Ducks used to be the main attraction at the pond in a park-like cemetery in my neighborhood. Several generations of area children have squealed in delight while tossing chunks of day-old bread to the quackers. Now the chunks are more likely to be snatched up one of the geese that have taken over the pond and outnumber the ducks about ten to one.
With a hundred or more Canadians cavorting and honking (or posing!) on a warm, sunny day, it was easy at first to miss one goose that wasn't like the others.
It was honking in a different pitch, as if in pain or distress, and frantically running back and forth under a sapling at the water's edge. Instead of a black neck, its swan-like neck was totally white except for a brown stripe at the back.
Never could get it to face the camera, so you're seeing what I saw - its back and a heavy, egg-shaped bulge under its rump. From this and what sounded like cries of distress, ol' City Girl here assumed it was a female Canadian, in the throes of "labor" to birth that egg.
But if this were the coloring of a female Canadian, in a flock this size shouldn't there be others?
Back home, by Googling various search terms, I learned my Goose Of A Different Stripe is a Chinese Brown (a.k.a. Chinese Swan), but didn't find out if the bulge is indicative of an egg-carrying female. Since geese mate for life, the frantic honking could very well be normal for a male trying to locate its lost mate.
Here's a shot of it in the water:
The remaining mystery is how he/she came to be here in the park at all, the lone specimen among a flock of Canadians.
As the photo below shows, some of the Canadians are quite the little hams. All I had to do was raise the camera to my eye, and he (she?) walked right up and posed!
