“Sq. bash” is a time period that goes again to the primary Ontario Atlas (1981–1985). The “sq.” is the ten×10 km primary protection unit of the Atlas. The “bash” entails getting a gaggle of individuals collectively to make sure that under-sampled squares are adequately lined. Protection entails discovering as many species as doable breeding in every sq., watching the birds to watch proof of their breeding, and/or doing easy normal surveys known as “level counts”.

Collaborating within the Atlas-3 is a problem, a congenial solution to work with and get to know different birders, a straightforward solution to find out about a part of the province which may be new to you, and a significant contribution to the neighborhood science.

Even in the event you don’t discover the species you’re searching for, you’re nonetheless contributing beneficial knowledge.
We now have deliberate three sq. bashes for 2025. The occasions are:

It’s as much as you.
The occasions are led by Atlas employees, who assign duties and assist be certain everybody enjoys the method. There’s a get collectively across the campfire each night once we discuss concerning the day’s highlights and plan actions for the next day: who works with whom, the place, and what the particular objectives are. In some squares, canoeing or atlassing by bike are choices – no matter it takes and is of curiosity to you!

If you’re an skilled atlasser and know birds effectively by tune, you’ll be able to lead a small group engaged on a sq., and if not, you’ll be able to work with a extra skilled atlasser.
Some Atlas regional coordinators are holding their very own native sq. bashes.
Sq. bashes, together with this yr’s, are usually in poorly identified areas at far from main inhabitants centres, and, maybe due to that, are inclined to have particularly fascinating chook communities. You by no means know what you would possibly discover. Earlier occasions have turned up rarities similar to Kirtland’s and golden-winged warblers, and American goshawk. However largely, collaborating within the Atlas-3 is about looking for, discovering and having fun with our great birds in neat locations with nice folks.
I hope you’ll be part of us.
