Might not this be explained if the F1 Calocitta x Psilorhincus is sterile? 2) Some vague evidence that the strange jay has been seen in small flocks - Perhaps they wouldn't be expected if the thing is a hybrid - or perhaps it would. In any case the info. on this point is poor. Almyer's lone bird is the only definite observation we can trust. I favor #3 as an explanation but #2 is still a good probability. However, under the jay is living up in the pines or palms on Monte de la Pluma I cannot see that there is a habitat for it around the Santa Rita region. The evergreen "rain" forest is very similar to that of the St gulf lowlands to the north I would judge and many of the birds of this forest - e.g. Motmotus moneta, Sittasomus griseicapillus, Ramphastos sulfuratus, Gymnostinops montezuma, Harpia harpyia (Almyer has specimen from San Pedro Muniz) and Sacoramphus papa are, I believe, birds characteristic of the humid lowland forest.
