to bicycle over 10,000 miles to get over 400 species for the year. They started in their home province of the Yukon Territory, rode down the Pacific Coast, looping back around Arkansas to catch the Texas spring migration, then eastward to Florida. They dubbed this attempt a "bird year," rather than a big year. In the end, they covered more than 13,000 miles by bicycle and tallied 548 species, raising more than $25,000 for bird conservation in the process. 2014 saw the first continent-wide "green year", a big year executed with a minimum of environmental impact. In his rather extreme instance, Dorian Anderson bicycled 17,830 miles around the United States, amassing a self-powered, petroleum-free 618 species during his 365 days on America's roads. Dorian visited 28 states (some twice) during his adventure and, beyond his species total, raised $49,000 for habitat conservation. He shunned all motorized transportation for the entire adventure, refusing even ferries that would have saved him sometimes hundreds of miles of riding around various bodies of water. He was hit by a car once, and almost hit several other times, but survived the entire year without major injury. In 2021, Niky Carrera Levy and Mauricio Ossa, a couple of publicists and photographers made the first Big Year in Colombia, the country with the largest number of birds recorded in the world. They managed to record 1,453 species, the highest count of birds in one year in a single country. They traveled the 32 departments of Colombia in 21,974 miles. In addition to counting birds, they carried a message of conservation with the Colombian grebe, the only extinct species in Colombia and they got 789 children to take the oath of guardian of the birds.
