Evolution of Bird Migration: A Phylogenetic and Biogeographic Perspectiveic structure and phylogeny on the other. I will do this by proposing a number of hypotheses based on present knowledge of migration behaviour and range characteristics of migratory landbirds in general. These hypotheses will then be discussed and, in two cases, tested quantitatively using published

Recent Changes in Migratory Behaviour of Birds: A Compilation of Field Observations and Ringing Datacent observations give evidence for a high degree of flexibility in migratory behaviour (Berthold 2000). This chapter aims to survey the patterns of various recent developments and their possible causes.

This level of dependence on a single food type places intense fitness pressure on the individual to locate reliable sources for this item sufficient for survival and/or reproduction throughout the annual cycle.

Quantitative Genetic Analysis of Migratory Behaviouration was entirely determined by the environment. For instance, the activity of caged birds deprived of environmental cues during the migratory season, the migration of young birds without experience and without the guidance of their parents (e.g. cuckoos) and the departure from the breeding grounds
