It is sad. I wonder if the ducks have any other predator besides humans. Maybe alligators?

I am just wondering if they aren't being killed for sport, but for over population? They do that when the Channel Islands (off the coast of southern CA) are overrun with Goats (?? I think they are goats). Maybe I missed it, are they being killed for fun, to be mean, or for overpopulation? The article that Phred linked to said they were relocated to a farm. I think that with people not feeding them, maybe it'll help the whole situation.

What do you guys think? That is really sad they are capturing them for alligator food. Hey, do they kill alligators in Florida for being a nuisance?
