Breeding / Reproduction Behaviour

While more research is needed to be able to determine what the breeding season of the Black-Chested Buzzard Eagle is, it is known that the male and females form partnerships that typically will last for an entire lifetime.

During the first breeding season, a male and female Black-chested Buzzard Eagle will court each other by flying together, and will then proceed to mate with each other for a period of around 7 weeks.

After this period of time, the female will then lay a clutch that typically consists of 1 to 3 eggs, and she will then take the majority of responsibility for incubating the egg(s).

Once hatched, the offspring will usually be covered in white down, and the parents will work together to raise their chick(s) until fledging occurs.

If needed, the Black-chested Buzzard Eagle will also hunt a variety of other types of food, including insects.

As for the way that they hunt, the Black-chested Buzzard Eagle is an incredibly agile hunter, and will usually take to the skies, using their powerful wings to circle areas where prey might be residing.

The Black-Chested Buzzard Eagle will typically nest in extremely high trees for safety while ensuring that their nest is positioned under the canopy of treetop leaves for protection from any overhead threats.

However, if they are not in an environment where trees are readily available to nest in, these cunning birds have also been known to nest in rocky cliff areas (including steep cliff edges) as well as ground foliage if they have seemingly no other option.

The nest itself is usually very large (85cm/33inches) and is often made by both the male and female counterparts, who work together to collect sticks and leaves from surrounding areas.

How Long To They Live (Lifespan)

On average, a Black-chested Buzzard Eagle will live for an average lifespan of 14-20 years.

However, it should be noted that a variety of factors can potentially affect the length of how long a Black-Chested Buzzard Eagle will live, including biological as well as situational factors, too.

What Predators Do They Have?

Due to the large size of the Black-Chested Buzzard Eagle, it means that they do not tend to have many predators to be wary of while in the wild.

Nevertheless, the Black-Chested Buzzard Eagle will be at risk of being hunted by eagles that are larger than it, as well as being illegally hunted by humans, too.

What Are Their Feathers Like?

Once matured, Black-chested Buzzard Eagles typically look greyish blue in appearance and usually have white and black markings intersperse all throughout their feathers.

Usually, they will have greyish-toned shoulders with black/brown bars running down the body, as well as a darker breast area.

The underparts and belly of the adult Black-chested Buzzard Eagle tends to be white with subtle bars, and the tail is often black with grey bars running in a vertical direction.

As for the juveniles, once born they are initially covered in white down with brown patches, although this usually develops into dark brown or black all over, with a barred breast area.

Typically, it takes juveniles around 5 years before they take on the distinct feather markings of the adults.

In addition to this, it is also worth noting that, while male Black-chested Buzzard Eagles tend to have a blueish-grey tone to their feathers, the females will usually have a reddish-brown colouring across their back area running down to the tail, which helps them to be differentiated from the males.

What Does Their Poop Look Like?

As we’re sure that you’ll likely already be able to guess, the Black-Chested Buzzard Eagles poop typically tends to consist of a runny texture when fresh.

In addition to this, due to the fact that Black-chested Buzzard Eagles are unable to urinate, it means that their healthy poop is covered in white excrement.
