Subspecies: familiaris 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) |

Subspecies: [?] 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. |

♂. Singing made this bird easy to identify, but also the pattern of the tips of the primaries supports this species over Short-toed (which has not showed up yet in Kongelunden this year). |

♂. Was singing. The flanks look rather dirty giving impression of a Short-toed, but apart from the song, the dark-edged alula is a good field mark for Eurasian. The primary spacing, however, looks something in between the two species, which could be an intra-specific variation, or the result of mixed genes? A thought, with the dusky flank in mind too. |

Kirkelunden. Markedly different from the two short-toed, 4717-18, I also had at this spot: The proximal primary-tips clustered together, the white eyebrow, the long hindclaw and the abrupt latter pattern on the wing coverts. It also called the typicall zzhhiii call that is much more trembling than what the short-toed normally utters. |

Two birds invigorated by the shining sun, chasing each other for a while preparing for a new round in the game of constant continuation. Calling and one of them subsinging a few times. I had them in the spot where I often have Short-toed, but still no sign of that species in the forest this year. |

It didn't say anything but the pale underside, pale eyebrow, short bill, long claw and primaries with little spacing give the way. |
