Someone put up a ton of bird feeders at work which may seem odd for most, however, working for a institution, specifically one that is the 'guardian and recorder of the biological resources of Illinois', we have many bird-watchers.
Since putting up these feeders, there are birds galore outside and evidently, not just the typical bird, but some rare birds, not typically found outside our windows. Freqently these days, people can be found standing at the window, binoculars in one hand and birder's guide in the other.

I have no idea what birds these happen to be, but thought I'd try to catch a photo or two. I didn't have the correct lens to get a great close-up, but thought I'd try & see what I could get. Better luck next time!
