Black-headed Gull - Pink coloration

Below is an overview of individuals showing a pink hue on the body and wing feathers.

This is reportedly due to the secretion from the preen gland, with which the feathers are maintained. This effect is supposedly diet-related.

Leucistic adult Black-headed Gull: some of the scapulars, tertial #3 (on both sides) and greater covert #2 (on the right-hand side) are white. This individual also showed a pink colouration on the breast and on the shaft of the outer three primaries.

The pink coloration apparently does not interfere with finding a partner (inset).
