Pepper is a 6 month old wild-hatched mallard-cayuga at the lake. He has six siblings and seven cousins, so he knows he's a duck and not a human or a dog, etc. I think I've seen Pepper fly, but I'm not sure. I also think one of his brothers, another hybrid, doesn't fly that much, either. Both are not very bulky and have good flying to body ratios, so they could probably fly if they want. The thing is that Pepper really seems to enjoy watching other birds fly. When he's not grooming, eating, or sleeping, he's watching birds flying around. They can be either his siblings, pigeons, seagulls, whatever's in the air. It's not like he's watching for hawks, more like studying the other birds. With other ducks, he'll watch as they fly over and land with much intensiveness. His non-flying brother doesn't pay any attention to anything flying around. Here is a photo of Pepper watching some pigeons flying around behind him. He didn't start doing this until he was old enough to fly. Do your ducks to that?
