The White-bellied Sunbird Cinnyris talatala is a common which is found in Acacia and other woodlands in the Western Free State, Gauteng, Limpopo, Mpumalanga and Natal provinces of South Africa (Hockey et al. 2005).

It usually nests in plants which have thorns (Hockey et al.

it may occasionally hang its nests on artificial structures washing lines (Tarboton 2011).

On 8 July 2013 I visited the farm Boscia which is located

Brits (S25°32.117' E27°44.742'). Orchids are grown on the farm in a greenhouse. Nollie Cilliers, one of the farmers, showed me two White-bellied Sunbird nests in the greenhouse. The nests were attached to a wire that is part of the side construction of the greenhouse. Both nests were only a few centimetres from the sidewall of the greenhouse which is made of a plastic material

The one nest was located in the front of the greenhouse only a few meters from the main entrance. In this instance it is quite easy for the adult and immature birds to enter and leave the greenhouse.

However, the other nest is at the back of the greenhouse and the
