DescriptionLittle is known about shortâfinned pilot whales (Globicephala macrorhynchus) in the western North Pacific outside of Japanese coastal waters. To expand understanding of shortâfinned pilot whale ecology in the region, we conducted smallâboat surveys in 2010â2016 within the Mariana Archipelago to investigate individual associations, movements, spatial use, and dive behavior of shortâfinned pilot whales. We collected genetic, photoâidentification, and satelliteâtag data and identified 191 distinctive individuals. A preliminary social network diagram of photoâcataloged individuals revealed a main cluster that comprised 82% of individuals, representing all five mitochondrial DNA haplotypes identified within the population. Kernel density estimates for tagged shortâfinned pilot whales (n = 11) during summer were used to identify areas with the highest probability of use (10% probability density contour), core area (50%) and home range (95%). The area with highest probability of use by shortâfinned pilot whales was off the northwest side of Guam. Satellite tag data also suggest that some individuals are islandâassociated yearâround. Data from five locationâdive tags demonstrated that the shortâfinned pilot whales dove more often to intermediate depths at twilight and night, suggesting they may target prey that forage on the deep scattering layer as it migrates to and from the surface.

Little is known about shortâfinned pilot whales (Globicephala macrorhynchus) in the western North Pacific outside of Japanese coastal waters. To expand understanding of shortâfinned pilot whale ecology in the region, we conducted smallâboat surveys in 2010â2016 within the Mariana Archipelago to investigate individual associations, movements, spatial use, and dive behavior of shortâfinned pilot whales. We collected genetic, photoâidentification, and satelliteâtag data and identified 191 distinctive individuals. A preliminary social network diagram of photoâcataloged individuals revealed a main cluster that comprised 82% of individuals, representing all five mitochondrial DNA haplotypes identified within the population. Kernel density estimates for tagged shortâfinned pilot whales (n = 11) during summer were used to identify areas with the highest probability of use (10% probability density contour), core area (50%) and home range (95%). The area with highest probability of use by shortâfinned pilot whales was off the northwest side of Guam. Satellite tag data also suggest that some individuals are islandâassociated yearâround. Data from five locationâdive tags demonstrated that the shortâfinned pilot whales dove more often to intermediate depths at twilight and night, suggesting they may target prey that forage on the deep scattering layer as it migrates to and from the surface. |
