Ferruginous Duck Aythya nyroca



Given that this species’s range may fluctuate considerably from year to year – particularly in Asia – owing to changing water levels, it is very hard to estimate the global population or trends. There have been rapid declines in Europe, but evidence of declines in the larger Asian populations is sparse, and sometimes contradictory, so it is currently listed as Near Threatened. Evidence of rapid declines in Asia would qualify the species for uplisting to Vulnerable.
