[QUOTE="PaulD, post: 1750542, member: 11840"] Thanks for the comments John but I don’t think it is a case of you pays your money and you takes your choice. You look at the evidence (primarily ringing recoveries) and see what they tell you. Here’s a table of European owls showing the average distance of movement after ringing (primarily based on BWP data) [U]Ranking from most sedentary to most migratory[/U] Based on average distance moved by ringed birds (primarily based on BWP data) Tawny Owl – 15km Little Owl – 15km Ural Owl – 30km Eagle Owl – 52km Great Grey Owl – 100km Pygmy Owl - 150km Tengmalm’s Owl – irruptive movements of over 1000km noted Snowy Owl – 830km Hawk Owl – few figures, but recoveries are long distance (eg Sweden to Russia). One moved 1860km. Long-eared Owl - Migratory in parts of its range with movements of over 2000km recorded. Short-eared Owl - Migratory and nomadic. One movement of 3345km. Scops Owl – Few figures, but wholly or partially migratory and eastern birds travel 7000–8000 km to their wintering areas. That tells me that Eagle Owl is one of the more sedentary European owls and in that respect does indeed have more in common with Tawny Owl than Long-eared Owl. [/QUOTE]
