Individual longitudinal data (20 years) on goshawk ecology, demography, lifetime reproduction, territory and mate fidelity, breeding dispersal, and habitat quality by American goshawk (Astur atricapillus) [formally northern goshawk (Accipiter gentilis)] in northern Arizona, USA: 2nd edition

The American goshawk (Astur atricapillus) is listed as a sensitive species on most National Forests and has been shown to be affected by various forest management practices, especially logging and fire management. This data publication contains detailed data collected regarding lifespans, breeding lifespans, breeding attempts, number of lifetime mates, and turnover of male and female goshawks on 100+ breeding territories. Data were collected in the Kaibab Plateau in northern Arizona from 1991-2010.
These data were collected to determine the demographic performance of breeders on each territory in order to investigate the relationship between the composition and horizontal and vertical structure of forests in territories and long-term (as many as 20 years) goshawk survival and reproduction on each of 100+ territories. The overall purpose was to investigate the specific vegetation composition and 3-dimensional forest structure in territories that confers habitat quality to goshawks and the plant and animal (prey) species in their food web.

The first edition of these data (Reynolds 2019) was published on 04/23/2019. This second edition reflects updated and cross-referenced individual identifications as well as additional derived metrics of territory and individual quality. In the original dataset, a row for each year of the study (n=20) was included for each banded bird. In the second edition, years with no observations/sightings were omitted. We recommend use of this second edition.
