Subject: Re: [VTBIRD] chickadee count in Etna
It has been a while since the trip to Costa Rica with Jeannie and Ted, but
I still have fond memories. I thought of you after watching a presentation
on Black-capped Chickadees by David Hot given to members of Green Mountain
Audubon Society. You might find it interesting given your banding of these
guys at feeders. Here's a link .

I hope that you are well and surviving this pandemic. After almost a year
of being careful, my wife and I have been hit by this awful virus. It is
no fun! Take care and stay safe!
