Quantitative Genetic Analysis of Migratory Behaviourn was concerned with providing evidence for the existence of this migration instinct, and specifying which components of migratory behaviour are innate and which are acquired by experience or learning. These arguments were exclusively based on observational evidence. In the 1930s first experimental

Circannual and Circadian Contributions to the Timing of Avian Migrationpare the fields so that the rice can be planted in the months of the brown shrike (.), October/November, and of the Japanese sparrow hawk (.), November/December (Smythies 1960). Thus, migrants provide important cues about time of year in a region in which reliable seasonal information is scarce. In
