Birds in the Winter - American Robin

The American Robin, yes, this harbinger of spring can actually be found here all year round. 
It's an interesting story... Most are familiar with the robin in the spring - as the ground thaws and the earth wakes up with the rains, you can find them hopping around lawns happily gathering worms and insects (they opt for insects over worms). Then fall comes and these birds slowly begin to change their diets to one more fruit and berry based. Once winter is upon us and food is scarce, you can find robins letting their territorial guards down to flock together in orchards and other areas with high fruit concentration. Yes, some migrate south for the winter but that is more due to a lack of food supply than the cold. Then spring comes around, the flocks of fruit enjoying robins split up, everyone goes back to their territories (backyards, parks, etc) and mating season gets underway.
