Audubon chapters everywhere invite volunteers to join the 123rd Christmas Bird Count, and that means it’s time to hone our bird watching skills for the longest-running community science project. Seasoned birders and beginners alike spend a few minutes or a full day on this annual census of birds. Those just starting to notice birds can be valuable spotters in the mobile sectors, and can quickly learn to observe the subtle differences between similar species seen from the comfort of home, where no bird feeder is required, and valuable contributions can be made with just a few minutes of counting birds.

The Bridgerland Audubon Society launched the Cache Christmas Bird Count watch circle in 1955, contributing to a tradition launched in1900 by ornithologist Frank M. Chapman who out of concern for dwindling bird populations managed to change the culture from annual Christmas bird shooting contests into bird counting contests. Bridgerland Audubon always schedules on the first Saturday on or following December 14th, and typically documents about 100 species of birds.

The Cache Valley watch circle is divided into eleven sectors, including a 4 a.m. owling sector, and includes all homes within a 7.5 mile radius from the center of the circle which is located at Main Street & Hyde Park Lane (Hwy 91 & 3600 N). The same 15-mile diameter watch circle is surveyed each December – that’s about 177 square miles, and we can use all the help we can get, especially from folks watching from home. Don’t worry if you can’t identify all of the birds you see – you will just report the ones you do recognize. You can also get help by posting photos to the Bridgerland Audubon Facebook group, where you’ll also see posts about the Dark-eyed Junco, a small dark bird with a white belly, and subspecies which include the Oregon Junco with a black hood and neck, the Pink-Sided, the Gray-headed, and the Slate Junco.

The Home Sector provides a lot of extra data on about 32 species, the most common of which are available on a one page photo-illustrated checklist on the Bridgerland Audubon website where you will also find links to the free Merlin App which identifies birds by their songs. The Visitors Bureau has a nice selection of Utah Bird field guides which are great for beginners.

Bird identification is all about learning to notice the little differences in size, coloration patterns, shape of the beak, the crown of the head, and the tip of the tail. For example a House Finch and a Cassin’s Finch may look the same at first glance, but the House Finch has streaks on the side of the body, a rounded tail tip, and the red over the eyes is more like a headband than a top hat. The Cassin’s Finch has a notched tail, red cap, and lacks those streaks on the breast and and sides. The Pine Siskin looks like a tiny House Finch but it has a hint of yellow on its wings and the beak is more delicate and pointed. Large flocks of birds can be counted by blocking off a group of individuals, counting them, and then extrapolating to the whole of the flock. Don’t forget that zero is a number to report!

Visit Audubon.org to find a Christmas Bird Count near you, and visit bridgerlandaudubon.org to join the local count sector leaders on Saturday, December 17th, 2022. Pre- registration is free but required.

The Audubon Christmas Bird Count is the nation’s longest-running community science project and it fuels international research throughout the year. Seasoned birders and beginners alike spend a day counting our local populations of bird species. Those just starting to notice birds can be valuable spotters in the mobile sectors, and can easily learn to observe the subtle differences between similar species we’re likely to notice when looking out the window from home for a few minutes.

The Bridgerland Audubon Society launched the Cache Christmas Bird Count watch circle in 1955, contributing to a tradition launched in 1900 by ornithologist Frank M.
Chapman who out of concern for dwindling bird populations managed to change the culture from annual Christmas bird shooting contests into bird counting contests.

Don’t worry if you can’t identify all of the birds you see – you will just report the ones you do recognize. You can also get help by posting photos to the Bridgerland Audubon Facebook group.

Bird identification is all about learning to notice the little differences in size, coloration patterns, shape of the beak, the crown of the head, and the end of the tail. For example a House Finch and a Cassin’s Finch may look the same at first glance, but the House Finch has streaks on the side of the body, a rounded tail tip, and the red over the eyes is more like a headband than a top hat. The Cassin’s Finch has a notched tail and lacks those streaks on the breast and and sides. The Pine Siskin looks like a tiny House Finch but it has a hint of yellow on its wings and the beak is small and pointed. Don’t forget that zero is a number! If you’re lucky you might even get creative inspiration as did one participant who didn’t see any birds but did write a poem which they asked be attributed to anonymous:

Christmas Count Lament:
I watched and watched all day,
not one bird did come my way.
Though snow gave way to sun,
still, not a single one.

No delicate song,
no fluttering wing;
no pecking or scratching
-no anything.

