Migratory round-trip of individually identified humpback whales at the Strait of Magellan: clues on transit times and phylopatry to destinations Ciclo migratorio de ballenas jorobadas individualizadas del estrecho de Magallanes: indicios sobre la duración de la migración y filopatría en los destinos
Humpback whales undertake seasonal migration between productive high-latitude areas where they feed in summer and low-latitude tropical waters where mating and calving occur during winter. In the eastern south Pacific, the species breeds off Colombia and Ecuador, and feeds primarily in the western A...
