|Eurasian Treecreeper (Certhia familiaris) Treecreepers (Certhiidae)|
|Træløber Agateador Norteño|
2015-04-17 Vestvolden, København, Denmark
Species confirmed by voice. Short-toed Treecreeper also present at this locality. This bird looks very pure white with contrast, why I judge that it belongs to the northern subspecies, familiaris. There is a range overlap between this and macrodactyla in Denmark. Long hind claw, short bill, strong eyebrow, broken wing ladder, and pure white flanks indicate this species over Short-toed. But always best to hear the voice! The big distance between the tips of primary 7 and 6 in combination with the short distance between 7 and 8 indicate Eurasian. Also the brownish color to the primaries plus that the tips are not brightly white. However, the back edge of the steps in the yellowish wing ladder are more pointed than is normally shown by this species (acc. Svensson)

A singing bird why I assume it is a male.
I saw it in the same spot as a Short-toed Treecreeper. I don't think they interacted, but the two now being present, I think it is necessary to be aware of possible hybrids. I say this partly because some of the birds I seen in this area seem to be less obvious.
However, this bird, first of all by the song, appears to be a pure eurasian with the bright white underside, the well-marked white eyebrow, the lack of the white edge to the alula, the short bill and the primary spacing with only one broad space between tips on the folded wing.
Other marks like the color of the vane of the tail feathers seems to be less conclusive, since it appears to look different from photo to photo.
