Oct 2, 2015

Hello birding friends,

Tonight, Illinois is experiencing very uniform moderate migration, meaning that tomorrow morning would be about as good as any to get out and start seeing some of those mid-to-late migration species, depending upon where you are in the state. Although Illinois is certainly experiencing northerly tailwinds (as we've also recently seen from the recent drop in temperatures), tonight the winds are just a bit too strong in northern Illinois for huge quantities of birds to be migrating through, as can be seen on the current national composite radar ( - note that radar noise in southern Illinois is accordingly a tad stronger than that in more northern regions.

With almost exactly identical wind conditions tomorrow night, Saturday morning also looks like it should be moderately productive with some nice turnover. Speaking of turnover, my predicted wave of Hermit Thrushes has arrived in the Northern parts of Illinois! This turnover is also evident in other species such as both Kinglets moving through northern Illinois profusely, warblers like Black-throated Green and Blackpoll starting to retreat to only the southern portions of the state, and even raptors such as Accipiters and Peregrine Falcons are on the move now! To predict exactly which species you are likely to find and when, please consult these helpful resources:

So in summary, both tomorrow (Friday) and Saturday mornings should be fairly productive with regards to avian arrivals and influxes.

Good birding,
