Conspicuous colouration in Capreolus

There is a white patch on the hindquarters of Capreolus, in winter pelage.

This constitutes a flag if unexpanded (https://www.inaturalist.org/observations/200496200).

The same feature constitutes a bleeze if expanded.

This is a difference of scale, effected by complex piloerection.

This piloerection occurs sometimes when the figure is stationary, and sometimes when the figure is fleeing.

Then feature in question can be called ischioperineal, because it is located on the buttocks and the perineum, which connects the left and right buttocks.
