident. 
126. Euphagus carolinus, Rusty Blackbird. A migrant of somewhat 
uncertain behavior in regard to time and appearance. 
127. Quiscalus quiscalus aeneus, Bronzed Grackle. An abundant mi- 
grant, but not very common as breeder. Arrives at the same time as 
the Redwing and is found late into fall. 
128. Hesperiphona vespertina vespertina, Evening Grosbeak. This 
rare, erratic northern visitant now turns out to be a very common win- 
ter resident in the Dunes. They were first discovered by Mr. Stoddard, 
February 6, 1916, along the Calumet between Gary and Millers, making 
their quarters in a densely grown ravine on the north side of the river. 
At first a flock of about forty-five was seen, then we saw small flocks 
at Mineral Springs on March 11 and 18; March 30, flocks of seventy-five 
and fifty were seen. Then more and more disappeared, until May 4 the 
last one was seen. They reappeared in the same places, but not so 
many, in November of the same year, 1916, and were seen now and then 
also in Chicago till the last week in May, when Mr. H. K. Coale saw 
one in Highland Park. We saw small flocks of six to eight March 24, 
1917, at Mineral Springs, and Stoddard took one there May 15. 
The reason for this preference for the Dunes became apparent when 
I examined the stomach contents of several taken; this consisted mostly 
of the berries of Rhus trilobata, Rhus aromatica, and even Towicoden- 
dron vernix. The first two are extremely abundant near Millers, the 
last at Mineral Springs. November 30, 1918, I saw about eighteen at 
Millers, and again December 21st and 28th. 
129. Pinicola enucleator leucwra, Pine Grosbeak. <A rare, irregular 
winter visitant. I took one out of two seen November 30, 1918. 
130. Carpodacus purpureus purpureus, Purple Finch. Another most 
erratic visitant, only with this difference that it may also be seen in 
summer. We have not found it often in the Dunes. April 1, 1916, we 
saw two near Gary, and January 6, 1917, there was a solitary one in 
the big timber at Mineral Springs.
