The Azure-rumped Tanager is a globally threatened species restricted to a small area of only 2,500 km2 in the Pacific slope mountains of western Guatemala and Chiapas, Mexico. Researchers of the PROEVAL RAXMU Bird Monitoring Program studied the habitat use, distribution, nesting ecology, vocalizations and juvenile plumage of this tanager in Guatemala. Based on an estimated density of 33-93 birds / km2 in a study area on Atitlán volcano, and a spatial analysis of available habitat in Guatemala, the remaining population in Guatemala is estimated to be 8,250–23,250 birds. The findings support the maintenance of the IUCN Red List status of Endangered EN B1a+b(ii,iii,v), and provide a base for practical conservation measures in the coffee-dominated landscape of the Guatemalan and Chiapan Pacific slope highlands.   Details are available through several articles, of which PDF are available from the authors: knut.eisermann@proeval-raxmu.org:   Eisermann, K., S.
