We saw a few of these as we rode in the airboat at the Florida everglades. Here's an interesting excerpt from the Cornell Lab of Ornithology:
"The Purple Gallinue is essentially a tropical marshbird that just makes its way into the United States. But some go even farther afield. The Purple Gallinule, despite appearing to be an awkward flier, regularly turns up in northern states and southen Canada. It has even been found numerous times in Europe and South Africa."
I love the colours you have captured.
