Cattle egret (Bubulcus ibis)

Kuntul kerbau or buffalo egret or cattle egret (Bubulcus ibis) is the smallest bird of the herons to about 50 cm long, likes to look for food in rice fields that are being hijacked or planted. This bird is leaner than Blekok sawah or Javan pond heron (Ardeola speciosa), although not as large as larger egrets.

B. ibis has white throughout the body, but during the mating season it has a yellow color on the head, neck, back and chest. This bird has a shorter neck, a rounder and thicker head, a beak about 9 cm or shorter than other herons. The beak is yellow and the legs are black.

When breeding it is good to live in a large tree with other herons. Their togetherness makes predators reluctant to approach. Birds nest in large colonies and like to live around rice fields, swamps, mangroves, swamps and grasslands to eat insects, frogs, eels, crabs, shrimp, snails, rats and snakes.

B. ibis likes to join with cows and buffaloes where in the afternoon small groups do fly low in a row towards the nest to rest in the big trees. These cosmopolitan animals often follow the activities of farmers who are plowing or processing land in the fields.



The cattle egrets remain residents of a tropical climate, but they also live in cold regions to immigrate to warmer areas after the breeding cycle. The long and extraordinary migration journey continues and often appears on remote islands in the Pacific.

One of the key factors for this bird expansion is adaptability. Although most egrets prey on aquatic animals, Kuntul kerbau prefer insects and have strong stamina. They crossed the Sahara to traverse 4000 km of West Africa and South America.

God is tools

OPINION - God and spirit are controversial discussions in science and even mythology will have no place among naturalists and for Darwinians. Apparently this has been final that mythology is a delusional, mystical and superstitious concept that cannot be empirically proven in the world of science.

Most scientists and science activists have agreed that god is nonsense, delusional and cannot be accommodated in the theory of evolution. This opinion can be understood methodologically and I agree with the sentences. But so many behaviors are very real and occur in the field.


I am a fieldman who goes to the wild every day, along rice fields and forests to watch insects to plants, talk to people especially in villages, visit Hindu-Buddhist temples built in the 8th century, witnessing busyness in mosques, temples and churches.

I feel something is missing in the view of naturalists and Darwinians. There are short moments that are missed in analyzes in the timeline of human evolution. These lit…
