Grapevines and Birdnests

We are still working with the grape vines every day - right now, our mature Chambourcin grapes need to be thinned out (again).  Apparently, the late frost we had in May caused all the cordons to sprout new shoots and now we have way too much vegetation, too little sunlight and not enough airflow going on.  While we've been thinning and tying away, we discovered several bird nests:

Nest with 5 eggs inside a
flower pot in the tractor shed

 

 

This nest actually had an
outside ring of grapevine
branches for camouflage

Tiniest nest ever, with a very
small egg - just one!
