While I cautiously prowled the bank of a ditch at the Brazoria Wildlife Refuge, seeking a way to isolate a pair of unexpected basket-flowers against the sky, this juvenile night heron watched from his perch on the ditch’s control valve. His seeming curiosity — or his unwillingness to abandon a nice, sunny perch away from the alligators — gave me a chance to admire his finely-patterned feathers and large, colorful eye.
In the end, I judged him to be a juvenile yellow-crowned night heron (Nyctanassa violacea). The bill of the juvenile yellow-crowned heron is mostly black, while the black-crowned night heron’s bill is partly yellow, but — like beauty — ‘mostly’ and ‘partly’ can be in the eye of the beholder, so I turned to his feathers to make a decision.
Juvenile black-crowned night herons have larger, more discrete spots on their feathers, while juvenile yellow-crowned night herons display a finer, more distinct pattern of streaking. The white edging on their wing feathers connects to small white spots on the tips, giving them the more mottled appearance obvious with this bird.
What’s identical in both species is the pleasure a close encounter provides.
