E19. More than 55 million Americans feed birds, and it's not exactly clear the birds asked us to. Dr. Olivia Sanderfoot, Research Scientist and Project Leader of FeederWatch at the Cornell Lab of Ornithology, joins Scott to unpack what four decades of data tell us about whether feeding birds helps them, hurts them, or is really just for us.

In this episode you'll hear about:

• Why bird feeding is mostly for us, and the handful of moments when it actually tips the scales for birds
• What forty years of FeederWatch data reveal about shifting ranges, feeder dominance, and the bird that definitely should not be bossing everyone around
• How to keep your yard from becoming an ecological trap, plus the best way to feed birds that doesn't involve a feeder at all
