As the About page of this blog states, I like searching for uncommon birds in my area. Like this past weekend when I found a second spot for BOBOLINK in Johnson County. The other known spot being at Atterbury FWA.
Back in December I posted about the loss of grassland area at the corner of I-65 and County Line Road. Well the field is still grassland and there is no sign of development. So Sunday I checked the field to see if DICKCISSEL had returned. Dickcissel were present along with calling GRASSHOPPER SPARROWS.
But the big surprise were Bobolink.
I remember even though we were farther north in Illinois Bobolink were uncommon because of lack of grasslands in our agriculture county. Thus I had very few photos from Illinois.
In Illinois I used to take an annual trip to Midewin National Tallgrass Prairie to see Bobolink, Upland Sandpiper, and Loggerhead Shrike. And for the record on the last couple of visits the Upland Sandpiper weren’t present.
The question now is will the owners of the local grasslands cut the grass so the Bobolink have to leave? The Bobolink Field at Atterbury is usually cut in early June for hay. It wasn’t cut until August a couple of years ago and they stayed the entire summer.
The good news is according to The Birds of North America Online the average egg date is May 20 with 12 days of incubation. And if undisturbed the young leave the nest in 11 days. If that holds true then the young are gone around mid-June.
I’ll monitor both fields and hope the grass isn’t cut until late June.
