Barn Swallow in Flight
After many frustrating attempts, I finally got a photograph of one of these Barn Swallows in flight.
The bird’s wingspan is 29 to 32 centimeters. The average wingbeat rate is 5 to 9 beats per second. Barn swallows are endothermic which enables them to be adaptable to different climates during migration. They use vocalizations and body language to communicate with each other.
They have a mutually beneficial relationship with ospreys. Ospreys offer protection while barn swallows alert them to predators.
This photograph was taken in the south of Portugal.
-Hirundo rustica
