Eastern Barn Owl (Tyto javanica) lives in forest across Southeastern Asia. It feeds on small mammals rodents. Its conservation status is Least Concern.
Fascinating facts about the Eastern Barn Owl
- The eastern barn owl normally hunts under cover of darkness, but on a few Pacific islands it abandons this habit and pursues prey in full daylight. This daytime activity has been observed on various islands and may be linked to whether the owl is mobbed by other birds when it appears in the sun. By shifting its hunting schedule it can still exploit the same ground-dwelling mammals it relies on for food, using its acute hearing to locate them.
- Eastern barn owls have been recorded on remote islands such as Norfolk Island, Lord Howe Island and New Zealand, demonstrating that they can cross open ocean to reach new habitats. Their first confirmed breeding in New Zealand occurred in 2008, confirming that they not only arrive but also establish nesting colonies.
- When swarms of tiny mammals become abundant, eastern barn owl numbers can increase dramatically because the birds can expand their populations rapidly. An individual may consume one or more voles or equivalent prey each night, amounting to about twenty-three percent of its own body weight, a high intake that supports fast breeding.
- A single eastern barn owl may eat one or more voles or equivalent prey each night, which equals about twenty-three percent of its own body weight. This intake is driven by a metabolic demand that is unusually high for an owl of its size, meaning it must capture more food than many relatives. Compared with other similarly sized owls it has a much higher metabolic rate, requiring relatively more food.
- While incubating, the female does not bring in twigs or leaves; instead she pulls in the dry, furry remains of her regurgitated pellets to line the cavity. This creates a soft carpet of shredded material that cushions the eggs and later the hatchlings. By the time the chicks emerge they are surrounded by this pellet-filled bedding, providing insulation and a familiar scent. The use of pellet material as nesting lining is a distinctive behaviour of the species.
