Poblational status of the Polinar´s Wren, Cistothorus apolinari (Passeriformes: Troglodytidae) in seven wetlands of Bogota Sabanas, Colombia.

Objetive: Evaluate the state of the populations of C. apolinari in seven wetlands of the Sabana de Bogotá, searching to define what the areas evaluated mean that it hosts the largest population of the species and what other factors determine these population sizes. Methods: between July and December 2014 in seven wetlands we monitoring carried out using counting points and auditory censuses, the abundance of the Apolinar’s Wren was recorded, the vegetation cover where the individuals were recorded and the abun- dances of Shiny Cowbird Molothrus bonariensis. Results: There were 63.6 h of observation and 88 counting points, obtain a nine records of C.
