I don't know anyone who doesn't instantly fall in love with barn swallows (Hirundo rustica). They are attractive birds which eat flying insects and have a particularly aerobatic flying ability. I enjoy watching them flitting about the property, admiring their athleticism and thinking of all the mosquitoes they must be eating. As the evening draws near, there's a shift change, and the equally aerobatic bats take over the flying insectivore niche.
We have one particular building with an overhang, and the swallows love to build their nests underneath this structure, plastering their mud nurseries under the beams. Whenever we check on this building in the course of our job duties, we are greeted by the enchanting young birds:
Soon, these little beauties will be joining their parents on the wing, zipping about in zig-zag fashion, gobbling up mosquitoes in a particularly balletic fashion. They are sure to enchant me for a few more weeks, before flying south to Central or South America, and for that (and the pest control work), I am grateful.
