Photography as an efficient tool to study moult

Bird feathers fulfill several roles but must be in good condition to efficiently function. To maintain the feathers in a good state of repair birds regularly replace their old feathers with new ones during moult. This is a costly process and of interest to avian ecologists. To study moult, ornithologists needed to catch birds, but this may no longer necessary.
