The Mallard ducks started quacking in unison which means "heads up" in duck language. lol
I looked around for a dog or cat then up to the sky & there it was! At first I thought it was just a Turkey Vulture but then I saw the white head & I knew it was a Bald Eagle. It was soaring fairly high & circled the park a few times which allowed me to adjust the exposure so that I could get some details. The sky was as white as the snow on the ground.
