The Christmas Bird Count is a Most Wonderful Time of the Year!

When the winter chill sets in, that’s my cue to start filling the suet feeders, plug in the heated bird bath, and keep the Black Oil Sunflower Seed in stock for the grand variety of birds which visit my home through the Winter. I feed the birds because I know that my visitors will have better success in raising their families next Spring, but also because they are such fun to watch! Just yesterday I was mesmerized by a Downy Woodpecker taking black oil sunflower seeds one by one from the hanging squirrel-proof bird feeder, flying onto the deck railing, and hopping along about six feet to place the seed in a knothole serving as a mortar to the beak pestle, thus gaining access to the tasty seed inside the hard shell. I immediately wondered if this behavior might qualify as tool use, but suspected it would not meet a strict definition. Sure enough, this clever problem-solving activity is not considered to be tool use, but it is no less fascinating!

This is a great time to discover the joy of bird watching and contributing to community science. The annual National Audubon Society Christmas Bird Count is hosted by many organizations in many locations, with a single day selected between December 14th through January 5th. The Christmas Bird Count database was established by Frank Chapman in 1900, when holiday shooting parties were replaced with counting parties as a proactive response to the noticeable decline bird numbers.
Cache Valley (Logan) Utah Circle 125th Annual Christmas Bird Count Visit BridgerlandAudubon.org
The Bridgerland Audubon Society Christmas Bird Count is always hosted on the first Saturday on or following December 14th, and we have been contributing Cache Valley, Utah data to the National Audubon database since 1956. You can watch from home if you live within the 15-mile diameter watch circle area centered at Main Street and Hyde Park Lane – that is if you live within 7.5 miles of the intersection of Hwy 91 & 3600 N, which includes all or part of Amalga, Smithfield, North Logan, Hyde Park, Logan, Logan Canyon, River Heights, Providence, Mendon, Benson, and unincorporated Cache County. Check the interactive map on our website to determine if your home is inside the watch circle. There’s limited space available with the wandering watch groups, too.

Even if you only see the occasional American Robin or Magpie, please do consider participating in a Christmas Bird Count near you. We welcome newcomers and beginners, and hope that you will enjoy contributing to the longest running community science program which provides data for scientists worldwide.

For identification assistance you can post photos on our Facebook group. Please don’t forget that Zero is a number – we want your final report even if you didn’t see a single bird outside your home. Consider hosting a cozy watch party, sharing hot chocolate with friends and neighbors while sharpening observation and identification skills, keeping hearts and minds full and growing in wonderful ways.

For more information check our website to register at no cost at BridgerlandAudubon.org – that’s Bridgerland Audubon A-U-D-U-B-O-N dot org.

Birdwatching is a fun hobby for all ages and it is a great way to connect with nature and increase self-efficacy, so let’s discuss the benefits and the importance of a safe environment for feeding our backyard birds. First, the benefits of supplemental feeding, and second, preventable deaths from cats and window collisions.

Supplemental food and water are important ways we can reduce stress for backyard birds, especially through the winter months. Sites with bird feeders attract more birds over time than those without feeders, and the birds are in overall greater health than birds at sites without feeders. A higher percentage of chicks hatch at sites with bird feeders, and the survival rates are significantly higher, but supplemental feeding must be done in a safe environment.

Free ranging domestic cats and window collisions are leading causes of bird deaths in North America. The American Bird Conservancy estimates that outdoor cats kill approximately 2.4 billion birds every year in the United States alone. Approximately one billion birds are dying from window collisions each year in North America – that represents about ten percent of our birds dying from crashing into windows (1), and combined, that’s over three billion fewer insect eaters, fewer pollinators, fewer seed spreaders, and fewer parents for the next generation.

Cats should be kept indoors, and windows should be treated, especially if they reflect trees and shrubs. If you have seen a ghostly bird imprint or heard the sickening thump of a bird hitting your windows, then those are windows in need of treatments such as screens, translucent UV tape, or even tempera paint designs, because even birds that manage to fly away have potentially life-threatening internal injuries. Feeders less than 3 feet away don’t allow birds to build up too much speed before they collide, so it’s good to put feeders and birdbaths 3 feet or closer to a window or greater than 30 feet away.

Feeders placed on or near windows have the added benefit of being easy to access and monitor. In addition to a window suet feeder, one of my favorite window feeders is actually a clear plastic suction-cup toothbrush cup holder from the dollar store – it’s easy to clean and there’s no need for binoculars!

In addition to enhancing a backyard bird watching hobby and improving bird health and survival, the ripple effects of feeding birds, keeping cats indoors, and preventing window collisions include pest control in our gardens where birds feast on slugs, snails, aphids and grasshoppers. I for one particularly appreciate Black-billed Magpies when they remove wasp nests from my house! The Bridgerland Audubon website has tools, coloring pages, checklists, and science-based information on window collision prevention. Solutions can be as simple as the careful placement of bird feeders and keeping cats indoors. Find us at bridgerlandaudubon.org, that’s Bridgerland Audubon – A-U-D-U-B-O-N dot org.

Peak Need for Dark Skies
and the Mantra to
Dim the Lights for Birds at Night

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.

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!
