英文摘要	The Chilean Woodstar (Eulidia yarrellii) is a critically endangered hummingbird of the Atacama desert in northern Chile, with a population estimate of around 320 individuals in 2017. To generate useful information for the design of population-recovery actions, we conducted a study of the nesting ecology of the species between 2006 and 2008. Our specific goals were to provide a quantitative description of the species breeding habitat, to describe the basic breeding biology of the species, and to assess the current levels of nesting success. Most of our work was conducted in the valleys of Azapa and Vitor, two of the three last valleys where the species is known to persist. Although we recorded some juveniles in Azapa, we only observed the species nesting in one site in Chaca (Vitor valley), in a small (1.4 ha) olive grove where 13-20 simultaneous nests were found during the studied breeding seasons. Nesting occurs in September-October, and its timing is apparently synchronized with the flowering of chanar (Geoffroea decorticans). The species has a particularly long breeding period with an average of 48 days (17 d for the egg stage, 31 d for the nestling stage). The Mayfield index of nest success ranged from 21-44%. The probability of nest failure was significantly higher closer to the feeding areas. The implications of our results for a habitat restoration program are discussed, particularly the different requirements of females and males.
