I am planning on participating in my first GBBC & GBD this year. and found an entertaining, front-page article on the subject in the current newsletter of one of my local Audubon societies. There also is a link for a Costa Rica virtual birding tour that gives most of the registration fee to the local guide. I think that is a terrific idea to help keep ecotourism afloat during this pandemic.
I have also placed "The Big Year" on our Netflix queue. ? We have never seen it.
