Songbirds migrate at night to avoid predators, air turbulence, and daytime heat. Down here on the ground we are unaware of the miraculous and essential voyagers flying up to 10,000 feet above us, but thanks to dedicated scientists collaborating for years on end we have free access to the data and graphs of these massive population shifts. The BirdCast Dashboard uses weather radar to track bird migrations, providing real time data showing peak migrations at the website dashboard.birdcast.info.

Did you know that World Migratory Bird Day is celebrated in May and October? Those are the peak months for spring and fall migrations, and the magnitudes of those flocks are considerable. Two thirds of songbirds migrate at night, and on the evening of Sunday, May 15, 2022, one million one hundred and fifty one thousand five hundred (1,151,500) birds crossed Cache County, Utah! Yes, 1,151,500 birds crossed Cache County, Utah, in one night!

It’s important to know when migrations are occurring because skyglow from artificial lighting causes bird disorientation and millions of bird fatalities each and every year. The declining bird population is problematic for many reasons, not least of which because some of the most intrepid travelers like the three-inch-long Rufous Hummingbird, which travels 3,900 miles each way from Alaska to Mexico, are keystone species with ecosystem services such as pollination and consumption of pests such as aphids and mosquitoes.

The Bobolink travels 12,500 miles to and from southern South America every year – those imperiled birds breeding at the west end of Logan may travel the equivalent of 4 or 5 times around the circumference of the earth throughout their lifetime. They come to Cache Valley for the habitat, stay to raise their young, and then head back to their distant winter feeding grounds.

A few top-notch steps toward bird-friendly living include the prevention of light trespass and skyglow, especially from 11 p.m. to 6 a.m., March – May, and August – October. Close curtains to prevent the indoor light from escaping, and avoid blue light outdoors – choose warm white or amber lights, and shield light bulbs to direct light downward. Motion-activated light bulbs are a great way to safely light the way while cutting down on unnecessary outdoor lighting, especially since there’s no clear scientific evidence that outdoor lighting reduces crime. Excess light, on the other hand, is a crime, and light trespass is an enforceable infraction. Light pollution is harmful to humans and deadly for birds.

Logan Mayor Holly Daines signed a Proclamation to Dim the Lights for Birds at Night because reducing skyglow and light trespass saves energy and birds by reducing the often fatal disorientation caused by artificial light.

Dark Skies are filled with bright stars, so by jingles, what say we all “Dim the lights for birds at night!”

A Surprise visit with Cache Valley’s distant bird relatives

Awhile back, I was riding my bicycle along country roads in Cache Valley, when suddenly 6 unusual looking chicks ran across the road in single file right in front of me. I slammed on the brakes just in time as the chicks disappeared down the farmhouse driveway on the other side of the road.

I got off my bike and ventured partway down the driveway. Suddenly I found myself face to face with a fully grown peacock. This distant relative of Cache Valley’s native birds seemed quite at home in the shady backyard. As I glanced around, I realized it was his home. From where I was standing I could see at least ten more peacocks and peahens.

Then I noticed the farmer sitting in his truck at the end of the driveway. He beckoned me over and gave me the whole story.

Many years ago, he had gone to Idaho and purchased a peacock and a peahen. The peahen ran off, so he went back and got another pair. This time it worked. The pair produced a nest full of eggs which the peahen diligently sat on for four weeks. She then tended the baby chicks for the week it took them to learn to fly up into the relative safety of the trees in the yard. The small family made itself at home, settling into a routine of spending their days on the ground and their nights in the trees.

Occasionally an owl or a racoon would take their toll, but these hardy birds proved they could not only survive but thrive. Knowing that these birds originally came from India , I was amazed that they could withstand the bitter cold of Cache Valley’s winters. Perhaps it helped that the farmer had a kindly wife, who would throw out some cracked corn, an occasional cup of cat food, and – on very special occasions- some hot dogs.

Peafowl are omnivores, and on this sunny day I could see them pecking away to their heart’s content in the adjacent grain fields. Luckily this band of birds avoided the fate of the six peacocks who used to free roam the zoo in Logan’s Willow Park. The zoo birds caught the bird flu virus in 2022 and all of them died.

I told my new friend, the farmer, that I was surprised how the females didn’t look the least bit like the males. The peahen is much smaller and is a rather drab brown. He explained that the peahen needs good camouflage because she lays her eggs on the ground and then has to sit there for four weeks with absolutely no help from the male.

The farmer invited me to take as many pictures as I wanted. So I pulled out my cell phone and stepped closer to the birds. That’s when I found out just how fast they can run. They stepped away and out of sight almost before I could blink. Peacocks have been clocked running as fast as 10 mph.

It wasn’t mating season, so the peacocks weren’t fanning out their tails and trying to impress the females. But I was already completely impressed to simply find out there are 200 feathers in the peacock tail. On top of that, the peacocks molt. Each year all 200 tail feathers fall out, and the peacock has to regrow them. No wonder the colors stay so bright!

This is Mary Heers and I’m Wild about all the birds who make themselves at home in Utah.

My morning outing was bedazzled by masters of their aerial universe. Their agility is beyond imagination, capturing their prey with a gaping maw while flying at maximum speed, winged bullets ripping through the air. The swallows and swifts are truly marvels of aerodynamic design, with a pilot whose abilities know no bounds. They rival bats and dragonflies in their ability to capture insects while in flight: barn swallows, tree swallows, cliff swallows, violet green swallows, bank and rough wing swallows, white throated swift, all found in our beautiful Utah.

I watch them drink while in flight, as I have hummingbirds, another remarkable aerialist, skimming the water surface with beak scooping in. If you rarely see them on the ground, they will be resting on their stomachs, lacking abilities to stand, hop, or run. Their legs atrophied from spending most of their lives on the wing.

Two species of swallows construct elaborate nests from mud. If you visit a bridge, you may find a long row of cliffs, wallow gorge-shaped nests attached to the bridge underside above the water. The nest opening is near the same diameter as the bird’s girth. Young birds may be slightly larger than adults, making their maiden flight a bit difficult as they squeeze through the narrow exit. Their mud nests are made of 1000s of BB-sized pellets glued together with a mix of bird saliva and mud. Both add plant fiber, strengthening their adobe nests. Barn swallows construct cup-like nests on flat surfaces, oftentimes above a door, which makes it a bit tricky to avoid getting nipped by a parent as one passes through.

Swallows engage in elaborate aerial courtship displays to attract and bond with a mate. The male will pursue the female in flight, often performing swoops, dives, and glides to showcase his flying skills. If interested, the female may reciprocate by mirroring the male’s maneuvers. The pair may continue these synchronized flights throughout the breeding season to strengthen their pair bond.

Swallows hold significant cultural symbolism in various native traditions, often representing renewal, hope, and transformation. They are featured in numerous myths and stories, reflecting their importance in spiritual and ecological narratives.

Beyond swallows, incredibly important natural pest control, their presence is also a key indicator of environmental health, reflecting the condition of wetlands, grasslands, and open habitats.

Swallows by day, bats by night, both critical for controlling insect populations. With our crashing insect numbers due to insecticides, habitat loss, and a rapidly changing climate, my concern for the future of this specialized bird family continues to rise.

Climate change, with rising temperatures, altered precipitation patterns, and increased frequency of extreme weather events, are disrupting ecosystems. This impacts the availability of food and nesting sites, altering the timing of insect emergence, potentially creating a mismatch between the availability of insects and the breeding season of swallows. As temperatures rise, suitable habitats may shift northward, forcing populations to relocate or face extinction.

This is Jack Green for Bridgerland Audubon Society. I’m wild about these winged bullets of beauty.
