Avian Migration: Regulation of Facultative-Type Movementschanisms (Wingfield and Jacobs 1999; Jacobs and Wingfield 2000). Superimposed on the predictable life cycle are unpredictable, and potentially stressful, events that have a completely separate repertoire of physiological and behavioral traits, each with its own characteristic controls (Wingfield et

Life-History and Ecophysiological Adaptations to Migration in Australian Birdsn (for summary, see Berthold 1988), as well as food utilization (Bairlein 1985, 1991a). Intensive research on nocturnal migrants has identified these adaptations as an integral part of a precisely adjusted system.

Suraj Kumar Mallick,Somnath Rudraand autumnal migration are separate life-history stages. Given this, one would predict that the endocrine mechanisms regulating each should differ. So, too, should the development, progression, and termination of each. Attempting to test this in the field with free-living and actively moving species
