Our crew is back from the field! RTPI Affiliate Sean Graesser writes that this Gladiator Tree Frog (Hypsiboas boans) was a great way to end the trip. Sitting on the river side Sean says the call is unmistakable this time of year at the gorgeous Cocobolo Nature Reserve in Panama. There will be much more to come from a very successful week, including great photos and awesome finds, from Sean and RTPI President Twan Leenders soon.
