The shrill 'rek rek rek' calls of a peregrine came from behind me as I stood in the falling light watching the sunset. I turned to see two peregrines in the air, one chasing the other and calling all the while - I guessed that the aggressor was chasing the other bird from its territory and stooped on it a few times. It then turned and came back towards me passing quickly overhead and was soon lost to the darkness. I made a few quick initial studies in my sketchbook trying to remember what I had seen and later did the above watercolor with the intention of capturing the encounter with this bird - one of my favorite falcons.
The quick sketchbook studies shown above are all about 4 x 4 inches. The Peregrine At Dusk painting is 11 x 7.5 inches, watercolor on Arches paper.
