I was just going to say "that's really hard to see" - you beat me to it! It's too bad the bird found your pond, but at least there's a solution that you can live with!
How many gallons is your pond? I'm going to suggest you may want to stick with smaller fish anyway, if the pictures are giving me an accurate size estimate. We have about 4000 gallons in our total system and had a dozen big koi plus a herd of goldfish. We lost all but one koi to a plumbing failure last winter and decided that we're sticking with goldfish. They all came through with flying colors. Losing all those fish was just too hard for me to take. Koi are definitely more challenging to keep - our Goldies and shubunkins are less stressful for this fish mom! We have one big koi left and he's the king of the pond now.
