Big Atlas Weekend – June 24-26, 2022

If this year’s “Global Big Day” didn’t fit into your busy spring schedule, here’s another chance to make your birding count! How about a Big Atlas Weekend? This exciting annual event is a fun way for birders from across the province to document breeding birds and come together as a birding community. For many birds in our area, breeding peaks in late June. It’s a great time to confirm breeding and fill gaps in the Atlas dataset.
This event is being coordinated across the four US states and two Canadian provinces currently conducting breeding bird atlases: Newfoundland, Ontario, New York, Maine, Maryland and DC, and North Carolina.

June 22 @ 6 pm EDT – Kickoff. Introduction by the six Atlas coordinators followed by guest speaker Robyn Bailey, Project Leader at NestWatch.

Inter-Atlas Competition

Just to make this event even more exciting, the Atlas team has set up a friendly competition between the six participating projects: Newfoundland, Ontario, New York, Maine, Maryland and DC, and North Carolina. The winning project will receive the Big Atlas Weekend trophy and have their state or province engraved on the side. Maine took it home last year; who will get it this year??
The winning region will be selected based on its rank in each of 3 inter-region challenges (standardized across regions by the number of atlassers). The region with the highest cumulative rank will become the overall winner of the Big Atlas Weekend – and recipient of the trophy!
The inter-atlas challenges are:
- Nocturnal checklists
- Number of nocturnal checklists submitted during the event in each region
- Breeding codes
- Total number of breeding codes submitted during the event in each region
- New-to-user squares
- Percent of atlassers in each region who submit an atlassing checklist during the event in a block they have not personally atlassed in before
