New world warblers in pine-oak forest in Mexico, Part I

A quiet highway with many serpentine curves, conifer forest, twitters of birds. The typical attributes of a high-altitude German central mountain landscape like the Black Forest in southern Germany. But the location actually is in the middle in Mexico at the slopes mountains of the central mexican plateau with peaks as high as 3,000 m above sea level (asl).  Having just crossed the 19. degree of latitude I am on the way down into the hot dry valleys at the edge of the Pacific coast. The coast is only approx. 150 km distant as the crow flies. But the difference of this forest to the dry thorn bush forests at the west coast could not be bigger. A trip on the winding mountain roads could make you feel like being in a reminiscence to the Black Forest. But here on 2,500m asl you are in the Mexican pine-oak forest. Pine- oak forest biomes are one of the dominating characteristics of mexican high altitudes, in particular on the slopes. The determining of the development of a pine-oak forest is the altitude. Slopes exposed to the coast or forests on the mountain comb are damper and more dense than the pine-oak forest s, which are oriented on one of the central dry valleys. The pine-oak forest in Mexico is very species-rich and shows a high diversity. Of the oaks alone, there are more than 170 species. But the general appearance especially of the dry pine-oak forest in Mexico is not unlike that of its european counterpart on the mountain ranges.

This is true as long until the attentive observer is caught by the charm of the birds you find here in the New world. Practically all colors are represented with its own species of bird. Consequently there are blue Mexican (Grey breasted) Jay (Aphelocoma ultramarina), red warblers (like Ergaticus ruber), brown Tufted Flycatcher (Mitrephanes phaeocercus), orange-grey Olive Warbler (Peucedramus taeniatus), yellowish- white Hermit Warbler (Dendroica occidentalis) and green Pine Flycatcher (Empidonax affinis) to observe.  The images in the gallery give you an idea of the richness of birds and colours. The winter is the favorable season for bird observation in Mexico highlands, since the food offered on the birds wintering grounds Continue reading New world warblers in pine-oak forest in Mexico, Part I
