This survey consisted of 233 plots, each 168.3 km2. The expanded population es...
However, scientists estimated that bald eagle growth rates were suppressed by 4.2% for females, and 6.3% for males. "Even though the population seems like it's recovered, some perturbation could come along that could cause eagles to decline again," Schuler said....
