Too much of a good thing

This story on the 10000 Birds blog site takes on a controversial topic: Feeding birds. I'm one of those people who freaks out if the hummingbird food is frozen or the feeders aren't topped off. My petsitters have strict instructions about tending to the wild birds. Am I destined to become the crazy neighborhood bird lady? Will I lose sight of the fact that feeding birds can be detrimental to their health or that it attracts pests? In this story he points out two cases where huge flocks of birds, from swans to eagles, rely totally on one person. What happens when that person stops feeding? In one case, death ensues. Take a look.
