Résumé :	During 1991-1997, we developed, adapted, and tested a variety of field techniques for the study of Amazona parrots in northeastern Mexico. We describe two of these techniques considered novel and employed for nest inspections and sampling crop contents of nestlings. Inspections included modification of nests and use of a video probe. Crop sampling of chicks was done using a plastic cylinder from 20 days of age until fledging. The techniques did not cause nest abandonment or increase in chick mortality. We obtained information that has substantially advanced understanding of the biology and conservation needs of these species. We hope these techniques will aid future studies and facilitate comparisons among diverse species.
