This investigation was partially supported by INVEMAR, the association CALIDRIS, COLCIENCIAS (Project 2105-09-13527-03), the Department of Animal Ecology and Special Zoology, Justus-Liebig-University Giessen, Germany (JLU), the German Academic Exchange Service (DAAD), the Malpelo Foundation (in special S. Bessudo, G. Soler and Y. Lefèvre), the Colombian Ministry of Environment, Housing and Territorial Development, the Special Administrative Unit for the System of National Natural Parks of Colombia, the National Navy of Colombia (especially, the marine corps in Malpelo) and the Training Course SUCOMAR 2005, offered by InWent. This study was supported in the field by the Colombian Navy ships ARC Malpelo, ARC Valle del Cauca and ARC Caldas, as well as by the ship María Patricia (especially H. Botero) and the ship Anita. Special gratitude to the advisory and support to the project provided by B. Werding and V. Wolters (JLU), D. Anderson, S. García and F. Estela. We are grateful to M. Rodríguez, P. Herrón, J. C. Botello and J. Zamudio for assistance in the field. The aerial photographs were provided through R. Pitman and F. Zapata by the Photogrammetry Group of NOAA, Southwest Fisheries Science Center, La Jolla, California. The satellite image was provided by the program ASTER of the NASA. T. Gottschalk and A. Misok (JLU), B. Posada, P. Lozano and C. Segura (INVEMAR) provided useful comments and technical support during the analysis of the information. We thank A. Franco and two anonymous reviewers for contributing with the improvement of the manuscript. M. Mendoza and A. Hiller kindly helped to write the English version of this paper.

N2 - The spatial distribution of seabird nests present on Malpelo Island, the main characteristics of the Island's topography, and the types of substratum available for nesting were addressed using a Digital Elevation Model (DEM). The model is based on data from remote sensors (satellite images, aerial photography and panoramic photography), and from field data processed through a geographical information system. The nests of Sula granti prevail on the surfaces of Malpelo Island and neighboring islets, while those of the remaining species (S. sula, Creagrus furcatus, Anous stolidus, A. minutus and Gygis alba) are spatially restricted to the cliff margins and to crevices or caverns at different heights. The presence of terrestrial predators and predatory birds (Fregata spp.) seems to mainly explain the marginal distribution of other breeding species. The cartographic data presented here differ significantly from past and current representations, especially those concerning the island's emerged surface and other geomorphologic features. This new cartographical information will support future studies on the terrestrial fauna and flora of Malpelo Island and its islets.
