Despite dramatic population recovery, bald eagles continue to succumb to lead (Pb) toxicosis in substantial numbers that may be artificially suppressing populations. By conducting a meta-analysis using multiple data sources from the Northeast, we will have increased statistical power to identify if Pb impacts population growth. Our meta-analysis will be capable of identifying common patterns or other disagreements between results and their potential sources of bias. This information will be useful for state, provincial, and federal agencies to craft communication messages around Pb issues.
