Rockin Robin

Female robins build their nests mostly out of twigs and grass, but also collect feathers, roots, moss and even paper to add on. To line their nests, they procure fine grass, and press it down within the cup to cushion the eggs. On the bank of Gull Lake I watched a female gathering grasses to construct the fundamental structure of her nest. She then flew up to a nearby oak and began working with the materials, losing a few on the way up, but retain the bulk of it.

Standing upon a rock with a beak full of dead grasses, this robin is carefully selecting her building materials.

This may be one of up to three nests that a female may produce in one season, although not all her nests will be active; only some 40% will be filled with little light blue eggs.
