|Budgerigar - Melopsittacus undulatus|
The Budgerigar - Melopsittacus undulatus - is a small, slender-bodied, bright green parrot. Yellow throat and forehead; blue, black throat spots. Pale wing bar in flight. Size 18 centimetres. Escaped domestic budgerigars may be yellow, blue, lilac, white, grey and different greens.
Lives on arid and semi-arid plains and ranges in spinifex, saltbush and grassland; treeless or with scattered trees and shrubs. Avoids heavy forested regions. Lines of trees along watercourses and stands of open eucalyptus woodland scattered through open country provide nesting hollows with water available from nearby pools. Budgerigars can survive for some time without water but are rarely found far from it; but fast-flying flocks can cover considerable distance to water sources.
Usually in small groups but also in densely-packed, fast-wheeling flocks catch the sun and changing massed colour as they turn.
Abundant and highly nomadic. Responds to heavy rain by congregating where lush grass ensures abundant seed and quickly raises several broods, each up to eight young. The resultant population increase forces the birds to disperse as soon as arid conditions return.
