Tricky birds of central Victoria - raptors

It’s a hawk!

What is a raptor?

• Birds of prey, also known as raptors, are birds that hunt or feed on other animals

• The term "raptor" is derived from the Latin word rapere (meaning to seize or take by force)

• Raptors have keen vision that allows them to detect prey during flight and powerful talons and beaks. In most cases, the females are larger than the males.

In ornithology, the term raptor, refers to the following families:

Diurnal birds of prey

• Accipitridae: hawks, eagles, buzzards, harriers, kites and Old World vultures

• Pandionidae: the osprey• Sagittariidae: the secretary bird• Falconidae: falcons and caracaras

Nocturnal birds of prey

• Strigidae: typical owls• Tytonidae: barn owls

Because of their predatory nature they face distinct conservation concerns.

Identifying raptors … my top three tips

1. Acquire a ‘top notch’ field guide

2. Spend time in the field

3. Learn the ‘spotting characteristics’ for your target species

These are not raptors … nor are they owls!
