I live by a lake in southern Ontario. Every year, a number of geese will raise their young in our area. Cool watching them grow up. This year, we have a pair of Canadas raising a total of 40 young ones, all pretty much the same size. Obviously not all their own. They all stick in a tight mass around the adopted parents. They must be collecting them from other nearby pairs. Most of the other pairs this year have small broods of 2 or 3, or none at all. Most I've ever seen before attached to one pair was 15. Just wondering if others have seen similar behaviour to this extent ?
