The study of the birds of the BPRG began in September, 1997 and concluded in September, 1999, in intermittent periods. Nearly 400 diurnal hours were dedicated to the observation. Four mist-nets were strategically located, completing a total of approximately 130 diurnal hours. Recordings were obtained with the help of Francisco Sornoza. Also, data was obtained of specimens deposited in the collections of the Museo Ecuatoriano de Ciencias Naturales (MECN) and of the Western Foundation of Vertebrate Zoology (WFVZ). The taxonomy and sequence of species utilized follows Ridgely et al. 1998.

We thank the ornithologist Francisco Sornoza-Molina for the constant support before and during the work of writing the manuscript. Also we are thankful with Dr. Manuel Marin of the Western Foundation of Vertebrate Zoology for sending us the data of his investigations and the information of the collected specimens in the BPRG (deposited in WFVZ). We thank Marco Jácome of the Museo Ecuatoriano de Ciencias Naturales (MECN) that permits us to consult birds collection that he is in charge of. Juan Fernando Freire and Jaime Chávez of the Museo de Vertebrados, Pontificia Universidad Católica del Ecuador, helped us with data and observations. For providing the literature, we recognize Niels Krabbe, Roberto Phillips, Manuel Marin and Mark Robbins. We also appreciate Paul Greenfield, Niels Krabbe and Juan Fernando Freire for the commentaries and opinions realized upon revising the draft of the manuscript, and to Mark A. Podvin and Gabriela Teran, professor and student of the Universidad San Francisco de Quito for helping in the translation of the article. Universidad San Francisco de Quito, the Ornithological Foundation of Ecuador, CECIA and, the Regional Office of Americas of BirdLife International gave free entrance to the libraries and permits in over an occasion the use of their installations. Universidad San Francisco de Quito permits us the entrance to the Herbarium (QUSF) of the Environmental Science School that helped us in the identification of the samples. For the faithful field assistance and contribution of data we recognize the invaluable help from: Javier Robayo, Katiusca Valarezo, Margarita Brandt, Angel Chiriboga, Darryl Hutchinson, David Romo, Monica Swartz, Nelson Zabala, Silvia Recalde and Geovanna Robayo (all of them from or closely related to the Universidad San Francisco de Quito). This paper could not have been written without the initiative and support of Zeni Alpuerto, Roberto Phillips, Allan Phillips A., Laura Heredia and María Elena Heredia: Thank you Friends.
