Trends 2014-2022

Breeding Season, 3. mai - 30. aug

This map depicts the cumulative change in estimated relative abundance from 2014 through 2022 with circles representing 27km x 27km regions. Red indicates decline and blue indicates increase. The darker the color, the stronger the trend. White circles represent locations where the trend estimate is not significantly different from zero (i.e., the 80% confidence interval contains zero). Circle sizes are scaled by the estimated relative abundance at the middle of the time period.
