Egret sp Flock Flying over the Forest

For the last two weeks, I have seen the flock of Egret flying over Raub.
Usually four to ten birds in the flock. So far it not yet landed at my backyard.

Four Egret species flying over the forest.

This landing Little Egret was photographed in March this year.

Little Egret is resident migrant in Malaysia. Migrant population add the number of this bird, so that why I can it at my backyard now.
