My front yard was full of Robin's this morning and I don't know what it is this year about the Robin's but they are plentiful.  Usually I only see a few in the spring but this winter they have been seen flying all around and searching for earthworms, grubs, inspects and fruit. 

In the South the roosts are often enormous, the birds scattering during the day to feed on the fruits of sour gum, chinaberry and hackberry.   The female are slightly duller on their breast but the male is much darker on their breast area which is an orange color. 

The voice of the Robin has a variety of scolding, alarm, and call notes.  Some are loud and piercing.  The most unexpected is a thin, high-pitched hissing.  The loud caroling song is composed of 2 and 3 note phrases broken by pauses.  It has a cheerful bubbling quality, and there is a distinct change in pitch in each phrase.  The Robin's favorite song period is at daybreak, the carol often continues for minutes at a time.
