Birds of prey are birds that hunt for food primarily on the wing, using their keen senses, especially vision. Their talons and beaks tend to be relatively large, powerful and adapted for tearing and/or piercing flesh. In most cases, the females are considerably larger than the males.
birds of prey are formally classified into five families:
The list below is what I use for the guidelines for this group if your image was deleted from the group then it does not fall into any of these categories.

1. Accipitridae hawks, eagles, buzzards, harriers, kites and Old World vultures
2. Pandionidae the Osprey (sometimes classified as subfamily Pandioninae of the previous family)
3. Sagittariidae the Secretary Bird
4. Falconidae falcons and caracaras Polyborinae
5. Cathartidae New world vultures including condors.

The nocturnal birds of prey – the owls – are classified separately as members of two extant families of the order Strigiformes:

1. Strigidae typical owls
2. Tytonidae barn and bay owls
