Hi Betsy, Red Crossbills breed early in the year and are often on the move by mid-late summer. The timing doesn't say much as to what winter will bring but the recent occurrence of several western types here indicates an influx from that region in the short term no doubt. Pine siskins were around in above average numbers in mid-summer but their numbers have already subsided it seems. I haven't noted any unusual patterns in numbers of Red-breasted Nuthatches or other boreal species at this point. Typically, irruptions of winter species like redpolls, white-winged crossbills, waxwings, evening and pine grosbeaks don't show themselves until mid-late October into November. We shall see!

Ryan, do you think that your report (among others) in the last few weeks noting northern species like red breasted nuthatches, crossbills and more, suggests a possible eruption year? Having followed the spring and summer of substantial rains in the north, I would have thought that the food supply would be substantial at the least. Any thoughts on this? Betsy Abert

Types 2, 3, 4, 5, and 10 have all been recorded this week alone. Type 4 is rather rare in the east. Moreover, my recording of a Type 5 on Sunday marks the first known state record and only second known record east of the Mississippi. Learn more about the types and how to help document them (it's easy!) in this new Wisconsin eBird story. Thank you!
