I saw this mom and calf on a couple of different occasions and observed that the mother is trying to ween the calf from her care. She would give it much more space than I have seen in other pairs. She would not let the calf nurse either, groaning loudly and pushing the calf away every time the calf tried to nurse. She would take the calf to the willows and have it eat from the plentiful vegetation around Schwabacher's landing.
