Jonathan Felis
Jonathan Felis is a geographer at the Western Ecological Research Center.
The research Jonathan Felis is involved in seeks to understand seabird foraging ecology and identify the processes responsible for habitat selection, particularly through the use of tracking technologies and at-sea surveys. As a geographer, Jonathan's goal is to apply these data spatially in order to better inform conservation and management decisions in the context of marine spatial planning.

USGS wildlife biologist Emma Kelsey searches for potential Ashy storm-petrel nesting habitat on Piedras Blancas rock, off the California coast. Ashy storm-petrels make their home in burrows and crevices on offshore rocks and islands, and only enter and leave nests under the cover of darkness.

The red-footed booby is a seabird that ranges across tropical oceans of the world, including Hawaiʻi. And yes, these boobies do have startlingly bright red feet set off by their awesome blue bills. This bird is nesting at Kīlauea Point National Wildlife Refuge, an important seabird breeding site on Kauaʻi.

A breeding colony of California common murres (Uria aalge californica) on Prince Island off San Miguel Island off Southern California. Ecologists Josh Adams and Jonathan Felis of the USGS Western Ecological Research Center shot this and other high-resolution digital telephotos from a research vessel, and used the photos to identify nesting and feeding behavior.
