Because of their relatively coastal habits, humpback whales were very vulnerable to whaling activities, especially after 1900, when modern techniques almost caused extinction of many populations. To allow them to recover from such an intense exploitation, it is very important to know and understand this species ecology, so that management and/or conservations measures can be implemented. Some of the most important information gathered in this context are the estimates of population size (abundance) and how animals use the surrounding environment (distribution).
