pressures. The inventory of birds are refers to studies
in near areas. This study is a concrete contribution of
the birds of the mountain chain and north of it. We considered

(31 are endemic and 15 are quasi-endemics to Mexico)
and 73 are migratory; the remaining eleven records have
other status. Also 43 species are in endangered categories.
We include species that have not been recorded in

ranges at Nayarit. Due to the great diversity of birds observed,
it is necesary to continue the research work about
habitat use, abundance and monitoring, it will provides the
basis for the conservation of birds of Sierra de Vallejo
