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 state 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 four states and two provinces that are currently conducting breeding bird atlases—NewfoundlandOntarioNew YorkMaineMaryland 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. Robyn will be talking about how the data NestWatch collects both complement and differ from atlas data, what kinds of questions NestWatch is answering with those data, and best practices for making high-quality observations on nesting birds.
  • June 24-26 – Big Atlas Weekend! Go atlasing in any of the six participating regions from 6 pm EDT on Friday to 11:59 pm EDT on Sunday.
  • June 29 @ 6 pm EDT – Awards ceremony. Enjoy highlights from the weekend, share your stories in small groups with atlasers from all regions, and find out who won the individual and state champion awards.
