Nicaragua Bat Surveys March 2024
In March 2024 I joined José Gabriel Martínez-Fonseca in southern Nicaragua for a portion of his nation-wide bat survey work. This was not a guided tour nor did we target any particular species, common or rare. He and his assistants were just doing routine netting and let me tag along.
In all instances we had wildlife permits and the local landowner’s permission.
We also used Sherman traps three nights with nil captures.
Over the past two years there have been questions about what equipment one can bring into the country, with brief periods when binoculars and cameras were equally unwelcome. There are horror stories of birding tour groups have all of their binos locked up for the duration of the trip.
In my case, my bags were x-rayed on arrival but not hand inspected. Once near the Costa Rican border my camera bag was inspected at a military checkpoint. This implies that bringing a thermal scope into the country is moderately risky but that in general, tourism is returning to normal. To avoid problems, I did not bring my largest, fanciest telephoto lens and tried to look like a harmless gringo. Some basic Spanish fluency helps, eg at passport control at the airport.
Except for a few officious fellows at checkpoints, overall the people themselves were as friendly and helpful as always.
José Gabriel has a truck he uses for his survey work (the “Yapok 1”), and it has “bats of Nicaragua” logos on the side. At document checks along the highway, police would say, “Oh, you work with bats, very good, very good. How many have you killed today?”
This reminds me that all of us can help with educational outreach, each and every day in the field.
We had two interesting bat records. Once we had a very leucistic / borderline albino Lesser doglike Bat, and near El Rama at a site reached by boat he netted three individuals that we presume are the first-ever live specimens of Rhogeessa permutandis, Nicaraguan Little Yellow Bat, which was previously only known from skeletal remains. DNA samples were taken but the results are still pending. All the details look good, though. If it is confirmed, it goes onto my list—not of all the mammals I have ever seen, but those mammals that I have seen and Jon Hall has not.
