Birds Go Buggy!

WE are in the middle of Summer on the coast which means it’s time to go to the beach, have cookouts in the backyard, enjoy outdoor festivals, dabble in gardening and make all kinds of outside fun we’ve been chomping at the bit to do, but it also means dealing with lots of pesky bugs! Summer becomes very buggy for most of us, so we need all the help we can get to stave off menacing insects that annoy, frustrate or bite us! The nursery volunteers at the Outer Banks Wildlife Shelter in Newport are currently helping raise and staff the Army of birds we call insectivores who will eagerly and proactively keep those nasty bugs away from us! A great many birds eat a great many bugs; bugs that do harm to our plant life, as well as, annoy the crap out of us, but we should consider ourselves lucky that numerous birds come to our rescue as they feast on the great flood of insects and other cold-blooded vertebrates that become active during the summer months. Rose-breasted Grosbeaks, Scarlet Tanagers, Warblers, and other “canopy” birds feed on caterpillars that eat the leaves of trees. As soon as tiny insects hatch, the bugs begin feeding on the tiny soft leaves as they begin opening, and migrating birds and eventually, our annual hatchlings that fledge or songbird “raise & releases” from the shelter, will arrive just in time to recognize those bugs as dinner! Birds feed on big caterpillars, beetles, grubs, and other medium and large insects and spiders they find near the ground. Blackbirds, bluebirds, sparrows, crows, wrens, and other birds get a lot of protein by hunting and catching these same bugs. Red-winged Blackbirds eat both seeds and insects. Some birds, such as swallows, swifts, nighthawks, flycatchers, some warblers, and Cedar Waxwings scoop up insects flying in the air. Swallows, swifts and nighthawks will fly for hours at a time to catch insects on the wing. Flycatchers, warblers, and waxwings flutter out from branches when they spot a succulent insect and gobble it up! (There, that’s a few mosquitoes or flies that will not be landing on you!) Chickadees, nuthatches, creepers, woodpeckers and the Black-and-white Warbler find insect eggs, larvae or pupae in the crevices of tree bark. Woodpeckers can hear bugs chewing within the wood and dig them out! Those insects can do major damage to our trees. We usually think of hummingbirds as miniature, buzzing birds we provide sugar water or nectar for in our window feeder, but the truth is Hummingbirds get most of their nutrition and proteins by picking tiny aphids and other chewing insects from the surfaces of flowers and leaves and by snatching very tiny flying insects such as gnats in midair. Some people feed hummingbirds and small fly-catching birds by setting out chunks of banana and melon in a small mesh bag because they notice the immediate interest hummingbirds show, but it’s really the tiny fruit flies that swarm the fruit that they really want. Some birds, called generalists, eat a wider variety of insects than others. The Yellow-Rumped Warbler is an example of a generalist. Watch out bug, whatever you are, YRWs will not discriminate, and they will eat you! The top songbird insectivores in our coastal North Carolina airspace who help humans de-bug immensely are the petite Chickadees and Carolina Wrens and medium-size birds; American Robins, Northern Mockingbirds, Purple Martins, Chimney Swifts and Flycatchers. The Chickadee’s favorite snacks are beetles and caterpillars, flies and wasps. Wrens prey on ants, millipedes, beetles and grasshoppers. Our American Robins eat a wide variety of insects but are usually noticed most when tugging earthworms out of the ground. Mockingbirds are quite territorial and aggressive when it comes to hunting and prey mostly on grasshoppers, beetles and tree ants. You may see Purple Martins zooming through the sky during early morning or at dusk. They feed mainly on flying insects and occasionally, fire ants. Also, high in the sky, you may hear the chattering of Chimney Swifts who are putting a huge dent in your mosquito population. A group of Swifts in your area will eat up to 12,000 mosquitoes, termites, flies and other insects every day. Although omnivores, Flycatchers and Brown Thrashers add a huge portion of flies, spiders, moths, beetles, caterpillars, grasshoppers, crickets, cicadas, sow bugs, bees and wasps to their diet that includes fruits, nuts and berries. If you have any of these birds nearby, you can be sure they are helping lessen the pest populations near you and your home. If you are a gardener, maintaining your garden won’t be as great a chore due to the natural and most perfect pest control you can ever have, insect-eating birds. These birds are of vital importance to our ecosystem and must be protected. Scientific research and resulting data show that the total biomass of wild bird-consumed insects amounts to between 400 and 500 million tons. Wow! On the average, individual birds consume more than 100 times their own body weight in bugs. That figure is amazing because it’s roughly equivalent to the weight of meat and fish consumed each year by humans. Many of our insect-eating bird species are declining or endangered due to habitat loss, widespread pesticide use, hunting, infrastructure mortality and predation by free-roaming cats. If we can not arrest the threats to these birds, the invaluable ecosystem services they provide will be lost forever. We need more near-natural forested areas for many songbird species, rather than tree plantations that only support a few species. It can be overwhelming to look at the global picture of this dilemma, but we each can do something where we are with what we have. Protect and value your backyard birds. The young songbird insectivores being raised at the Outer Banks Wildlife Shelter now, will be coming to help you soon and rid your yard of damaging and pesky bugs. Please, welcome and cheer on these little bug zappers!

best always,
