eBird now has the ability to track and compare yard bird lists. As you can see, I'm currently ranked 13th in the state of Pennsylvania. Not bad for a 18 foot wide row home lot. Time to do more birding from my back porch--and prepare to ID nocturnal migrant call notes when the birds head north again in a few months (my best chance to significantly boost this list since I've got almost no yard to speak of).
So start tracking the birds you see in your yard on eBird. You could be a winner!
