Ice covered the Great Lakes. David Sibley revised his famous field guide. Laura Erickson was honored. And a Massachusetts birder pedaled across the country. Lesser Prairie-Chicken, Yellow-billed Cuckoo, Gunnison Sage-Grouse, Tricolored Blackbird, and Red Knot received governmental protections, a Rufous Hummingbird migrated by private jet, and Snowy Owls rang in the New Year.

Yes, indeed, 2014 was quite the year. We reported most of the year’s 50 most important stories, as they happened, here on our website and via our social-media outlets, and we’ll do the same in the year ahead. To stay in the know, check back daily, and follow us on Facebook and Twitter.

Here are the year’s 50 most important stories about birds and birdwatchers:

January

1. The New Year starts the way the old year ended: with Snowy Owls invading North America. One, pictured below, flew all the way to Florida. Another was captured by a falconer in Wisconsin. A third was hit by a bus in Washington, D.C., rehabilitated, released, and then struck and killed by a vehicle in Minnesota. Many owls were tagged and tracked by Project SNOWstorm.

2. Vowing to travel only by bike, foot, and kayak, Massachusetts birder Dorian Anderson sets out on January 1 on a cross-country self-powered big year to raise money for the American Birding Association and the Conservation Fund. By December 28, he had biked 17,768 miles and recorded 618 bird species, including Red-legged Honeycreeper.

3. Environment Canada announces that domestic cats — pets and free-roaming strays — are the most lethal threat to birds in the country. The animals kill 100-350 million birds in Canada annually, researchers concluded.

4. Our most endangered songbird, Kirtland’s Warbler, is discovered overwintering on a new island in the Bahamas: San Salvador. The tiny island is located 118 miles southeast of Eleuthera, where ornithologists have been studying the warbler since 2002.

5. Researchers with the Smithsonian Migratory Bird Center and the U.S. Fish and Wildlife Service’s Division of Migratory Birds report that between 365 and 988 million birds die each year from collisions with buildings, and especially windows.

February

6. Popular tour leader, public speaker, and author Laura Erickson (right) becomes the fourth BirdWatching contributing editor to receive the American Birding Association’s highest honor: the Roger Tory Peterson Award. She writes the column “Attracting Birds” in every issue of BirdWatching.

7. Extreme cold grips the Midwest, and ice covers the Great Lakes — 96 percent of Lake Erie, 95 percent of Lakes Huron and Superior, 82 percent of Lake Michigan, and 43 percent of Lake Ontario — causing Horned and Red-necked Grebes, Common, Hooded, and Red-breasted Mergansers, and other waterfowl to search for open water. Many starve.

8. As many as 142,000 birders in 135 countries record 4,296 species during the Great Backyard Bird Count. February 14-17

March

9. Hawaiian Goose, also known as the Nene, successfully hatches chicks on the island of Oahu for the first time since the 18th century.

11. The Federal Migratory Bird Hunting and Conservation Stamp, or Duck Stamp, celebrates its 80th anniversary. President Franklin Delano Roosevelt signed the act into law on March 16, 1934, creating one of the most effective conservation programs in our country’s history.

12. The U.S. Fish and Wildlife Service estimates that 304 Whooping Cranes are in the Aransas-Wood Buffalo Population, as revealed by surveys conducted on the primary winter grounds in Texas. The estimate includes 39 juveniles. March 17

13. Declaring that a single corn kernel coated with a neonicotinoid is sufficiently toxic to kill a songbird, American Bird Conservancy calls for a ban on the use of the pesticides. March 19

14. The U.S. Fish and Wildlife Service announces the listing of the Lesser Prairie-Chicken as Threatened under the Endangered Species Act. The agency says it had considered the bird to be in trouble for the past 15 years. March 28

16. Ruby, the plucky Red-tailed Hawk that won the affection of birders in Cambridge, Massachusetts, is discovered lifeless under her nest tree. Lab tests would subsequently confirm that she was killed by poisons intended for rats.

May

17. Team Sapsucker records 275 species during a Big Day that starts outside Tucson, Arizona, and ends near La Jolla, California. The total is the highest Big Day score ever reported from the region, and in North America it is second only to the record the team set in Texas in 2013. May 3

18. The first comprehensive estimates of bird mortality caused by the 2010 Deepwater Horizon disaster show that 700,000 birds died within 25 miles of shore while another 120,000 perished farther from shore.

June

In 2013, 11,046 pairs nested in 100 colonies throughout Florida, Georgia, South Carolina, and North Carolina. June 26

23. A Brown Booby visits Hansen Lake, Sarpy Co., Nebraska. June 28-30

26. Researchers with the U.S. Fish and Wildlife Service announce that prairie wetlands in the Prairie Pothole Region, often referred to as America’s duck factory, declined by 1.1 percent between 1997 and 2009. The declines add up to a loss of breeding habitat for 100,000 pairs of ducks.

27. The U.S. Fish and Wildlife Service announces that it will phase out the use of neonicotinoids in all national wildlife refuges by January 2016. The move follows an earlier decision to ban the pesticides in refuges in Washington, Oregon, Idaho, Hawaii, and the Pacific Islands. July 31

34. Two reports released days apart paint a gloomy picture of North America’s birdlife. One, the State of the Birds Report 2014, describes our birds today; the other, published by National Audubon, forecasts the effects that human-caused climate change will have in the years to come.

36. A portrait of Ruddy Ducks painted by Jennifer Miller of Olean, New York, wins the 2014 Federal Duck Stamp Contest. The image will be made into the 2015-16 Federal Duck Stamp, which goes on sale in late June 2015.

October

38. The U.S. Fish and Wildlife Service lists the Yellow-billed Cuckoo as Threatened in parts of 12 western states. Once abundant in the West, populations have declined for several decades, primarily due to the severe loss, degradation, and fragmentation of riparian habitat as a result of conversion to agriculture, dam construction, river-flow management, and riverbank protection. Kenn Kaufman described the Yellow-billed’s unusual breeding habits in our June 2014 issue.

39. Storms blow a Hermit Thrush across the Atlantic to Scotland. The species had been recorded in Britain only 12 times before.
