Bob and I went out fishing yesterday with friends on there pontoon boat to a near by lake. Fishing was not too plentiful but by trolling around the lake we came to several bridges. Under the bridges were these nest built by cliff swallows. Then nests are made with mud and as you can see the babies are peeking out. They will build their nests under bridges and on the sides of cliffs there by their name. Barn swallows do the same thing on the eaves of barns.
Thanks for looking!
