Field Notes
Description:
Most birds lay their eggs at sunrise, but not robins! They lay their eggs at mid-morning. That's several hours later than most birds lay eggs. For robins, this makes good sense. Robins eat a lot of earthworms during the breeding season, and they use those early dark hours to hunt for worms because worms are most available before the sun gets too high. Robins lay their eggs mid-morning after feasting on worms. A robin can then fly over to her nest and lay her eggs easily, but most other birds seem to need a long period of quiet before they can lay eggs. Those other species can get a big breakfast even if they eat late because they don't want worms anyway!
Habitat:
The quintessential early bird, American Robins are common sights on lawns across North America, where you often see them tugging earthworms out of the ground. Robins are popular birds for their warm orange breast, cheery song, and early appearance at the end of winter. Though they’re familiar town and city birds, American Robins are at home in wilder areas, too, including mountain forests and Alaskan wilderness.
Notes:
An American Robin can produce three successful broods in one year. On average, though, only 40 percent of nests successfully produce young. Only 25 percent of those fledged young survive to November. From that point on, about half of the robins alive in any year will make it to the next. Despite the fact that a lucky robin can live to be 14 years old, the entire population turns over on average every six years.
Although robins are considered harbingers of spring, many American Robins spend the whole winter in their breeding range. But because they spend more time roosting in trees and less time in your yard, you're much less likely to see them. The number of robins present in the northern parts of the range varies each year with the local conditions.
