I just took a bunch of pictures of some content, feeding geese and I saw almost as many birds facing into and perpendicular to the wind than there were birds facing into the wind. It'll differ from early/regular-late season. In my experience, most birds when resting in the extreme cold/snow will put their breast into the wind to keep the wind crom getting up under their feathers and robbing away body heat but any other time, when all the birds are facing into the wind, they usually have their heads up and are getting ready to bug out as something just spooked them.
