Abstract	Ross’s Gull is one of the most emblematic Arctic birds and least known seabirds in the world; post-breeding movements and the use of sea-ice habitats have been long debated, but described only from scattered observations. We tracked two adults, a male and female, breeding in the Kolyma Delta, Russia, using the lightest (<5 g) satellite transmitters currently available: the transmitters provided data for 44 and 132 days for the female and male, respectively. After departing from the breeding area and reaching the nearby Laptev Sea at the beginning of July, both birds moved NW, and the male staged until the end of September in an area of scattered sea-ice (concentration 50–100 %), NE of Severnaya Zemlya archipelago, between 80 and 85° N. By mid-October, most likely escaping the polar night, this bird reached the coast of NW Alaska, and a few days later it arrived in the coastal wetlands of North Chukotka, where it remained until the transmitter stopped in early November.Die Rosenmöwe gehört zu den emblematischsten Vögeln der Arktis, doch ist ihre Biologie und Ökologie kaum bekannt. Die bisherigen Erkenntnisse über ihre postnuptialen Wanderungen und die Nutzung von Packeis stützten sich auf lediglich einzelne Beobachtungen. Mit Hilfe der kleinsten derzeit verfügbaren Satelliten-Sender (<5 g) gelang es uns, ein Männchen und ein Weibchen, die beide im russischen Kolyma-Delta brüteten, während 132 und 44 Tagen zu verfolgen. Vom Brutgebiet aus gelangten sie Anfang Juli zunächst in die benachbarte Laptewsee. Anschließend flogen beide in Richtung Nordwesten an den Rand des Packeises. Das Männchen blieb bis Ende September zwischen 80 und 85° nördlicher Breite nordöstlich der Inselgruppe von Sewernaja Semlja, in einem Gebiet mit einer Eiskonzentration von 50–100 %. Mitte Oktober zog dieser Vogel an die Nordwestküste von Alaska, wohl um der Polarnacht zu entfliehen. Wenige Tage später erreichte er die küstennahen Feuchtgebiete im Norden Tschukotkas, wo er bis Anfang November, als der Sender ausfiel, blieb.
