I love birds, and have multiple nest boxes and feeders around my home. I've learned to identify my backyard birds by using The Cornell Lab of Ornithology website:

I'm also working on a funny animated cartoon about birds with some factoids thrown in:

I think birding is a great way to introduce kids to the idea of land conservation and habitat preservation for wildlife near human populations. Birds are able to co-exist well with us within suburbs and cities if there are large parks or nature preserves nearby. Humans obviously also benefit from having a place to go near their homes that can bring them closer to nature, which can be both mentally calming and physically invigorating. And of course other animals and plant species would benefit from protecting and/or expanding park land.
