Trends 2012-2022

עונת הקינון, 26 אפר׳ - 16 אוג׳

This map depicts the cumulative change in estimated relative abundance from 2012 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.
