Northern bald ibis' shimmering feathers

This species (also known as the Waldrapp ibis) has undergone a long-term decline and now has an extremely small population, with over 95% of truly wild birds concentrated in one subpopulation in Morocco. Numbers are currently increasing owing to management actions and consequent improved breeding success. However, this improvement in its status in Morocco is very recent and has not yet led to an increase in the number of colonies. In Syria its population appears to have declined dramatically in the past 30 years. The species is still critically endangered for these reasons.

IDENTIFICATION
70-80 cm. They are essentially black but with iridescent tints of blue, green and copper in sunlight. Frankly you would struggle to mistake this bird for anything else, except a feather duster perhaps.
