Figure. Autumn migration directions (arrows) of tree pipits (Anthus trivialis), robins (Erithacus rubecula), redstarts (Phoenicurus phoenicurus), and song thrushes (Turdus philomelos) banded in southeastern Sweden (area indicated by a square) and recovered within 60 days. Directions: Tree pipit, 203.6º, mean vector length = 0.993, n = 10; robin, 220.5º, mean vector length = 0.928, n = 293; redstart, 225.9º, mean vector length = 0.975, n = 52; and song thrush, 218.8º, mean vector length = 0.947, n = 117. Recovery sites of birds banded in southeastern Sweden and reported from areas north of the banding sites in a following year are also shown as indicated in the legend (no recovery from breeding areas is available for tree pipit).
