We analysed the avifauna of the Ramsar site ‘Río San Pedro-Meoqui’ (RSPM) according to avifaunal richness, taxonomic distinctness and conservation. We recorded a total of 199 species constituting 41.11% of the species recorded from Chihuahua and 17.30% of the Mexican avifauna. Avifauna belongs to 137 genera and 49 families, where the most species-rich families were Anatidae (23 species) and Emberizidae (14 species). Taxonomic distinctness of the RSPM was compared with five other Ramsar sites and was above the funnel plot with a high average taxonomic distinctness (Δ⁺ = 90.13). The pair of Ramsar sites with highest dissimilarity were Laguna San Juan de los Ahorcados (68 species) and Manantiales Geotermales de Julimes (81 species) with 48.52% dissimilarity. The data presented herein indicates that a reassessment of the ornithological value of northern Mexican wetlands is needed given that some areas are ‘hotspots’ for the region’s bird species pool (the Chihuahuan Desert), under a taxonomic and phylogenetic perspective.
