Caloixtla - Psilorhnius
San Fernando to La Florida
April 28 the coffee is grown. There is a place called Chicos Zapote which is 2 hours or so beyond La Florida - the vegetation is said by Rulen Diaz to be similar to that at La Florida. La Florida is located in hilly country & I saw several ridges of the type we crossed on our way from San Fernando to La Florida - beyond (=NW) of La Florida. Both Rulen Diaz and his son claimed that the brown jay was much more abundant in the lowlands NW of Chicos Zapote than in the area we traversed today - as both claimed Caloixtla was about there.
This vegetation type is occupied only by Caloixtla and the drier it is the more common it seems. Large trees are not necessary for the occurrence of this jay but then they may move about a bit and large trees probably are needed for nesting. Neither Psilorhnius nor Xanthoma occur in this vegetation type. Miranda gives a good list of species of trees of this vegetation type. It is fairly uniform in composition wherever it occurs. Apparently C. Zanatus does not occur here either as it does not occur in the Tuxtla Valley or at La Florida. I would judge that Caloixtla is one of the best "indicators" of this low deciduous forest type.
