While we were at Oxford Island on our way to The Argory I took a very short video of the House Martins flying into and out of their nest. The shot below really only shows their mud made nests. Barn Swallows, Cliff Swallows and House Martins all build nests out of mud. While the barn swallow most typically builds on man-made buildings, such as barns, the cliff swallow tends to nest under bridges. These birds build gourd-shaped nests about the size of a grapefruit.
Each mud nest has a small opening to allow for entry and exit. These birds build their nests by collecting mud in their bills and mixing it together with grass stems to create pellets. Starting with a small shelf for sitting, the birds build the nest's sides around themselves. Swallows often take materials to line their nests from neighbouring nests.
