Mexiko &#; Miljoner fjärilar färgar träden brandgula
09 januari
Väster om Mexico City handlar allt om fjärilar i Monarch Butterfly Biosphere Reserve (Mariposa Monarca Biosphere Reserve), där miljontals av dem övervintra varje år. De färgar träden brandgula och fladdrar runt i luften så att himlen knappt syns. De börjar anlända i mitten av november och har tagit sig ända från USA och Kanada. Framåt mars börjar de så färden tillbaka till USA och Kanada.
Monarch Butterfly Biosphere Reserve finns med på UNESCOs lista över världsarv och fyra platser går att besöka i reservatet: El Rosario (ligger nära Ocampo), Sierra Chincua (nära Tlalpujahua and Angangueo), Cerro Pellon och Piedra Herrada.

List of birds of Mexico
This is a list of the bird species recorded in Mexico. The avifauna of Mexico included a total of species as of April , according to Bird Checklists of the World.[1] Of the species, are rare or accidental, 10 have been introduced bygd humans, are endemic, and five more breed only in Mexico though their non-breeding range is larger. Four species are known to be extinct, 68 are globally vulnerable or endangered, and three of the latter might also be extinct. The total figure includes a number of species which are known only from sight records; they are listed but not especially noted.
This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 63rd Supplement, published by the American Ornithological Society (AOS).[2] Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.
Unless otherwise noted, the species on this list are considered to occur regularly in Mexico as permanent residents, summer or winter visitors, or migrants. The follo

Birds AND Butterflies in Mexico
The migration of North America&#;s Monarch Butterflies (Danaus Plexippus Plexippus) is one of the wonders of the natural world. Unlike our feathered friends&#; migration, these butterflies somehow migrate over the course of three or four generations, with two or three generations moving north by stages from Mexico (and some other sites) to as far north as Canada, while a single generation makes the return trip. The northward-travelling butterflies live only a few weeks, but the southward-travelling and overwintering butterflies can live up to nine months. As of this writing, scientists have not determined what specific mechanisms regulate this highly irregular migration pattern.
The most important sites for wintering Monarch Butterflies are all in the Mexican state of Michoacán, where I have lived for 30 years. So it is that much worse that we, and I, had never gone to see them.
But my ornithologist friend Jonathan Vargas, who now also lives in Morelia, has been looking for interesting options for guided tours in our area. (He has already worked as a guide in the areas of San Blas and Ensenada, and has interesting projects in development fo
