Aaron Yetter’s newest weblog off the weekly aerial waterfowl survey for the Illinois Pure Historical past Survey notes much more geese hung round, even with the ice, than he anticipated. I believe he requested an attention-grabbing query on whether or not they are going to nonetheless be right here subsequent week when the warmup comes.
As regular, there have been nuggets. For me, it was on goldeneyes.

December threerd, 2020 – Aerial Waterfowl Stock Weblog
We waited till Wednesday of this week (December 2nd) to fly the waterfowl survey. The climate seemed good so we determined to see what the chilly snap would do to duck numbers. I feared many of the geese would get out of right here with the 20o F low temps on Monday and Tuesday. Boy was I fallacious! We had numerous ice on Wednesday morning, however the geese stayed. In truth, we noticed extra geese than earlier than Thanksgiving alongside each rivers. I’m certain we had some new geese arrive with the chilly climate and north winds, as evidenced by the growing variety of mallards and customary goldeneye (generally often known as whistlers or ice geese). And we had another divers (primarily lesser scaup) take off for hotter climates. The departure of scaup was additionally obvious in our band return knowledge from geese that we leg band throughout spring round Havana, IL and Pool 19 of the Mississippi River. Our weekly band return report from the Chook Banding Lab indicated the lesser scaup are undoubtedly in Louisiana and Texas with a number of bands being reported from the deep south.
This week we noticed ~423,000 geese alongside the Illinois River and ~830,000 geese on the central Mississippi River. These numbers are effectively above common for the primary week of December and seven% larger than final week alongside the Illinois River and 25% greater than final week on the central Mississippi. As soon as once more mallards had been essentially the most quite a few species with virtually a half one million mallards alongside the central Mississippi River and effectively over 1 / 4 million on the Illinois River. I do know many duck hunters in Illinois are going to doubt these numbers as a result of searching success has been poor for essentially the most half, however we took a number of pictures to indicate how they hunkered down and stored pockets of water from freezing within the cool temps. I assume we’ll see subsequent week once we heat up and thaw if the geese continued to stay round.
