Die Federn des Scharlachsichlers sind durchweg charakteristisch. Die leuchtend orangerote bis rosane Färbung findet man unter Umständen in blasserer Form noch beim Rosalöffler, im Kleingefieder auch bei vielen Flamingoarten. Flamingos besitzen jedoch meist eine rötlichere und weniger orangefarbene Gefiederfärbung. Die Kiele sind zum größten Teil weiß. Die äußeren Handschwingen besitzen eine satt schwarze, definiert abgetrennte Spitze. Die Handschwingen H7-H9 sind in der Außenfahne teilweise, H10 vollständig verengt.

Im Jugendgefieder sind die Schwingen noch dunkelbraun gefärbt. Das Deckgefieder ist hell- bis mittelgrau und wechselt mit der Zeit in das leuchtende Orange des Adultkleids.

Annotations for measurement data

number of individuals n

For the statistics of the longest feather measurements, we only use data from birds having the largest feathers present. A broken, missing or growing feather, which could potentially be the longest, disqualifies the individual for measurement. Likewise, no hybrids are included in the statistics. However, birds of different ages (e.g. young and adult woodpeckers), sexes (e.g. male and female sparrowhawks) and subspecies are used equally in the diagram and can therefore lead to a very wide range of variation. The greater the number of individuals measured, the more accurate the range of variation. Very small data sets of one or only a few birds only lead to approximate results.

measurement method

The feathers are measured digitally via the scan. A ventral curvature of the feathers is straightened for the measurement, but a caudal curvature is not! Measurements are taken from the start of the calamus to the largest extension of the feather. This does not always have to be the rachis, but can also be the vanes (e.g. in the case of buntings). Special features, such as the wax platelets on the waxwing, are omitted from the measurement.

percentages

The percentages of the individual feathers, e.g. P5, indicate the proportion of individuals in which this feather is the longest of its kind. This information should always be considered in conjunction with the total number of birds measured. An indication of 100% for five individuals is no guarantee that this feather is really always the longest.
