The 2015-16 Costa Rica field season starts…now! RTPI Affiliate Sean Graesser has headed out for his fifth year of research at the Nicoya Peninsula Avian Research Station with Tyler Christensen. They will once again be tracking down neotropical migrants, researching the biology of resident birds, and of course taking plenty of other tropical excursions. Sean will be sure to provide plenty of stories and photos in the coming weeks. He will again be posting things for the Roger Tory Peterson Institute of Natural History, Meet Your Neighbours, and most likely penning a few blogs again on his site for what may be the great closing chapter of their work at Nicoya.
