This video from the USA says about itself:
A Wood Thrush returns to its nest with food for its mate and young
27 January 2016
Wood Thrush breed in deciduous and mixed forests in the eastern U.S. where there are large trees, moderate understory, shade, and abundant leaf litter for foraging. Here, a pair of Wood Thrush tends a nest. One of the adults returns with food for its mate and small young. The parents remove fecal sacs, produced by the nestlings, to keep the nest tidy.
