MAMA VIEJA One of the neatest birds I regularly saw by the side of small rivers in Peru was the black-collared hawk - locally known as "mama vieja." It perches in branches overlooking water scouting out potential meals. You can hear its characteristic high-pitched call long before you see it. I got this shot on a day fishing near the village of Chino on the Tahuayo River. Read more about the natural history of this beauty at: https://en.wikipedia.org/wiki/Black-collared_hawk.
