Atlasing is easy, and something that you’ve probably already been doing without knowing it! This page has everything you need to atlas with confidence.
The only difference between ‘atlasing’ and observing bird behavior is making sure that your checklists follow block boundaries. To be a part of the New York Breeding Bird Atlas, you only need to follow the three easy steps below. The pages linked below have comprehensive explanations if you have further questions.
The entire state is split up into roughly 3 mile x 3 mile squares. These are BBA blocks, and all of your atlas lists need to include birds from only a single block.
If you watch birds, you already notice bird behavior. With the atlas, you match what you encounter to specific codes (e.g., a singing bird = S; a bird building a nest = NB). Use these codes whenever you see a behavior.
To have your sightings count for the atlas, you need to use this specific portal. You should use the portal for all checklists in NY from now through 2024 when you are following block boundaries and actively keeping an eye out for bird breeding behavior (and noting codes for behaviors you find).
