Hi, I could be interested in joining you on one or more of the potential trips you list in your post - Quintana Roos (if I can get a cheap flight), Chile, Africa (if southern), and Brazil (if northern). I'm 50s, from London in the UK and have birded all over. Maybe you can let me know if you're looking for anyone else to join on you, now or whenever the plans develop?
Cheers
Rob
