This week on The Pulse and SciStarter’s segment about citizen science, producer Kimberly Haas tags along with local birdwatcher Pat Evans as she studies migratory bird patterns and fluxes in bird populations from New Jersey.
The Great Backyard Bird Count takes place from February 14th to 17th this year, so get started and let us know how many birds you count in the comments! Or “tweet us” (get it?) at @SciStarter when you participate!
Listen here to learn more about how this all contributes to a larger picture! Here’s an excerpt from WHYY’s related blog post:
“All you have to do is bird, either one of the four days or all four days, a minimum of 15 minutes,” [Stephen Saffier] said. “Just look out your back window, count the birds that are there in your yard. You can go to parks, you can go to schoolyards. And you tally that information on a piece of paper and then you submit it online and it all gets bundled up into this data source for Cornell and Audubon.
Recently, Science Matters, a multi-platform initiative to engage the public in STEM media, created a how-to video for those interested in participating in the GBBC this year. Their intern Margaret Carmel gives us a walkthrough.
Here’s where you can help. If you’re a citizen science researcher, project manager, or participant in the PA, NJ, or DE areas, we want to hear from you!

Is your friend or family member an ornithologist, a conservationist, or a general appreciator of the environment? How about a Baltimore Orioles or Philadelphia Eagles fan? Stanford Cardinal? Consider adopting a bird through Audubon’s gift program! (Orioles, eagles, and cardinals among a number of other birds are all available for adoption). For $30, through the adoption program, the recipient will be given a personalized card showcasing their adoption, a year subscription the Audubon magazine, and a year of membership to the National Audubon Society. Your donation will support Audubon’s programs aimed toward conserving and restoring natural ecosystems for birds and other wildlife.
The adoption program contributes to Audubon’s efforts to protect flight paths that birds use during migration, or flyways, and other important bird areas around the world. Through Audubon’s work with local chapters, conservation partners, and citizen scientists, the organization has identified over 370 million acres (more land than California and Texas combined) in the U.S. for active monitoring and restoration to ensure birds safe passage and healthy breeding. A case in point is the Atlantic flyway, which is home to roughly 150 important bird areas prioritized by Audubon. Spanning diverse ecosystems all the way from Maine to Florida, the Atlantic flyway is a passageway for over 500 different species, totaling millions of individual birds. One of the main challenges posed to the birds that depend on this flyway for habitation and migration is the populous nature of the region – although the Atlantic flyway covers a tenth of the nation’s landmass, it is inhabited by one third of the nation’s people. Urban development, climate change and overfishing have adversely affected the avian community and have rendered 40% of the resident species in need of conservation. Sadly, some species’ populations have decreased by as much as half in recent years.
This year, you can choose to adopt the Atlantic puffin, a protected bird in the Atlantic flyway and a great choice for the holiday season. Donations through the adoption program have supported Project Puffin which has restored puffins to their historic nesting habitat in the Gulf of Maine. In 1973, just two small colonies of puffins existed in Maine. Over years of transplanting puffins from colonies in Newfoundland and extensive monitoring and habitat sustainment by ecologists, there are now over 1,000 puffins in Maine. These birds, with their unique beak coloring, can fly up to 55 miles per hour (which is faster than a racehorse can run) and can dive 200 feet underwater. Puffins usually mate for life and return to their home burrowing grounds to breed, a critical factor for the success of the repopulation of the Maine site. In spite of the project’s productive results, more pufflings and adult birds died last year than in all previous years of the the project. Biologists suspect that recent increases in temperature of the Atlantic Ocean have contributed to changing fish populations that puffins prey on, affecting the viability of this Atlantic flyway resident. Audubon employs a combination of supporting science and education and habitat conservation to aid in the recovery of the Atlantic puffin population.

“On the twelfth day of Christmas, my true love gave to me…” birds! Partridges, turtle doves, French hens, calling birds, golden rings (pheasants), geese and swans inhabit this festival folk classic celebrating food and merriment. Seabirds, cousins of our dinner table counterparts, enjoy a winter migration to good eats and family too. Yet changes in climate and their relationship with man are driving population declines. Can citizen scientists help conserve our feathered friends?
The Puget Sound Seabird Survey (PSSS), in association with the Seattle Audubon Society, is enlisting citizen scientists to catalog the diversity of coastal birds along three square miles of Puget Sound saltwater habitat.
During seabird’s annual migrations, near shore saltwater habitats, such as the Puget Sound, provide valuable food and mating sites. Nearly all species of coastal birds including geese, ducks, swans, loons, grebes, cormorants, gulls, terns and alcids have experienced population declines since the late 1970s due to ecosystem changes caused by human development. Stopping to watch these graceful birds on your way to Grandma’s house can provide important population clues for local scientists.
Now in its sixth season, PSSS is the only land-based study of seabirds in the central and south Puget Sound. (Previous studies relied on aerial and marine data.) “PSSS is a scalable program that engages citizen scientists to collect significant data on valuable environmental indicators” explains Adam Sedgley, former science manager of the Seattle Audubon Society.
On the first Saturday of each month from October to April, citizen scientists are paired with experienced bird watchers and seabird scientists to identify all species of wintering coastal seabirds. Armed with your keen powers of observation, binoculars, compass and rulers; teams survey one of 82 sites along the Puget Sound using a method known as distance sampling. Directly counting each bird can be a challenge to new birders – species are hard to see and identify at a distance, poor weather conditions obscure views, and birds are often underwater. In distance sampling, citizen scientists simply line up a ruler with the horizon then measure the distance to the each bird in millimeters. Record the birds you’ve seen, their distance from the horizon, and compass bearing on PSSS’s interactive website. Using this data, scientists accurately estimate population size and health creating a snapshot of seabird natural history for more than 2400 acres of Puget Sound. This snapshot helps to inform conservation and oil spill clean up efforts.
Being a birder has never been easier. PSSS and the Seattle Audubon Society have developed excellent resources for citizen scientists including the stunning photographs by local photographer David Gluckman and an interactive website with information on all species of seabirds found in the Puget Sound region as well as their habitat and life histories. They also have an interactive map for you to explore each of the survey sites based on the most birds observed or most diverse areas.
Why not take a stop while you’re venturing “over the river and through the woods” this holiday season to watch the birdies?

