The average female Bald Eagle will weigh in at 12 lbs…some are larger though and could be several pounds heavier. So with all this mass, one has to be a bit dainty in the landing on ice. After they fall through a few times, the birds stop landing with a resounding thud, and put down in a more gingerly fashion…almost hovering…slowly dropping in to test the ice before they settle in for good.
