Identifying birds in flight has its own set of challenges. These include:
- Bird may be seen for a short period of time
- Colors not obvious
- Shape can change depending on situation. For example, the tail feathers may or may not be spread.
Hawks, eagles and vultures are often observed soaring, and certain characteristics can help narrow down your choices. In soaring birds, shape and relative areas of light and dark are good clues. With experience, the way a bird flies will often reveal its identity.
