FeederWatch, the citizen science project with Cornell Lab of Ornithology, is one way to learn birding. Along with learning the habits and characteristics of native species, I'm learning how and why these non-native House Sparrows
Passer domesticus became very successful residents across this country. They are messy, bully other birds at feeders, and harass other birds out of their nests. Unfortunately, the flock in my neighborhood seems to number 25 to 30.
