We have a family of swallows that like to nest under our carport every Spring. I think this is their 5th year. There are five babies in the nest and they hardly fit anymore. There are no less than 4 adults caring for the babies. Offspring from the previous season will often help the parents care for the new clutch. I risked life and limb as I stood on a chair to take these pix. Mom and Dad were swooping so close, the breeze from their wings blew my hair.
The Barn Swallow (Hirundo rustica) is the most widespread species of swallow in the world. A distinctive passerine bird with blue upperparts, a long, deeply forked tail and curved, pointed wings, it is found in Europe, Asia, Africa and the Americas. The Barn Swallow is a bird of open country which normally uses man-made structures to breed and consequently has spread with human expansion. It builds a cup nest from mud pellets in barns or similar structures and feeds on insects caught in flight. This species lives in close association with humans, and its insect-eating habits mean that it is tolerated by man. Wikipedia
