Its ducklings jump straight from the tree hole to the water or the ground after hatching.
From Goosander
Its bill carries backward-pointing horny barbs that work like a saw and stop fish escaping once caught: hence the specific name serrator, "sawyer".
It is a powerful flier that reaches 129 km/h in level flight.
