Atlas I
1980 – 1985
Ed. Andrle & Carroll, 1988
The first statewide inventory of New York's breeding birds. Paper field cards, 5,332 blocks, and the definition of a baseline we are still measuring against.
Three statewide atlases. Two and a half decades apart. A quarter‑million five‑kilometer surveys, pressed between the pages of one living record of New York's birdlife.
Since 1980, volunteers across the state have walked the same five-kilometer survey blocks, listened for the same dawn songs, and added up the same cryptic breeding codes. Taken together, the three atlases tell a story you cannot see in a single summer: a quiet rearrangement of where our birds live, and why.

A full generation later, the state was quietly different: peregrines nesting in cities, bluebirds rebounding, grassland sparrows slipping south. 1,200 volunteers, half a million records.
The first digital atlas, built on eBird. Field data flowed in at dawn from phones on hilltops and porches. More than 4,000 contributors submitted more records than any prior atlas. Results are being written now.
The atlas blocks are the rows of a very slow spreadsheet. Each one is a five-kilometer square, walked by a rotating cast of volunteers, repopulated every twenty years. Hold three side by side and the decades begin to move.
Every species account stitches together three atlas periods, modeled occupancy, breeding phenology, and the plain prose of change. Here are five that moved more than the rest.
An atlas is not a census. It is a shared grammar of evidence. A singing male is possible breeding. A male on territory is probable. A nest with eggs is confirmed. Walk a block enough times and the birds tell you which one.
Toggle any species over any decade. Pin a county and pull its full checklist. Draw a polygon around a wetland, a ridge, a back road, and export the raw records behind every mark.
The 2048 atlas starts with the birds you see tomorrow morning. Submit to eBird, join a local chapter, sign up for a block. Every record lands here.
