Nature Of Migration
Currently considered non-migratory, but accounts of supposed migration, none convincing, have been published. This species may temporarily join true migrants; irruptive movements, possibly in search of food, more likely explain earlier observations of migration. One 2003 observation of nearly 500 White-tailed Hawks seen migrating near Santa Cruz, Bolivia, awaits confirmation. Further research (eg., intensive color-marking at migration points for other hawks, and/or radio-tracking) is needed to establish migration in this species.
