Schematic overview of the fly-ways of Ruffs (Philomachus pugnax). Red point - place on which I did my photos. The symbols signify four regions of the global breeding range. The lines summarise 364 long-distance recoveries of ruffs ringed in wintering or breeding sites, and >1000 recoveries of ruffs ringed in Western and Eastern Europe and recovered elsewhere. Solid dark grey: wintering areas. Solid light grey: the temperate and arctic breeding areas in Europe and Russia. Note that the Arctic harbours c. 95% of the global population of the ruff; numbers in the temperate breeding areas are minor and strongly declining. In black: former temperate breeding areas (source : http://www.sciencedirect.com/science/article/pii/S0006320712000729#b0420)
