Resumen:
“Why did the warbler on my summer place in New Hampshire start his southward migration on the night of the 25th of August?” (Mayr 1961). Questions about the motivation and orientation capabilities of migratory animals have fascinated natural historians since Aristotle and Pliny the Elder. More recently, faced with the challenges of conserving migratory species (Bolger et al. 2008; Wilcove 2008), other problems have gained in importance, such as mapping migratory routes (Sawyer et al. 2009; Strandberg et al. 2009), understanding the role of individual and environmental drivers of migration patterns (Alerstam 2006; Bolger et al. 2008), or estimating the size of trans-continental migratory populations (Hahn et al. 2009). Our overall aim in this chapter is to discuss how models, combined with modern data sources and statistical methods, can be used to test different hypotheses about the causes of migration. In sections 1, 2 and 3 we structure our presentation around these three essential components (models, data, and inference) and, in section 4, we illustrate their linkages by means of several case studies.
