Habitat

It prefers riverine bush and montane forest. It has adapted to alien tree plantations, gardens, parks and fruit orchards. In particular, Olives Thrushes like well-shaded places with damp soil and moist leaf litter. They also love a bird bath!

Behaviour

The Olive Thrush is a rather shy and unobtrusive bird. It can often be found in the quieter corners of a garden, under trees and bushes, while it is looking for food.

It mainly eats earthworms supplemented with insects. It also eats other invertebrates and fallen fruit. The Olive Thrush does most of its foraging on the ground, flicking through leaf litter in search of prey.

The female builds a cup nest, typically up to 6 m above the ground in a tree. The Olive Thrush especially likes to nest in gardens, so keep an eye out! The 2-3 eggs are incubated mainly by the female for 14-15 days to hatching, and the chicks fledge after about another 16 days. The young ones remain dependent on their parents for up to 2 months after fledging!

The Bird Feeder Project is a BDI citizen science initiative involving school learners and youth eco-clubs. Learners are taught a scientific protocol for doing 10-minute watches and recording the species they see, in the order they see them. The Bird Feeder Project includes an online identification guide to about 30 of the species seen in gardens in Cape Town. Students will learn how to upload their cellphone photos into the BirdPix section of the Virtual Museum, where they will be curated for posterity. The 10-minute watches will rapidly grow into a valuable monitoring database. Karis Daniel is the Project Coordinator and put together the identification guide, Megan Loftie-Eaton helped with the species texts.
