Cetacean diurnal behavior in the Guanacaste Conservation Area, Costa Rica
Introduction: Three species of cetaceans, the pantropical spotted dolphin (Stenella attenuata attenuata), the bottlenose dolphin (Tursiops truncatus) and the humpback whale (Megaptera novaeangliae), are important components of the marine fauna of the Guanacaste Conservation Area (ACG). However, basi...

The behavior scanning method was used to identify the general behavior of the cetacean groups. Results: Encounters were recorded for the three species, in a total of 36 sightings, but only for S. attenuata and M. novaeangliae for considerable periods of time. Stenella attenuata exhibited a wide variety of behaviors, being foraging (X2 = 29.42; d.f. = 1; P < 0.001) and travelling (X2 = 38.33; d.f. = 1; P < 0.001) significantly higher during the rainy season. Predominant behaviors for the humpback whale were mother-calf association, social and travelling; being the latter higher during the rainy season (X2 = 78.16; d.f. = 1; P < 0.001). Conclusions: Behaviors such as foraging and mother-calf were the most representative among species and the most frequent. This suggests that the area can be considered as a critical habitat for these species of cetaceans, with particular importance for highly migratory species such as humpback whales.
