This map depicts the ranked amount of change during the breeding season in estimated relative abundance across the years 2007-2016. Circles are colored by ranked increasing or decreasing trends and circle sizes are scaled by the maximum estimated relative abundance across 2007-2016. Light gray circles represent locations with trends not significantly different from zero.
eBird data from 2004-2016. Estimated for 2007-2016.
