Abstract: Objectives To document Red-tailed Hawk migration and dispersal from summer breeding territories in GTNP, and to investigate if events that occur during the winter portion of the annual lifecycle might contribute to the low reproductive rate observed in this population. Findings and Status Nine adult Red-tailed Hawks have been instrumented with PTT satellite transmitters. Six have migrated into Mexico, two migrated to the northern portion of Latin America, and one wintered in southern New Mexico. We are documenting flight paths, stop over sites, and winter territories. These data have not been analyzed to date. We have initiated a cooperative research program with biologists from Mexico, with the goal of establishing long-term environmental assessment efforts within and adjacent to Red-tailed Hawk winter territories.

| ABSTRACT | Objectives
To document Red-tailed Hawk migration and dispersal from summer breeding territories in GTNP, and to investigate if events that occur during the winter portion of the annual lifecycle might contribute to the low reproductive rate observed in this population.
Findings and Status
Nine adult Red-tailed Hawks have been instrumented with PTT satellite transmitters. Six have migrated into Mexico, two migrated to the northern portion of Latin America, and one wintered in southern New Mexico. We are documenting flight paths, stop over sites, and winter territories. These data have not been analyzed to date. We have initiated a cooperative research program with biologists from Mexico, with the goal of establishing long-term environmental assessment efforts within and adjacent to Red-tailed Hawk winter territories. |
