Appearance

This bird is grey in appearance with a much longer body than some of the other harriers that you might find out in nature. It has a downy brown-grey set of feathers on the back with a much darker brown along the tail.

The adult pied harrier has a white breast which helps you to identify it in the wild. The young chicks tend to have lighter feathering, although this will get darker as they get older. This bird also has forward-facing eyes and has a similar look to an owl.

The reason why it has evolved forward-facing vision is to help it with hunting.

This bird is not as big as some of the other birds of prey, although they still have a very large wingspan in proportion to their body. This bird likes hunting very small mammals such as rabbits, squirrels and other smaller birds of prey.

Male Vs Female

The female of this species is typically larger than the male, with a much lighter grey feathering and a low color on the breast. They also come with a whiter coloring on the rump.

Female pied harriers also resemble Pallid and Montague harriers, although they have paler underwing and dark barring on the back.

The male has a much darker head than the female, with black shoulders and wingtips. This beast has vivid yellow eyes and cere, which will make it easy to spot when out in the wild. The males and females have a silvery belly, breast and forewing.

Are They Aggressive?

These birds are not really that aggressive to humans, although there have been reports of the occasional attack, this is largely due to the fact that humans are getting too close to the bird’s nest.

The only time you will see a pied harrier behavings aggressively is when they are hunting their prey. 

What Adaptations Do They Have?

These animals have plenty of adaptations, which makes them one of the most deadly predators that you can find in the wild. They have retractable claws that they use to carry their prey across long distances.

They also use a hooked beak that helps them to sever the bones of their prey from the flesh.

This animal also has developed a larger wingspan that helps it to hover on the breeze. The reason for this is that they can scan the forest floor to look for prey.

Having this ability to stay completely still in the air will also not give its position away to predators.

Breeding/reproduction Behaviour

The breeding season for these birds usually lasts for around half a year, starting in around June and ending towards the end of the fall.

These seasons will usually be dependent on how warm the climate is. The warmer that it is then the longer the birds will want to reproduce.

These birds will usually mate for life, with the male usually sticking around to help feed the chicks and make repairs to the nest. This bird will usually lay around 2 – 6 eggs, although some of these chicks might not survive past infancy. This is a process called siblicide.

Siblicide is when the stronger sibling will die during the early days of hatching, however, this process is actually helpful for the young chicks surviving past infancy.

This way they will grow much stronger, taking a lot of the food that would have gone to their bigger brothers and sisters.

Their Calls/Sounds

These birds will often use bird calls to establish their territory. You’ll often find that these birds emitting a sort of high-pitched yipping sound. The female will often issue an attraction call to a potential mate when they are ready to breed.

The chicks will often let out an even higher-pitched call to arouse the attention of their parents, usually for food.

Conservation Status

This creature is low on the endangered species list, with a conservation status of ‘least concern’. The one major factor that has affected the population of these animals is the encroachment of human beings onto their territory.

Decimation of forest habitat to make way for housing is also another reason why this animal has dwindled in numbers since the 70s.

There are currently thought to be around 10,000 pied harriers currently available in the wild. This makes them a moderately endangered species.

Fun Facts

The word ‘harrier’ is derived from a Greek word that means ‘to circle’, which is derived from the bird’s flight pattern.

A mlae will often display its plumage in flight to attract a female, sometimes using its unique cry to get their attention.

If one bird in a pairing dies, the widow will often go and find a mate very quickly for the next breeding season.
