across North America with 79% of 54 total sites showing stable counts during this span. There have

sites have reported an increase. Regional populations appear
mostly stable with 19% of sites showing decreasing counts in
the East Region. The Gulf Region has observed 33%
increasing trends (see pie charts and trend maps below). 20-
year count trends (not shown) also reflect a mostly stable
