Yucatan Wren Campylorhynchus yucatanicus is currently listed as Near Threatened under criteria B1a+b(i,ii,iii,v); C2a(i) because, although it has an Extent of Occurrence (EOO) of less than 20,000 km2, occupied by a moderately small population (both of which are suspected to be in long-term decline owing to the increasing threat of development), its population is not considered to be severely fragmented or restricted to a few locations.
Vargas-Soriano et al. (2010) state that the species’s breeding success may be threatened by firewood collection by local people, and also express concern that human population growth and increasing land development resulting from the tourist industry in coastal areas are becoming serious threats to the species and its habitat.
Up-to-date information on the likely trends in this species’s range and population over a period of 11 years (estimate of three generations) would be welcome, as well as new information on likely threats.
