Although the American Robin is presently a common bird and sometimes seen as a nuisance it wasn't always so. It was once hunted for meat (what a thought) which curbed the population a bit. Like many bird species, the American Robins population was greatly diminished by the use of DDT. Now they are back in full force.
The American Robin builds its nest from twigs, mud, and herbs, usually in a shrub or tree but occasionally on the ground.
The American Robin is not a long distance migrant. It only moves a little when it is too cold and there is not an abundance of food where it is, otherwise this bird stays put.
This bird survives by being able to use most any habitat, as well as eating most anything.
The American Robin feeds on high protein foods during the breeding season. This includes earthworms, beetles, caterpillars, and snails, as well as other arthropods. They can be quite helpful in reducing garden pests. They are quite the hunters. During the rest of the season the American Robin feeds on berries, fruits, seeds, and seedling.
The American Robin is found throughout California. It enters the desert only in the winter and leaves the high elevations in the winter.
The American Robin is found in nearly all habitats in California, including towns, orchards, and other urban areas.
The American Robin is easy to get into your garden. Some things to help them there would be some good food sources. They enjoy Toyon as well as Juniper berries. The like being ably to see predators so weeds are discouraged. One way to reduce weeds and increase earthworms is to mulch your yard. Mulch is an excellent source of bird food.
