Some Mourning Doves stopped by to visit our bird feeder but settled with eating snow.
I don't think the boldness of the Chickadees and Cardinals kept the doves from the feeder... the doves were just thirsty.
Oh, you probably remember taking a lick of snow from your mitten... and the tingle of the cold, melting snow on your lips, cheeks, and the tip of your nose. If so, you can relate to the left dove in the photo below. Somehow the snow clings to other places besides the tongue.
At least if you have plenty of food to digest to use to make the heat to melt the snow.
