Sudden flashes of green and orange brighten the dusty landscape of this desert.
Sitting for a short while on branches or power lines these insect-eaters look for breakfast, lunch and dinner.
The memory of the flash of emerald green that catches your attention as it perches is washed away as it spots its prey and swoops with the bright orange beneath its wings providing the colour.
Then, happy with the first part of its meal, it waits hopefully for another flying insect to catch its eye.
Sometimes you can catch them showing orange even when they are perched. When the sun is right and the wind ruffles their feathers. This last is a male because the streamers from its tail are longer and finer than those in the first three images.
