Lovely photography of your annual visitors, we get three regular visitors to our region. The Barn swallow, Greater striped swallow and Lesser striped swallow, the later seen more regularly down here at the coast.
Soon they will start congregating on phone lines preparing to leave for summer in Europe, how envious I am of these little excellent flyers @melinda010100
We also have Tree Swallows here, and I believe Purple Martin's are a type of swallow. If will be a few months before winter is over and we have insects here for them to eat again.
