   Research Interests

Northern Goshawk Breeding Ecology in aspen forests of Nevada: With the help of two graduate students, I have addressed the issue of habitat requirements of this species when nesting in an unusual setting like high- elevation aspen forests.
Swainson’s Hawk Migration: I am conducting satellite telemetry study in cooperation with several federal, state and private entities to document the routes and wintering areas of this species in while it migrates to Argentina.
Kestrel Population Ecology: I am conducting a long-term study of the longevity and lifetime reproduction of American kestrels that breed in nest boxes in an agricultural setting.

Species of Interest: 
  • White-throated Hawk
  • Turkey Vulture
  • Osprey
  • Northern Goshawk
  • Bald Eagle
  • Red-tailed Hawk
  • Swainson's Hawk
  • Ferruginous Hawk
  • Spot-winged Falconet
