More about telling male and female Ospreys apart

Female Osprey (L) has a streaked breast. Male (R) has an almost clear breast.
The difference between the female Osprey's breast marking and the male's relative lack of breast marking is clear in this image from the Osprey cam.

If you are watching the nest cam and cannot see the breast of the Ospreys, these two have another distinguishing feature. The male has a distinctive partial eye ring that breaks up the dark eye stripe behind the eye. The female's eye ring is narrower and in some views almost invisible.

The male's partial eye ring is more pronounced than the female's.
