BOTERO-DELGADILLO, Esteban  and  OLACIREGUI, Christian A. Nueva información sobre la nidificación del Trepador Picofuerte (Xiphocolaptes promeropirhynchus) y el Trepador Colorado (Dendrocolaptes picumnus) a partir de observaciones en cajas nido. Hornero [online]. 2011, vol.26, n.2, pp.79-84. ISSN 0073-3407.

New information on the nesting of the strong-billed woodcreeper (Xiphocolaptes Promeropirhynchus) and the black-banded woodcreeper (Dendrocolaptes Picumnus) from observations in nest boxes. We made descriptions on the nesting of the Strong-billed Woodcreeper (Xiphocolaptes promeropirhynchus) and the Black-banded Woodcreeper (Dendrocolaptes picumnus) from observations in nest boxes at the Santa Marta Mountains, Colombia. Both species lined their cavities with dry leaves or flakes of bark, clutch sizes were of two or three eggs for Xiphocolaptes promeropirhynchus and just one egg for Dendrocolaptes picumnus, and chicks were similar to other woodcreepers' chicks. Although nest boxes could be useful for obtaining information of cavity nesters, information on natural nests is required to validate our data.