How less dimensional
the world would be,
if there were no bird song to hear
or fluttering to see.
– By Anonymous

The Christmas Bird Count: Connecting to our ever changing natural world

My boots crunch loudly on the snow and we pause frequently to uncover a bundled-up ear from hats and hoods to listen. We are listening for birds like the high-pitched call of a cedar waxwing, clear trilling song of a ruby-crowned kinglet, or the incessant sounds of the red-breasted nut-hatch. The bright light from the rising winter sun sparkles brilliantly on the snow, which marks the start of a full day of birding ahead in the dead of winter. I, along with many others, make these winter birding treks annually to collect data for the Christmas Bird Count, which is the longest running community science project. This count began in 1900 as an effort by an Ornithologist, Frank M. Chapman, to start a new holiday tradition to encourage people to look at birds instead of hunt them. Fast forward to 121 years later and we are still collecting data instead of dinners. The first count in the State of Utah started not long after in Provo in 1903 with many other places following suit across the state as the years went on.

The rules are simple; count all of the birds both seen and heard within a designated 15-mile diameter area over the entire day of the count which must be sometime between 14 December and 5 January. The result of these local and national counts now equates to a treasure trove of data. Every year since 1956 when the count started in Cache Valley, we observe around 90 species, though weather permitting we can see upwards of 100 species.

Data from these counts are valuable in documenting species like the Evening Grosbeak, a large vibrantly yellow-colored finch which migrates in large flocks. In the early days of the Christmas Bird Count, Evening Grosbeaks would migrate south in large numbers every few years from the Boreal Forests of Canada and the Northern U.S., to the point that they were observed in over 50% of the Christmas Bird counts across the U.S. In the late 1980’s however, their population size and ranges suddenly decreased drastically. In our data from the Cache Valley Christmas Bird Count we see this trend echoed with just 3 Evening Grosbeak observed in 1980 jumping to 119 seen the following year. That record was broken again though 2 years later and then shattered in 1987 with 721 Evening Grosbeaks seen on the single count date. The very next year the numbers plummeted with only 5 individuals seen. Numbers have since remained low until 2017 when we saw 282 Evening Grosbeaks. One theory about these dramatic fluctuations in population size and ranges is thought that it mirrors the abundance of their prey, spruce budworms. It is also hypothesized that deforestation and climate change play a role in these fluctuations of their population as well as their prey.

Observing these species and increasing this treasure of data is important for painting a picture of species movement and in addition, how species are responding to a changing climate locally and globally like the Evening Grosbeak. This massive data collection cannot be achieved by only scientists however, the participation of community members, like you and me, is necessary for not only the collection of more accurate data, but also for opening our own eyes to the natural world around us and getting to know the space that we occupy. Birding is a great way to connect to the outdoors and the Christmas Bird Count is the perfect excuse to get outside, especially this winter. Participation can be as simple as watching out your own window, joining a caravan, in separate vehicles this year to maintain social distance, or trekking through the snowy mountains from sunup to sun down. Visit Audubon.org to find a Christmas Bird Count near you to join this historic count.

Christmas Bird Count 2019

On December 14th, I will join several others for an exciting day of counting bird species and numbers in our lovely, snowy valley. The numbers will be entered on a database that will be shared globally.

Count Data:
The data collected by observers over the past 120 years has allowed researchers to study the long-term health and status of bird populations across North America. When combined with other surveys such as the Breeding Bird Survey, it provides a picture of how the continent’s bird populations have changed in time and space. This long term perspective is vital for conservationists. It informs strategists to better protect birds and their habitat, and helps identify environmental issues, with implications for people as well.

The count has special significance for our changing climate’s impact on birds which is disrupting populations and their spacial distribution that are changing at an accelerating rate.

The report:
Audubon’s 2014 Climate Change Report is a comprehensive, first-of-its kind study that predicts how climate change could affect the ranges of 588 North American birds. Of the bird species studied, more than half are likely to be in trouble. The models indicate that 314 species will lose more than half of their current range by 2080. Adding to this, a recent study by the Cornell Laboratory of Ornithology reported a 29 percent decline in North American bird populations since 1970.

142 species of concern are found in Utah including our state bird, the California gull and our national symbol, the bald eagle. Averaging the most recent 10 years, Cache valley has seen 16 species increase and 11 species decline. Of course we would need a much broader sweep to know the true story of these species, but our data may play a significant part in the overall analysis.

Audubon’s Climate Initiative, encourages its members to take steps to address the climate change threat in their backyards and communities. Visit their website at audubon.org for how to take action.

Many Citizen Science programs exist for families to participate in- https://www.birds.cornell.edu that have generated reams of data over many years showing the species diversity and abundance of birds in North America and globally. Our valley Christmas Bird Count occurs next Saturday, December 14th. Contact bridgerlandaudubon.org for details. Always a good time gathering important data!

And please, keep those bird feeders full as we enter the coldest month of the year!
