Young robins can be confusing if only for a minute or two.
This one doesn't have the typical black head and red breast of an adult.
It has a disk like patch on its cheek reminiscent of several other thrushes.
Robins, like some other birds have regional variations of songs.
We once followed an odd looking bird with a some what familiar song for 30 minutes in South Carolina.
It turned out to a robin.
Well a birder can't follow a robin for 30 minutes trying to identify it so it became a black headed, red breasted American thrush
Robins eat a lot of fruit in fall and winter. When they eat honeysuckle berries exclusively, they sometimes become intoxicated.
The oldest recorded American Robin was 13 years and 11 months old.
