This is a video of a little grebe, or dabchick, ‘struggling up a waterfall at Kings Mill Reservoir.’
From RTV Oost in the Netherlands:
In Zoo Labyrinth Boekelo, this week about six rare dabchick chicks have hatched. …
To the workers of Zoo Labyrinth Boekelo, the birth of the dabchicks was a surprise. They had seen adult dabchicks coming, but they had not noted the nests.

Update 2011: that zoo is now closed.
