When Laura and I went looking at the Yellow-crowned Night-Heron last weekend, we ran into several other birders. One of them, Hester Riches, sent me a few photos that she took of the bird at that time. Thanks for letting me share these, Hester!
I really like this photo - a great comparison of the juvenile Yellow-crowned (right) and a juvenile Black-crowned (left). The colder tones of the Yellow-crowned are really obvious here! Also note the longer legs, fine spotting on wing coverts, blunter, darker bill, and more crisp streaking on the breast.
