Hello bird lovers! I’m new to the forum and am interested in learning more about swallows! We moved here to the southwest of United States 5 years ago. We have had swallows before and have hoped they would pick us for a new home and they did this year. We are so excited to share our back porch with them but they came and spent many days discussing the location of their nest. They finally decided and built a nest, slept in it a couple of nights and now have seemed to have disappeared. 😢 We can’t figure out why, we are hoping someone has some insight.
