Fig. 12.1 Southern hemisphere humpback whale male singing near Isla del Caño, Costa Rica in
2016. The island, reefs, and humpback whales attract hundreds of tourists to the island each year.
Tour operators in Uvita, Drake bay and Sierpe (and likely other locations along the coast) offer
tours to the island on daily basis. In this figure we show an example of the noise emitted by a passing boat and its overlap in frequency with some elements of the whale song. These recordings were
made using underwater recorders (uRUDAR-mk2 from Cetacean Research Technology) during a
pilot project funded by Conservation International Costa Rica (a) Boat passing by masking elements of singing humpback whale. (b) Humpback whale signing in the absence of engine noise
