That is just incredibly cool. I'm so jealous of the wild birdies that you get to look at every day. I have a pro birder friend who has a place in Panama and spends at least a week in Costa Rica every winter doing her birder things. My brother bought a place in Costa Rica (he retired better than me). After his first trip he called to ask about a camera, and my Nikon specifically. His words "If you aren't a birder when you go to Costa Rica you will be when you leave."
Glad you are back.
Where in Costa Rica is your brother? He's kinda right about the birder in Costa Rica thing. There are just sooooo many of them, and they're unbelievably beautiful.
