The mighty big 6 birds of the Kruger - The Pel's Fishing Owl

The Pel’s fishing owl was named after the Dutch governor, Hendrik Severinus Pel, of the gold coast between the years of 1840 and 1850. A shy and elusive owl, it would be a magical and unforgettable experience to spot one.

With an average wingspan of 153cm, a length of 51 to 61cm and an average weight of 2188 grams makes the Pel’s fishing owl one of the largest owl species on the planet. They are said to be the fifth heaviest owl in the world.

These are ginger coloured owls with a round head and haunting like black eyes. Their underparts have dark bars and their underside is a paler colour. Females are usually a paler ginger colour than their male counterparts while owlets have a whiter coloured body and head, only growing their adult plumage by the age of 15 months old.

They do not have the characteristic facial discs, like most owls, because hearing is not important when locating their underwater prey. Their feathers are not as soft and lights as other owls as they do not need to be silent for hunting underwater prey.

Habitat

These owls live in sub-Saharan Africa, found in countries such as Senegal, Somalia, Namibia
and the north eastern parts of South Africa. They are the most widely distributed of all fishing owls.

Pel’s fishing owls make their homes in large trees along the banks of rivers and on the edges of lakes, swamps and in wetlands. They do not participate in seasonal movement like some birds.

Behaviour

Owls are nocturnal animals, who are more active and vocal during the night under the cover of the darkness. Pel’s fishing owls are most active on moonlit nights however they are sometimes active during the day. The male and female pair will usually roost together during the day and at dusk leave to perch on branches near or over the water.

Vocals

They are mostly vocal during the night and are most vocal an hour before dawn breaks. Their calls have been described as bone chilling and haunting and have been compared to someone calling from the bottom of a well.

Their hoots are used as communication calls and during the breeding season they perform duets with their partners. Males have a deep and rumbling call which are repeated six to seven times within a minute. Females have a higher pitched call that is usually only a single hoot and then followed by a double hoot. Their calls can be heard up to 3 kilometres away.

Diet

Pel’s fishing owls eat mostly fish but will indulge in eating frogs, crabs, mussels, insects and even small baby crocodiles.

They detect their prey using sight by watching for ripples made by fish as they near the surface of water. Their toes are covered in spiky scales to help hook and catch their fishy meals. Unlike most owls, Pel’s fishing owls lack feathers on their legs and toes, to minimise the amount of plumage to get wet while hunting.

Reproduction

These owls pair up in monogamous couples and claim a territory near water by using stern hooting.

The pair breeds during the dry season when the water is shallow and clear. They set up home using a natural hollow in an old tree and do not add any extra nesting material. The female incubates the laid eggs (weighing 85g each) for up to 32 days while the male provides the food. Sadly usually only one of the two eggs survives.

The chick that survives fledges the nest at 68 to 70 days old and will continue to live in their parent’s territory until they are 6 to 9 months old. Chicks grow their true feathers by the time they are 10 months of age.

Did you know?

The Pel’s fishing owl will fluff up their head feathers when distressed making its head appear larger.