Bird watching has been popular for a long time. It goes back at least as far as the 1780 bird-listing song so popular with carolers, “The Twelve Days of Christmas.” Certainly only birders would count 7 swans (a-swimming), 6 geese (a-laying), 5 golden rings (evidence of historic bird-banding practices), 4 colly birds (blackbirds), 3 French hens, 2 turtle doves, and 1 partridge (in a pear tree).
Even further back, roughly in the year 0 AD, odds are pretty good that at least one of the three wise men in the manger was a birder. It was exactly 1,900 years later in the United States when Frank Chapman turned a traditional Christmas Side Hunt into an event for counting birds and pooling their numbers instead of their carcasses. In so doing, he cultivated Christmas spirit towards sharing knowledge instead of consuming resources. Even more, he anticipated that the shared knowledge would be put to use towards conserving our feathery companions. The Christmas Bird Count, now run by the Audubon Society, is an iconic example of citizen science. To this day, many say “bah-humbug” to their holiday shopping list in order to make time for their species checklist.
And for many bird lovers, one annual tradition is not enough. People extend the Christmas spirit of the Audubon event by sharing their observations in other programs. These include Project FeederWatch (November through early April) run by the Cornell Lab of Ornithology and Bird Studies Canada, and the Breeding Bird Survey (summer) run by the US Geological Service’s Patuxent Wildlife Research Center and the Canadian Wildlife Service.
Several years ago, I realized that data from the Christmas Bird Count might shed light on a fundamental issue in ecology: competition between species in the wild. With enthusiastic colleagues, we analyzed trends of two very common species in Christmas Bird Counts for a research paper in the journal Ecology.
The hypothesized competitors were House Sparrows and House Finches. If you watch a bird feeder, you may even see these two common birds interact in ways that generated this initial hypothesis of competition. These two species fight for the same food.
House Finches are small, brown streaked birds, and the males, when on the right diet, have lipstick red feathers on their heads and upper bodies. They are native to the western US and were introduced to the eastern US in the 1940s. House Sparrows are native to Europe and only introduced to the US in the late 1800s. You are probably familiar with them as they hop around to eat crumbs in parking lots or under tables at any outdoor café. These are rough-and-tumble little birds that don’t just challenge birds their own size: they also can out-compete their much larger cousin, the Eastern Bluebird, in battles over nestboxes.
We confined the study to the Midwestern US, where neither House Finches nor House Sparrows were in their native range, neither holding a home-field advantage.
For ecologists, seeing two species fight doesn’t qualify as sufficient evidence for competition; we need to see a population-level response. In captivity, researchers can see when two species of fruit flies cannot coexist, but how relevant is that to how competition influences wild populations? In field studies, when similar species are able to co-exist, the differences in their niches are often interpreted as evidence of past competition. Ongoing competition is hard to show in the wild because it requires experimentally altering one population and looking for a response in the other and then vice versa to validate. Thus, only through field experiments that manipulate populations can we find reliable evidence of competition. After the introduction of House Finches to the eastern US, researchers began to make a case for competition by noting subsequent declines in House Sparrows. But the vice versa was needed to confirm.
Opportunity for this confirmation presented itself when House Finches declined dramatically in 1994-96 in the mid-western US due to the spread of a conjunctivitis eye disease. The spread of the disease was tracked through citizen science efforts in the House Finch Disease Survey, and continues to be tracked directly through Project FeederWatch. The rise and fall of House Finch populations from invasion and then disease, in areas with House Sparrows, created a natural experimental test of competition. There are few opportunities to look for evidence of competition among wild birds, especially at such large scales. We couldn’t have taken advantage of this opportunity without citizen science.
The long-term monitoring in the Christmas Bird Count revealed the vice versa: House Sparrows increased soon after House Finch declined from disease. And we found the same support from observations contributed to Project FeederWatch and the Breeding Bird Survey. This means that House Finches are the competitive winners, giving House Sparrows their come-uppance, except when other factors, like eye disease, turn the tables and decrease the House Finch populations.
Science is based on observation, as is bird watching. No wonder science and birding have been united by citizen science for over a century. Over 70,000 people participated in the Christmas Bird Count last year. I’m sure there will be even more this year. Let’s celebrate the holiday season with good will towards all birds.
