my muscovey duck went missing do ducks make babies and eggs in fall or just in spring
I don't know the answer. Maybe try the Bird Watching Forum if nobody else answers here soon.

I think Moscovey ducks are a South American species. I expect they nest, around here, in Spring. They would be prey to any number of animals. Just here in NJ they would be preyed upon by fox, racoon, coyote, hawk and owl, to name some. Swimming babies would be taken by snapping turtles and even a really big bass. I lost my chickens to a neighbor's dog that has gotten loose.
