Today the weather was favorable again so we decided to go back to Mohotani to circumnavigate the island, in hopes of finding the melon-headed whales and spinner dolphins and to survey for common bottlenose dolphins or other species. On the way over we observed a Kogia<\/em> spp (most likely a sima<\/em> due to dorsal fin size and shape), but it was not observed again (typical for this species) before we were able to get photo IDs or a biopsy. Once reaching Mohotani we encountered spinner dolphins, this time in a mixed aggregation with melon-headed whales, at least in the beginning. During the encounter, we observed a melon-headed whale displacing a spinner dolphin off the bow of the boat. Soon after this event the spinner dolphins departed. We counted the number of melon-headed whales to be about 300 individuals, similar to what we encountered two days ago. A good proportion of the group had distinctively marked dorsal fins some of which we recognized from the previous encounter. In addition, we were able to collect several biopsies and take underwater video. We ended the day surveying the southern coast of Hiva Oa where we encountered spotted dolphins and spinner dolphins, both close to shore.\"\"<\/a>\"\"<\/a><\/p>\n

Aujourd\u2019hui, nous avons encore b\u00e9n\u00e9fici\u00e9 d\u2019une bonne m\u00e9t\u00e9o et donc, nous avons d\u00e9cid\u00e9 de retourner \u00e0 Mohotani faire le tour de l\u2019\u00eele, dans l\u2019espoir d\u2019y retrouver les p\u00e9ponoc\u00e9phales et les dauphins \u00e0 long bec. Se rendre sur cette \u00eele nous a \u00e9galement donn\u00e9 l\u2019occasion de naviguer au large des c\u00f4tes et c\u2019est ainsi qu\u2019en chemin nous avons pu observer un cachalot nain, <\/em>Kogia sima (il aurait aussi pu s\u2019agir d\u2019un cachalot pygm\u00e9e, <\/em>K. breviceps, mais la taille et forme de l\u2019aileron dorsale tendent plut\u00f4t \u00e0 sugg\u00e9rer <\/em>K. sima). Une fois Mohotani atteint, nous sommes tomb\u00e9s sur un groupe de dauphins \u00e0 long bec, rapidement rejoint par des p\u00e9ponoc\u00e9phales qui les ont \u00e9vinc\u00e9 de l\u2019avant de notre bateau. Comme il y a deux jours, les dauphins ont \u00e9t\u00e9 trouv\u00e9s sur la c\u00f4te Est de l\u2019\u00eele et nous avons estim\u00e9 la taille du groupe \u00e0 environ 300 p\u00e9ponoc\u00e9phales. Nous avons pu observer qu\u2019un bon nombre d\u2019individus pr\u00e9sente des marques distinctives sur leur aileron, ce qui nous a notamment permis de constater que certains d\u2019entre eux \u00e9taient d\u00e9j\u00e0 pr\u00e9sents sur le site il y a deux jours. De nouvelles biopsies ont \u00e9t\u00e9 obtenues ainsi que des vid\u00e9os sous marines. Pour la fin de la journ\u00e9e, nous sommes retourn\u00e9s \u00e0 Hiva Oa o\u00f9 nous avons couvert la partie Sud de l\u2019\u00eele, rencontrant au passage des dauphins tachet\u00e9s et des dauphins \u00e0 long bec, toujours pr\u00e8s des c\u00f4tes.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
