Well, that's a relief!
I worried last week when the Passover Mallards failed to show up. But I guess they just got confused by those liturgical calendars -- some years Easter and Passover fall at the same time; this year they didn't.
At any rate, here's what's outside my desk window right now. This year they're evidently Easter Mallards.
As always, they'll plod hopefully around the soggy back yard for a few days, grazing under the birdfeeders on bits knocked down by the songbirds.
Then they'll face facts, accept that this place is drying up, and depart to find some nice gooey marsh for nesting.
