Chosen as the bird of the year 2004 by SEO / BirdLife, the bustard – Otis dela – is one of the world's endangered species that has found one of its last refuges in Spain. The adult males of this large wading bird display long whiskers that are actually very specialized feathers used during courtship . To impress the females, the males gather in areas called leks and compete in spectacular wedding displays. The suitors bristle their whiskers until they are horizontal to the ground, at the same time that they turn the lower white parts of their body and wings upwards to look like a white ball.
