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.

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!

It might be worth checking one’s mental state if they were to spend many hours in frigid temperatures hoping to find a bird. There are many of those crazies in our valley here in northern Utah. Citizen Scientists they call us. After all, we do follow strict protocol that defines boundaries, time and what is legitimately called a bird siting or sounding. Yes, there are errors in counts when a flock of European starlings darken the sky, or when trying to identify a distant raptor, that is scarcely more than a black dot in the heavens.

Called the Christmas Bird Count, this event is the longest citizen science program in the world, where data has been collected since 1899. Here in Cache Valley it began in 1955. It occurs throughout the state and world with many countries participating. Visit your local Audubon chapters if you care to be involved. Wasatch, Salt Lake and St George all have chapters. Bear Lake, Vernal and Provo also do counts. And I am sure there are others in your area if you inquire.

Along with the fun it brings, the count has special significance for our changing climates’ impact on birds, which is disrupting populations and their spacial distribution are changing at an accelerating rate.
The data collected by observers over the past 118 years has allowed researchers to study the long-term health and status of bird populations across North America and Central and South 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.

Audubon’s Common Birds in Decline Report revealed that some of America’s most beloved and familiar birds have taken a nosedive over the past forty years.

142 species of concern are found in our state, including our state bird, the California gull and our national bald eagle.

If you aren’t up to braving the elements, Project FeederWatch and Great Backyard Bird Count are other options you may find by googling. I’m hoping for good visibility and temperatures above zero as I prepare my optical instruments and hot chocolate.

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

Project FeederWatch is a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. FeederWatchers periodically count the birds they see at their feeders from November through early April and send their counts to Project FeederWatch. FeederWatch data help scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance. https://feederwatch.org/

Launched in 1998 by the Cornell Lab of Ornithology and National Audubon Society, the Great Backyard Bird Count was the first online citizen-science project to collect data on wild birds and to display results in near real-time. https://gbbc.birdcount.org/about/

Audubon’s 118th Christmas Bird Count will be conducted this coming season, with all counts held between the dates of Thursday, December 14, 2017 through Friday, January 5, 2018.

Climate Change and the Christmas Bird Count

On December 17th, 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.

The Christmas Bird Count began on Christmas Day in the year 1900 when ornithologist Frank M. Chapman, an officer in the nascent Audubon Society, proposed a new holiday tradition—a “Christmas Bird Census” that would count birds during the holidays rather than slaughtering them, which had been the past ritual.

The data collected by observers over the past 116 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.

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.

Audubon’s Climate Initiative, the organizational response to this threat, taps into its members’ love and commitment for birds to build population resilience and demand solutions to slow the pace of warming. Audubon is encouraging 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.

The Environmental Protection Agency has included Audubon’s climate change work from CBC data as one of 26 indicators of climate change in their 2012 report.

In 2007, CBC data were instrumental in the development of Audubon’s Common Birds in Decline Report, which revealed that some of America’s most beloved and familiar birds have taken a nosedive over the past forty years.
142 species of concern are found in Utah including our state bird, the California gull and our national bald eagle. Averaging the most recent 10 years, our valley has seen 16 species increase and 11 species decline.
