Having barn swallows can be a bit messy, but they do a thorough job of keeping all wasp and hornets away from the buildings. This adult pair returned every 30 seconds with a mouthful of insects to feed the six fledglings crammed in the hand sized mud nest. They then flew away with an equal amount of baby bird droppings. | Shalom Wildlife Sanctuary | Facebook
