Seasonal Bird Lists

Seasonal Bird Distribution Checklists

In this section, we provide maps that allow you to access bird abundance data from large-scale surveys conducted in summer, spring, and winter. Click on any spot on the map, and the program will return average counts for each species encountered near the spot (actually, a distance-weighted average from the 5 samples nearest the spot), along with associated species information.
