When the flock of Black-bellied Whistling Ducks swoops past overhead, they're usually going so fast that it's hard to get a picture of them.

How many ducks?

 

I got another photo of them, still not as close as I'd like, but I put it here because it's a "Look Out Below" moment. Those aren't spots on the lens beneath the duck.

There are a few more pictures of the Black-bellied Whistling Ducks on my Spoonbill page.
