40 ILLINOIS AUDUBON BULLETIN 
were not answered include: are there nesting populations of Black-and-white Warblers, 
Golden-winged Warblers, Nashville Warblers, Chestnut-sided Warblers and/or Mourning 
Warblers; how many locations are used by nesting Pine Warblers and in what density do the 
birds occur; what is the breeding distribution of Worm-eating, Prairie and Hooded War- 
blers; and how common or scarce are the other species? 
BLACKBIRDS, ORIOLES and TANAGERS. Who knows the breeding distribution of 
Bobolinks? How successful were Yellow-headed Blackbirds? There were three male Yel- 
low-headed Blackbirds in an E. Moline marsh all summer (E. Fawks); at least one young 
was banded there, 19 June (P. Petersen). Why were there so few Orchard Orioles reported? 
Did everyone find Northern Orioles to be common? There was a pair of Brewer’s Blackbirds 
in one Waukegan locality and two males in another (J. Neal) — hopefully this did not 
represent the sum total of the remaining Illinois population. We can probably guess why 
there were few grackles or cowbirds reported, but does that hold true also for the tanagers? 
GROSBEAKS, FINCHES and SPARROWS. Although the Rose-breasted Grosbeak is 
a rather common and conspicuous breeding species in much of the state, few notes were 
received. An immature male Blue Grosbeak was present at Lake Calumet from 20 June 
through at least 17 July (*C. Clark, et al.); seven birds (four males and three females) were 
found in Mason County, 26 June (D. Bohlen); the only birds reported from southern Illinois 
were observed on the Breeding Bird Surveys (V. Kleen). The only finch note of any kind 
was the attempted nesting of Red Crossbills in Springfield; three nests were built, 15 
March, 22 March and 13 April; however, none were successful (D. Bohlen). At Moraine 
View State Park it was interesting that one grassland (mostly forbs, redtop and bluegrass) 
supported nesting pairs or populations of Savannah, Henslow’s and Grasshopper sparrows 
but no Bobolinks while at nearby Parklands the grassland, primarily tall orchard grass, 
contained Bobolinks, but none of the sparrows (D. Birkenholz). Good numbers of nesting 
Grasshopper Sparrows were reported especially from McLean (D. Birkenholz), Vermilion 
(M. Campbell), Warren (L. McKeown), Sangamon (V. Kleen), St. Clair (J. Eades) and 
Washington (M. Morrison) counties. We need more information on breeding distribution 
and density of Henslow’s Sparrows. Summer records of Vesper Sparrows included: seven 
birds in Sangamon County (D. Bohlen); two in Hancock County, 5 June (V. Kleen); and 
“present” in Vermilion County (M. Campbell). 
As usual, all birders, regardless of affiliation, are encouraged to contribute notes for 
inclusion in the SEASONAL REPORTS, Please observe the following schedule:

“ For convenience of reporters, all records to be used in future seasonal reports, but 
occurring in earlier seasons (Ex., nesting Great Horned Owls found in March) can be 
reported along with the WINTER SEASON field notes you submit; however, these 
records will only be used in the BREEDING SEASON report. (Observers are encouraged 
to submit their field notes to the editor in advance of the deadline).
