Charles Clarkson uses the rate of feather growth in nestling waterbirds, such as this glossy ibis, as a biomarker of methylmercury (MeHg) contamination of local estuarine habitats. High doses of MeHg in the diet of developing chicks can prolong the nestling phase and increase the amount of time a chick is vulnerable to predation. Photo by Charles Clarkson.
