And then there were four . . .

I'm pretty sure this is the pair of Canada geese that had five young hatch out recently - however, this morning there were only four.  The other pair with the single gosling were feeding on the little round island, while several odd fellows were having a noisy discussion in the water - which these two were keeping an eye on.

Postscript  21 May - Thankfully, I was mistaken in thinking the above family was the one that originally had five young, as this morning I met all three families together: one with five, this one with four, and the third with a single duckling.
