White-faced ibis are fairly common around the wetlands and fields in the summer, and they are beautiful birds up close, especially in breeding plumage. From a distance they look black, a bit like cormorants, so often get ignored.
Their feathers have iridescent colors - shimmering green, purple, red, brown, etc. depending on what angle you are looking from and the angle of the sun. They squawk like a heron when disturbed but normally do not seem to be too concerned with humans.
Here's a couple I saw today!
