But the real answer to the question, "Why do you feed the birds when there is plenty of food out there?" is this: I feel like I have received a gift when the birds choose my tree to rest in, my yard to bath in, my shrubs to nest in....they know my yard is safe, they know there is food and water and shelter. I watch the birds every day, I keep track of who comes to visit and they come EVERY day, so I feed them EVERY day. I enjoy my bird friends company (okay, I like the squirrel too).
I can't even remember the last time a human (other than family) came to visit, but if you stopped by I'd at least offer you a glass of iced tea.
