I don't know if it is the same pair, but their M.O. is the same. Land in the pool, hop out groom a little, nibble on the bird feed the finches have scattered all over the pool deck.
Waddle around the pool...slowly. Mister is very vigilant.
Waddle to the koi pond. Mister must check it out first before he lets Missus go in.
If everything is to his liking in they go. They paddle around,
Take a bath, flap their wings.
They never make a nest here. Our place seems to be the courting/ honey moon spot. They will be here as a pair for a few weeks and then Mister will come by himself for a while and then he stops coming too. Every year I hope this will be the year they stay and raise their ducklings...maybe this year...
