Illinois Field Notes — Spring, 1961 
By Mrs. Vinnie T. Dyke 
THE WEEK OF APRIL 30TH my husband and I hurried to a farm near the 
shore of the Illinois River not far from Bureau Junction to investigate re- 
ports of a “new” heron. We observed a Cattle Egret, the first one reported 
in Bureau county. Mrs. Alba Miller was first to see the bird. Her neigh- 
bors, Mr. and Mrs. Einer Swensen, had the heron walking about their barn- 
yard among the livestock. 
The spraying for Dutch Elm disease has had its usual deadly aftermath 
and so far we have been unable to stop the slaughter. My own records of 
fatalities include a Hermit Thrush, Golden-crowned Kinglet, two Cedar 
Waxwings, and a dozen or more Robins.

WE HAVE SEEN quite a few hawks all winter; on January 11 we counted 
five Marsh Hawks, two Sparrow Hawks, and one Rough-legged near De- 
catur. On March 11 we saw three Gadwalls near Rea bridge, about six 
miles from town. Frank Irwin reported five Canvasbacks; they have been 
rare here. March 15, near Lost. bridge, we saw two Horned Grebes. On 
March 238 Frank Irwin reported four Eared Grebes; we confirmed the 
identification the next day. On March 25 Mrs. Nearing and I saw our first- 
of-the season Green-winged Teal, and this completed our list of all the 
ducks normally seen in Illinois each winter. 
With a few of the Champaign birders we traveled to Enos, Indiana on 
March 26 to look for Prairie Chickens. We found just one perched in a tree. 
The custodian at Willow Slough Reserve said he had canvassed the area the 
day before and had found only six of the species. This is the worst report 
in years. On April 4 we saw two Hooded Mergansers on the lake. On April 
21 Mrs. Nearing and I found two Worm-eating Warblers in a brush-pile 
near the river at South Edward Street; nearby were two Prothonotary 
Warblers. We took several pictures.
