Prepare Your Data for Listers Corner

Lister's Corner

Lister’s Corner

Since we’ve officially hit December, it’s time to start thinking about gathering your data for your submissions to the 2017 IOS Listers Corner! As always, you may submit in any manner you choose, be it email to Joe Lill, sending Word docs or Excel files, or by snail mail to:

Joe Lill
5736 N. Avondale
Chicago, IL 60631

All tallies should be as of the end of 2017, so my email should start to fill up on January 1st. We can’t wait!

Since the American Ornithological Society (AOS) issued its 58th Supplement to its Check-list of North American Birds in which Thayer’s Gull was relegated to a subspecies of Iceland Gull, there have been a number of questions from the Illinois birding community about the handling of Thayer’s Gull with regards to list submissions. The Listers Corner Committee (with the approval of the IOS Board) will be handling the Thayer’s Gull question in this manner:

  1. Thayer’s Gull will be countable for all 2017 year lists (state, county, etc.). Technically, one shouldn’t count it if it is first found after July, when the IOS Records Committee amended the official state list. See the official Illinois State List of Birds on the IOS Web site.
  2. Thayer’s Gull will be countable for all Big Days and Big Months through July 2017, but not afterwards.
  3. Thayer’s Gull should not be included with any submitted life lists (state, regional, county, sites, buddy, etc.). This pertains to any total submitted for inclusion in the 2017 Listers Corner.
  4. The Listers Corner Committee will not be going back and vetting any lists from the past. Even though we know for certain that some birders have Thayer’s on their lists, it would be impossible to apply retroactive adjustments in any kind of equitable manner. If a birder does not submit an updated number, the number on record will not be changed.

If you’re new to the listing game, or need a refresher, please check out the 2016 lists at Listers Corner on the IOS Web site. You’ll see quite a number of lists. Feel free to submit to one or dozens! You do not need to be a member of IOS is order to participate, but we encourage you to become an IOS member.

The deadline for submission is January 31, 2018. So, don’t wait. Send in your 2017 data and check it off your list.

Questions? Please don’t hesitate to shoot us an email. We are already starting to receive submissions from some who will be out of the state for the duration of the year.
