Barn swallows are captivating birds known for their graceful aerial acrobatics and distinctive forked tails. While their dive-bombing behaviors during the breeding season may leave us in awe, have you ever wondered what these avian daredevils eat when they’re not performing spectacular maneuvers? Let’s look a closer at the barn swallow, including its diverse menu and why they dive bomb us.
What do barn swallows eat?
When barn swallows are not swooping down to surprise us as we step out the door, they are busy feasting on a wide array of flying insects. These agile birds have a diet of flies, mosquitoes, beetles, dragonflies, and other small airborne prey. With their swift and precise flight, barn swallows excel at snatching insects right out of the air. The average barn swallow can consume up to 850 insects per day!
Eating Seasonal Treats
Seasonal changes affect what barn swallows eat. During the warm months of spring and summer, they enjoy a bountiful feast of flying insects, which provides them with the energy needed for their high-flying stunts. In the colder months or bad weather, they may switch to consuming larger insects, spiders, and other available invertebrates. They scour open meadows and fields for insects that rest or crawl on vegetation. Their keen eyesight and quick reflexes make them efficient insect gatherers during their terrestrial foraging.
Water and Mud for Nests
Barn swallows collect small amounts of mud and water during their flights. They use these resources to construct their characteristic cup-shaped nests, which are often found in sheltered spots like barns, eaves, and bridges. Lined with grass and feathers, these nests become a safe haven for their young.
Raising Young Barn Swallows with Adolescent Help
Parenting is a team effort in the world of barn swallows! Both male and female barn swallows feed their young; sometimes, previous brood members help with the feeding. It’s a heartwarming display of family cooperation.
Protection and Conservation Status
Barn swallows are protected under various wildlife protection laws and international treaties. Sadly, their numbers have declined in some regions due to habitat loss, pesticide use, and disturbance to nesting sites. Conservation efforts are essential to safeguard these birds and ensure their populations thrive in the future.
How to Keep Barn Swallows Off Your Property
Since barn swallows are a protected species, disturbing an active nest with eggs or young birds is illegal. It’s best to deter their nesting behavior before it begins. A little creativity can go a long way in keeping them at bay. Blocking off eaves with wood or plexiglass works wonders! For a budget-friendly option, a simple row of aluminum foil, shiny side out, strategically taped to their favorite nesting spot, can act as an effective deterrent. And you know those old, highly reflective CDs and DVDs you were about to toss? They can do the trick too!
Understanding the Dive-Bombing Behavior
During the breeding season, barn swallows may dive-bomb as a defensive measure to protect their nests and young from potential threats. They perceive humans or other animals as predators, prompting them to engage in these aerial displays to deter any perceived danger from approaching their nesting sites.
While barn swallows may occasionally startle us with their swooping flights, they are, in fact, an essential part of the ecosystem, providing natural pest control by feasting on a wide variety of insects. When they’re not dive-bombing us, these remarkable birds spend their time gracefully capturing flying insects, constructing nests, and exploring meadows for additional nourishment. Next time you see a barn swallow in flight, remember to admire its natural grace and know that they are diligently maintaining the delicate balance of nature with every insect they eat.
