Another suggested adaptation to help yellow chats survive in the arid region is their brush tongue. The brush tongue may be an adaptation to aid in retrieving drinking water. It allows the birds access to dew and the capability to drink thin water films, such as water seepages on surfaces of plants. Furthermore, the colour of their plumage is an adaptation aiding in their thermoregulation. Black pigments have been observed to increase heat absorption, with lighter colours absorbing less heat. This suggests that the yellow colouring of the yellow chats is an adaptation to reduce the amount of heat absorbed in their body.
