      The Bar-tailed godwit L. lapponica is smaller than the Black-tailed, and not only shorter-legged and shorter-billed than the Bar-tailed, but also (obviously) different from it Abstract. Ethology arose as a discipline within zoology, with distinctly different aims and methods from psychology (Tinbergen, ). From its inception, ethology embraced phylogenesis, inheritance, “survival value,” and adaptation—research areas that relied on comparative observations and inductive reasoning (Darwin, , ).

As such, it remains unclear how likely migration is to affect the population dynamics of migratory species and how capable migrants may be of responding to changing This is higher than all previously published estimates for black‐tailed godwits: 45% (Hegyi and Sasvari ), 41% (Schekkerman and Müskens ), 40% (van Balen ), 29% (Buker and Winkelman ) and 20% (Senner et al.
