Little owl Behavior and Adaptation

The Little owl is primarily a territorial species, with males remaining in a single habitat for his whole life, depending on the availability of food sources. Their boundary often expands, especially in the mating season.

This owl species is diurnal. They can often be seen sitting in a tree branch during daytime looking around for potential prey. At times, they go after their prey on the ground. They save surplus foods in their nest.

As the breeding season comes close, males become more vocal after sunset. Their nesting location depends on their habitat. The male emits territorial calls if it sees an intruder in its territory. If the intruder does not leave, the occupier goes after him aggressively. Male defends its territory against unknown males rather known males from a nearby territory.

In urban or suburban areas, they get used to human presence, and they remain seated on a tree branch even if they see humans around.

Little owl Reproduction

The breeding period starts with the male patrolling his territory and making calls that serve as a warning to other males and also mating call to attract a mate. Depending on region and habitat, their breeding season starts in early February or late May. Pair bonding is formed with both owls sitting together on a perch, and flying together. During this time, the male feeds the female so that she can gain weight that in turn helps her in egg formation and incubation process.

Reproduction of Little owl

Reproduction of Little owl

As their bonding strengthens, their vocalization increases. Both male and female take part in selecting a nesting site. Females lay a clutch of 1 to 7 eggs (however, 12 eggs clutch have been recorded). If the first clutch gets lost for some reason, they often produce a second clutch with a small number of eggs. Incubation starts as soon as the eggs are laid. The incubation period lasts for 28 days on average. After hatching, the owlets stays dependent on its parents for two months. The hatchlings weigh 10 to 13 grams. In the first two to three weeks, the little ones are taken care of by the female. After a month or so, the offsprings start to fly and are able to catch prey on their own. Within 4 to 6 months, the juveniles leave the nesting site. They reach sexual maturity at the age of one.

Little owl Diet

This owl species is quite an opportunistic carnivore feeding on a great variety of prey including other birds, mammals, fish, reptiles, insects, amphibians and invertebrates.

Little owl Life expectancy

The median lifespan of the Little owl is 4 years. However, the longest known lifespan of this species is 15 years and 7 months in the wild. The mortality rate of adult specimens tends to be somewhere between 24.2% to 39% each year. In the case of juveniles, this number is a lot higher, ranging between 69% to 94%.

Little owl Vocalization

Their primary call is an irritable ‘kiew’ sound. They also utter different chattering, trilling, and whistling calls within the domain of the nest. During breeding season, more attune calls are made. The male produces a mellow ‘gooekk’; while both sexes emit a loud ‘hooo; sound.

Little owl Threats

It is believed that the world population of this bird is somewhere between five to fifteen million, with Europe covering 25 to 49 percent of the total range. Even though they are found in sufficient numbers in their native habitat, yet the loss of habitat, industrialised farming practices are considered as a great threat.
