Oh, there! This is a yellow crowned night heron. I also photographed a juvenile along Riverwalk, but this adult was in the busy section at 5 pm. About 30 feet up in a tree, but not otherwise hidden. There are ducks and pigeons and sparrows along Riverwalk, but it seems that the herons are thriving too. Bravo for this strip of nature that runs through the city like an oasis, winding among the streets.
