Bulbous Buttercup

This afternoon I spent some time in the yard working on a flat tire, easily distracted by the mournings doves and chipmunks searching out little bits of whatever in the dirt road. There were so many species of birds singing. I don't know calls so I'm at a loss to describe them by name.  I then noticed this Bulbous Buttercup, Ranunculus bulbosus, grows by my doorstep. I walk by it every day but hadn't paid it much mind.

I'm pretty sure on the species based on comparison at the Connecticut Botanical Society web site.

Cuckoo spit, from spittlebugs!
