Big Atlas Weekend 2021 was a success! All four participating Atlas projects had great turnout the weekend of June 25-27. By now, many atlasers have figured out that the best atlasing period is late June through early July, which is why we’ve started this annual mid-summer competition. It was a great time to be out with lots of babies hatching and needing to be fed.

Despite the hot, muggy weather here in ME, 206 atlasers participated! Of the 229 species that have been confirmed breeding in the state to date, 199 of them were documented over the weekend, including 24 coded species seen in ME and nowhere else.

Achievements in ME

Maine atlasers are absolutely amazing! This is the third Atlas in the state, and a lot of experienced atlasers are putting their skills to work while many others are just getting hooked. Here are some of the achievements from the first Big Atlas Weekend.

Participation by Atlas Project

When we look at all the states combined, we had a bevy of 1001 atlasers out in all four participating areas who spent a total of 3276 hours making 6169 confirmations! These are impressive numbers considering this was the first ever Big Atlas Weekend!

Everyone who participated received a free introductory bird identification course from the Bird Academy at the Cornell Lab of Ornithology.

Despite Maine having lower counts in many categories, our atlasers were incredibly efficient, and when we compared effort across states and adjusted for the number of atlasers and the geographic size of each state, Maine came out the overall winner.

Next Year

The Big Atlas Weekend coordinators had a great time organizing this year’s event, so much so, that we’ve already started discussing the details for 2022. We hope to expand to other Atlas projects since this year was such a success.

Mainers will need to defend our title in our final year of atlasing!
