Most birds I see at the feeder don't have much problems sharing. They might grab the fruit from another, but they don't cause a scene over it. The Clay-colored Thrushes are the exception. The minute they arrive, the squabbling begins and never stops until they leave. There is more than enough fruit for the Flame-rumped Tanagers, even if they voice off to each other a few times. But Clay-colored Thrushes show up and suddenly, there just isn't enough fruit. One Thrush tries to drive everyone away from fruit he isn't even eating.
