Rock wren nest

Rock wren nest

Rock wrens dart about rapidly, flying close to the ground in bursts of a few metres. When standing they bob up and down. They live in the mountains above the treeline, staying close to their nest all year, and surviving winter snows by sheltering in rock cavities. This wren is bringing feathers to line its nest, which is concealed in a pile of scree. Hundreds of feathers are used to insulate the chicks, which hatch in late winter. The parents change the nest lining frequently to keep it clean and dry.
