Territorial fidelity of willow warbler (Phylloscopus trochilus
) males and success in competition over territories.
Taxa with large ranges in northern Asia appear to have spread largely from the west ([ILLUSTRATION FOR FIGURE 1 OMITTED]; collybita group, trochilus
, sibilatrix) and from the east (e.g., borealis, inornatus, schwarzii).
In a study of Willow Warblers, Phylloscopus trochilus
, 13% of copulations were EPCs, but none of 120 offspring were determined to have resulted from EPFs using DNA fingerprints (Gyllensten et al.
affinis, griseolus, tytleri, trochilus
, some subspecies of collybita).
