Blackcap
Sylvia atricapilla
species of Sylviidae

2nd cy male
ad. female

Die Mönchsgrasmücke besitzt einen Geschlechtsdimorphismus, welcher sich vorallem im Kleingefieder am Kopf zeigt. Die Handschwingen sind grau mit nur einem sehr geringen Brauntanteil. Die Außenfahnen sind leicht olivgrün gefärbt. Die Innenfahne besitzt einen hellgrauen Kontursaum. Die Armschwingen sind ebenso gefärbt. Die Schirmfedern sind ganzheitlich grau gefärbt mit einem sehr leichten Olivton. Die Steuerfedern sind mittelgrau gefärbt ohne jegliche Grünfärbung. Die Innenfahne besitzt eine leichte, helle Innenfahnenkontur.

Die OSd sind wie die Schirmfedern grau gefärbt, etwas heller als die Steuerfedern. Die USd sind fast reinweiß, mit einem dunkelgrauen Zentrum.

detailed information

The wing length is measured on the flattened and straightened wing ("maximum chord") from the carpal joint to the tip of the longest primary feather, the so-called "Kleinschmidt-method".

combined data from:
Avonet1: 73 - 80mm n=21

The hand-wing-index, introduced by Kipp 1959, is calculated as the ratio of the hand length (difference between the length of the longest primary and the first secondary) to the wing length.

combined data from:
Avonet1: 25 - 29% n=20,
The primaries-index is calculated as the ratio of the longest primary feather length to the first (outermost) secondary. It is the equivalent of the hand-wing index for feather measurements. The wing length/longest primary ratio is calculated as the ratio of the wing length to the length of the longest primary feather. The hand-wing-index/primaries-index ratio is calculated as the ratio of the hand-wing index to the primaries-index.
