10 Fun Facts About the American Robin

They might be one of our most common birds, but there is plenty you don't know about this thrush. (Yep, it's a thrush.)

The American Robin is one of North America鈥檚 most familiar and widespread songbirds. Found in forests, fields, parks, and backyards across North America鈥攊ncluding Mexico, Canada, and Alaska鈥攖he robin is also the official bird of three states: Connecticut, Michigan, and聽Wisconsin.聽While many people are聽familiar with聽their cheer up, cheer up, cheerily caroling, here are some facts you might not know about this iconic American songbird.聽

1.)听There are dozens of聽different bird species across the globe鈥攃hats, flycatchers, thrushes鈥攖hat include the word 鈥渞obin鈥 in their common name. The American Robin belongs to the thrush family, which also includes bluebirds and solitaires.聽

2.)聽Early colonial settlers named the American Robin for its resemblance to the familiar but unrelated European Robin, which is smaller but also sports an orange breast and upright posture. Today, the American Robin exists in the form of seven subspecies, subtly differentiated by their body size and plumage, with the exception of one subspecies in southern聽Baja California, which sports聽pale gray-brown underparts in lieu of rusty tones.聽

3.)聽 Though known for being聽worm eaters, robins have varied聽diets. Research聽聽that American Robins mostly eat fruits in the fall and winter, and include聽more insects and worms in their spring and summer diets. Birders can occasionally spot in the late winter and early spring, thanks to fermented berries聽they have devoured.聽

4.)聽Often considered harbingers of spring, not all American Robins are migratory.聽While many northern robin populations migrate south during the winter in search of food, others remain somewhat local, forming groups that roam the countryside in search of the聽berries they prefer during the cold winter months. At night, these large and noisy聽flocks will roost in trees together.聽

5.) Robins that do migrate can cover a lot of ground:聽聽show that some birds have聽traveled up to 3,000 miles, from Iowa to Alaska, during their spring migration.

6.) Like most other migratory birds, robins聽don鈥檛 maintain pair bonds聽and often聽take on new mates each spring. At the breeding grounds, male robins put on strutting courtship displays for females. At dawn, they belt their melodious tunes, shake their wings, fluff their tail feathers, and puff their white-striped throats to entice lady robins.聽

7.) Robins can raise up to three broods in one breeding season, each time laying聽3-5聽sky-blue聽eggs聽that take roughly 14 days to hatch. Female robins pick nesting sites tucked away in thickets or unexposed tree branches, but sometimes they nest on the ground or atop outdoor light fixtures, too. The birds聽use pieces of straw, twigs, and dry leaves to build cup-shaped nests, and add moss, mud, and sometimes feathers to mend and line the interiors.

8.) Robin nests are often a target of聽parasitic Brown-headed Cowbirds, who lay聽their speckled eggs among the robin's聽eggs.聽But a found that robins are extremely efficient at recognizing and removing these unwanted eggs from their nests before they hatch and become competition for robin聽chicks.聽

9.) On average, American Robins live for 聽in the wild. Ornithologist May Thatcher Cooke maintained detailed records of banded robins in the early 1900s and noted that some individuals live聽as long as, with one wild robin living聽almost 14 years.

10.) According聽to some recent estimates, the American Robin population stands at 310 million. But these ubiquitous聽songbirds went through a rough patch when DDT use was rampant in the mid-1900s. Robins were among the avian species found to be affected by the use of this pesticide, and scientists recorded mass mortality events as a result.聽After the 1972 ban on DDT, their populations quickly recovered.

Now, urbanization, and its associated light and noise pollution are聽affecting these birds. Bright lights are making city robins sing聽their morning songs much the crack of dawn, and their songs are becoming more to overcome the din of traffic.
