Nest structure: The song thrush

1

A female song thrush selects a site, often a triple branch fork, on which she constructs a base platform of twigs. This is then filled with moss.

2

She constructs a cup from grass stems, tucking and then twisting them into each other. Finer grasses are woven into the rim for strength.

She adds moss and a few leaves to the outer cup for camouflage, before lining the nest with wood pulp and mud, using her body to smooth it down.
