"EAGLE-EYED" - adjective - quick to notice things; observant; having keen vision.
I saw this Crowned Eagle fly up the valley below our house last week and then heard it calling ... It was perched in a tree about 40 metres from the house. With camera in hand I cautiously moved closer to try and get a photo. He was watching me while I was focused on him and when I got too close he turned and glided down into the valley.
Crowned Eagles have been nesting in our area for more than 20 years.
