Priorities for Future Research

Introduction

A recommendation for quantified studies of aspects of the ecology and breeding biology of Black Falcon at higher degree level (especially in South Australia, New South Wales, or Queensland) (120), was partly fulfilled by later studies, including by a postgraduate student (9, 10, 19). Identified priorities and other avenues for further research (5, 19, 3) include:

  • studies of home range and habitat use by radio and/or satellite telemetry;
  • greater banding effort;
  • long-term monitoring of territory occupancy and breeding success at sample locations;
  • identification of regular nonbreeding areas or territories;
  • comparative aerodynamics of the Black Falcon and the Peregrine Falcon (Falco peregrinus);
  • a more complete time-budget study of an entire, successful breeding cycle.

Other gaps in knowledge of the Black Falcon include:

  • egg-laying intervals;
  • sex ratios at hatching, fledging, and in free-flying falcons;
  • breeding productivity in relation to prey abundance;
  • hunting success;
  • dispersal routes and destinations of juveniles, and movements of other age classes;
  • age-related mortality, survivorship, and associated factors;
  • age-related changes in plumage and bare-part colors, and age at first breeding;
  • lifetime reproductive success;
  • factors limiting or regulating the falcon's population;
  • population impact of agricultural chemicals (e.g., poison baits, especially second-generation anticoagulant rodenticides, and insecticides used on locust plagues);
  • biology of pre-breeding and non-breeding individuals (e.g., floaters); and
  • ecological studies (including satellite-tracking to determine dispersal and migration) in regions where the species is unstudied (e.g., South Australia and inland Queensland).
