Satellite tracking of Ross’s Gull Rhodostethia rosea in the Arctic Ocean

Hidden in the darkness of the Polar night: a first glimpse into winter migration of the Svalbard rock ptarmigan

“…Anecdotic observations describe high altitude, directional flights of ptarmigan in autumn resembling what normally characterise long-range migration flights (Løvenskiold 1964). The use of satellite telemetry is a useful technique to document migratory behaviour of arctic birds (Gilg et al 2010(Gilg et al , 2016. The high-Arctic Svalbard is a remote archipelago (62 700 km 2 ) with few human inhabitants (approximately 2700 people) on a quite restricted area (three small local settlements) so the ability to mark and recapture birds at many different locations is limited.…”
