Ghostly pale and normally strictly nocturnal, Barn Owls are silent predators of the night world. Barn owls tend to live longer in captivity and have a lifespan of about 20 years. Barn owls have a typical wingspan of some 80 to 95 cm (31 to 37 in), with a full range of 68 to 105 cm (27 to 41 in). [87], In Malaysia, large areas of rainforest were felled to make way for oil palm plantations and with few tree cavities for breeding, the barn owl population, with its ability to control rodent pests, diminished. North America from southern Canada south to central Mexico; Small. How­ever, the longest recorded lifes­pan of a wild barn owl … The male continues to copulate with the female when he brings food which makes the newly hatched chicks vulnerable to injury. It occurs most often amongst inexperienced young birds during juvenile dispersal or in periods of severe winter weather. [24] In general, it is considered to be sedentary, and indeed many individuals, having taken up residence in a particular location, remain there even when better foraging areas nearby become vacant. Weight for weight, barn owls consume more rodents—often regarded as pests by humans—than possibly any other creature. Collisions with power-lines kill some birds and shooting accounts for others, especially in Mediterranean regions. For example, a bird lying dead on a road is much more likely to be reported than a bird that’s died in the middle of a field. [84] In May 2012, it was revealed that farmers in Israel and Jordan had, over a period of ten years, replaced pesticides with barn owls in a joint conservation venture called "Project Barn Owl". [45], Feathers become abraded over time and all birds need to replace them at intervals. On bird-rich islands, a barn owl might include some fifteen to twenty percent of birds in its diet, while in grassland it will gorge itself on swarming termites, or on Orthoptera such as Copiphorinae katydids, Jerusalem crickets (Stenopelmatidae) or true crickets (Gryllidae). In some locations, road mortality rates can be particularly high, with collision rates being influenced by higher commercial average annual daily traffic, roadside verges that are grass rather than shrubs, and where small mammal abundance is high. Based on over 8,000 BTO ring recoveries, it has been calculated that the average life expectancy of all British Barn Owls above 5 weeks old is just less than 18 months. [74] [75], The provision of nest boxes under the eaves of buildings and in other locations can be very successful in increasing the local population. [70], Common names such as "demon owl", "death owl", "ghost owl" or "lich owl" (from lich, an old term for a corpse) show that traditionally, rural populations in many places considered barn owls to be birds of evil omen. The male is the main provider of food until all the chicks are at least four weeks old at which time the female begins to leave the nest and starts to roost elsewhere. Although this is the case, the barn owl population is more predominant in the Southern Hemisphere due to better climate conditions for the barn owl. The oldest wild barn owl lived 34 years. [39][40], The barn owl hunts by flying slowly, quartering the ground and hovering over spots that may conceal prey. [9] However, the International Ornithological Committee has doubts about this and states that the split of Tyto delicatula from T. alba "may need to be revisited". Its underparts are white, cream or buff with fine, dark-brown streaks. [30] This owl prefers to hunt along the edges of woods or in rough grass strips adjoining pasture. The incubation period is about thirty days, hatching takes place over a prolonged period and the youngest chick may be several weeks younger than its oldest sibling. In spite of a Recovery Strategy particularly in 2007–2010 in Ontario,[63] only a handful of wild, breeding barn owls existed in the province in 2018. [1][60] However, locally severe declines from organochlorine (e.g., DDT) poisoning in the mid 20th century and rodenticides in the late 20th century have affected some populations, particularly in Europe and North America. For males in Scotland this has a radius of about 1 km (0.6 mi) from the nest site and an average size of about 300 hectares. [67][68][69] The size of the owl varies depending on the subspecies, as some are types are larger than others. Underparts whitish to light buff with much speckling. As the breeding season approaches, the birds move back to the vicinity of the chosen nest to roost. 2. [43], Barn owls living in tropical regions can breed at any time of year, but some seasonality in nesting is still evident. [73] In South Africa, Barn Owls are often persecuted and associated with witchcraft. The secondary and tail feathers are lost and replaced over a similar timescale, again starting while incubation is taking place. Often there are simple, practical solutions to these problems. In northern and upland areas, there is some correlation between mortality in older birds and adverse weather, deep-lying snow and prolonged low temperatures. Reddish-brown below. Both young and old animals produce a snake-like hiss defense when disturbed. Most barn owls do not live very long. For example, the Tzeltal people in Mexico regard them as "disease givers". Face white. Upperparts grey and orange-buff. Nest boxes are popular among conservationists who motivate farmers and landowners to install them for use as natural rodent control. In the British Isles, the young seem largely to disperse along river corridors and the distance travelled from their natal site averages about 9 km (5.6 mi). After they leave their parents' territory, life for a Barn Owl becomes very difficult. About 12 other large diurnal raptors and owls have also been reported as predators of barn owls, ranging from the similar-sized Cooper's hawk and scarcely larger tawny owl to huge bald and golden eagles. 1987. Bats and even frogs, lizards and snakes may make a minor but significant contribution to the diet; small eulipotyphlans like Suncus shrews may be a secondary prey of major importance. By three weeks old, quills are starting to push through the skin and the chicks stand, making snoring noises with wings raised and tail stumps waggling, begging for food items which are now given whole. The plumage on head and back is a mottled shade of grey or brown, the underparts vary from white to brown and are sometimes speckled with dark markings. Barn owl pairs typically stay together as long as both members of the pair are alive. They do not create a nest; rather they deposit the eggs in manmade structures such as towers, barns, etc. Although the bulk of its diet is composed of small mammals, the Barn Owl will also catch other birds, amphibians, and large insects. The female starts to moult while incubating the eggs and brooding the chicks, a time when the male feeds her so she does not need to fly much. [48], Predators of the barn owl include large American opossums (Didelphis), the common raccoon, and similar carnivorous mammals, as well as eagles, larger hawks and other owls. With its distinctive heart-shaped face, pure white feathers, and ghostly silent flight, it's easy to identify. Compared to other owls of similar size, the barn owl has a much higher metabolic rate, requiring relatively more food. [47], In temperate areas, the male owl moults rather later in the year than the female, at a time when there is an abundance of food, the female has recommenced hunting and the demands of the chicks are lessening. In the wild, many young barn owls do not survive their first year of life. Underparts white, with few if any black spots; males often appear entirely unspotted. This in turn is determined by habitat quality, prey abundance, the weather, and the abilities and behaviour of the individual parents. Did you know? Life expectancy has many contributing factors like habitat and can vary depending on whether it is in captivity or in the wild.
