I noticed a huge number of barn swallows over my pond today. I've had rosy red feeders in the pond since last year and I've noticed barn swallows occasionally flying around the pond and picking stuff (fish?) off of the top but nothing like today. I just stocked BG in the pond on Friday and we had a cold spell over the weekend and I'm wondering if may be my fish have died and the swallows are cleaning them up. I haven't noticed any dead fish along the shore however and you would think that I would have. Any info on swallows would be helpful. Thanks, J. Street.
