When visiting South America, I frequently saw a American Robin-like bird called the Austral Thrush.
The yellow bill and behaviour are very similar.
All that is missing is the orange breast of the American Robin.
Austral Thrushes are found in town parks, gardens, woodlands, forests, and other semi-open habitats, usually in areas with taller trees nearby.
They feed mainly on the ground, often on lawns, and also in fruiting bushes and trees. In Santiago Chile, every small park seems to have one.
They seem to have very large feet.
The diet consists of worms, snails, and arthropods (including insect larvae and pupae) and much fruit.
