Karoo Thrush

The Karoo thrush (Turdus smithi), also recognized as Smith's thrush, is a medium-sized bird, measuring approximately 24 cm in length. It boasts a wing span ranging from 117 to 131 mm, a culmen (the upper ridge of its bill) from 20 to 24 mm, and a tarsus (the part of the leg between the knee and the foot) from 30.0 to 34.5 mm. This avian species can weigh upwards of 86 grams. It is distinguishable from its relative, the olive thrush, by its entirely yellow bill, longer wings, and notably greyer flanks.

Identification Tips

When observing the Karoo thrush, look for its longer, completely yellow bill, which sets it apart from the olive thrush. Its wings are elongated, and the flanks exhibit a grey hue, contrasting with the yellow flanks of the olive thrush.

Habitat

The Karoo thrush is a resident of South Africa, thriving in regions such as Little Namaqualand, the Karoo, and Northern Cape, as well as the Free State, Gauteng, Limpopo, Mpumalanga, and parts of the North West Province.

Distribution

This species is endemic to South Africa, with its presence confirmed in the aforementioned habitats across the country.

Similar Species

The olive thrush is a similar species to the Karoo thrush, with potential for hybridization. However, the Karoo thrush can be differentiated by its yellow bill, longer wings, and grey flanks.

Conservation status

The IUCN Red List has classified the Karoo thrush as Least Concern, suggesting that, currently, there are no immediate threats to its population levels that would warrant a higher risk category.
