Mobile bird identification
In winter the Ruff has dark back feathers edged with ochre on it's upperparts, giving a scaly affect. Markings are variable from bird to bird. The female is very similar to the male in winter but is slightly smaller.
Ruff Philomachus pugnax
Male Ruff in winter betray their extraordinary appearance in spring when they develop a broad feathery 'ruff' around the neck. The display and mating of the Ruff takes place at a 'lek'. Several groups of birds will gather and fight for dominance. The strongest birds managing to breed with the females.
Species: P. pugnax
Whilst the colour of the Ruff's neck feathers may vary, it's unlikely to be confused with other birds. These two male birds are challenging each other on a 'Lek'.

The female Ruff in summer lacks the neck feathers of the male. Her back shows many dark feathers edged in ochre, and her neck and breast has black speckling. When seen with the male she is visibly smaller.
