Over the 15 years of the study, these changes produced substantial differences in risk factor levels.

Until recently the cause of death was assumed to be, inter alia, gases of volcanic origin which may have collected over the lake. This might explain why the animals suffocated.

A key indicator of the songbirds' health and quality is the concentration of carotenoid in the feathers, which causes orange-red light to be reflected in their feathers.
