We hope you enjoy these Cooper's Hawk pictures that we have taken while researching raptor migration.
The first photo is an adult male that is at least two years old (After Second Year - ASY). The picture shows the typical eye color of an adult Cooper's Hawk and the prominant superorbital ridge that protects the eyes as they crash through trees and shrubs while chasing prey.
Some people think the superorbital ridge also makes them look "mean". We think it makes them look cool.
This is another adult Cooper's Hawk showing typical characteristics; rufous and white barring on the breast, the dark red eye of an adult, the dark cap (darker than the nape), and wide whitish terminal band on the tail and "flat top" head.
The next photo is an adult male that is just over one year old. If you notice, one of the feathers at the tip of the left wing (called primaries) is a new growing feather. (8th primary or 3rd feather from the end).
This photo shows a closer view of the molting primaries. Notice, that primary feathers 1-8 have been replaced with new, darker feathers, while primaries 9 and 10 (last two) are still the faded brown (older)juvenile feathers that have not yet been replaced.
This photo is a closer view of the secondary feathers that also show some older, faded brown juvenile feathers that have not yet been replaced and the new, darker, basic feathers that have replaced older feathers that have already molted.
The video shows an adult Cooper's Hawks feeding young in the nest.
And for the Cooper's Hawk enthusiast, we recommend The Cooper's Hawk: A Cross Timbers Chronicle. An excellent read by an author passionate about his favorite bird.
