Sept 21, 2015
Tonight all of Illinois, except for, strangely, the northwestern region, is receiving fairly uniform light migration. The current national composite radar (http://tempest.aos.wisc.edu/radar/us3comp.gif) is also detecting some patchy areas of moderate migration in the southern regions of the state tonight.
Tomorrow night should bring very similar conditions; southerly winds over the northern half of the state will likely contribute to little migration there while northernly winds in the southern half may cause some movement in the southern half of Illinois.
I certainly noticed some turnover today. On my Oak Park Bird Walk, characteristic late-migration species such as Yellow-bellied Sapsucker and Yellow-rumped Warbler were detected for the first time in my neighborhood this fall.
Liz Day Shorebird Forecast: Nothing really new in this department as we are nearing the end of shorebird migration. Keep checking Lake Michigan as well as inland locations like Emiquon and Chautauqua, etc. Due to shorebird migration diminishing over much of the state, I am going to stop doing these mini shorebird reports until next spring starting in about a week or so.
To predict exactly which species you are likely to see and when, please consult:
