This rather distant, back-illuminated view of an Eastern Grass Owl provides the "jizz" of the bird: blunt head, powerful wings, short tail and long, dangling legs extending well beyond the tip of the tail

Behaviour

(Eastern) Grass Owls have particularly long legs, an adaptation enabling them to walk on the ground in tall grass. Astonishingly, they roost and breed on the ground too. When disturbed, they will fly only a short distance before dipping down into dense growth again.

Here an impression of what was left at the end of harvest for an Eastern Grass Owl to hide in - yet one cannot see the bird that has just landed there at all

After the end of harvest of the winter crop, this was the only remaining suitable habitat left for Eastern Grass Owls: a mixture of grass, reed and weed growth in shallow, usually dry, creek beds or gullies
