One name I have come across is Insular single leaf bat -- is that what this is? Barbados October 12, but date is probably not important, bats seems to be resident where this one was photographed.

thanks
Niels

PS: It seems that Jamaican Fruit eating Bat is the other species with that type of leaf-like structure on the nose that occurs in Barbados

I am now thinking it probably is the Jamaican f-e bat - compare https://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1157&context=museummammalogy

What about Artibeus schwartzi, schwartzi means black I think which would fit your beast and it's either a split from jamaicensis or a hybrid?

Andy thanks for the link and i additionally followed another link from there to the original paper. Fascinating!

However, one of the important facts about the schwartzi bat is a large size. The paper I linked to has a statement

In the absence of genome-scan data the smaller morphological phenotype of the Barbados population (with respect to the St. Vincent population of A. schwartzi) indicates that A. jamaicensis would be the most appropriate taxon for the Artibeus of Barbados.

The authors additionally refer to mitochondrial DNA sequences indicating that most of these on Barbados fit the original jamaicensis with only a minority of schwartzi types occurring. Could this have changed since 2012? I guess it could.

Niels,
here is a shot we took in Costa Rica, we were told that this is jamaicensis but the ears look more rounded than yours (I don't mean yours personally, Ive never seen them so can't comment ) so maybe we got this wrong?

Could it be down to geographic differences? CR to Barbados is a long way for a mostly resident species ...
For comparison, the distance is larger than Copenhagen - Malaga and a little shorter than Oslo - Malaga.

Hmm, not sure they'd have different ears shape but who knows?
