White-faced Whistling Duck / Dendrocygna viduata

"The white-faced whistling duck (Dendrocygna viduata) is a whistling duck that breeds in sub-Saharan Africa and much of South America.

This species is gregarious, and at favoured sites, the flocks of a thousand or more birds arriving at dawn are an impressive sight. As the name implies, these are noisy birds with a clear three-note whistling call.

This is an abundant species. It is largely resident, apart from local movements which can be 100 km or more." From Wikipedia.

"With a very wide distribution, and a large population that is thought to be increasing in size, the white-faced whistling-duck is not under immediate threat of extinction. The species is, however, susceptible to avian botulism and avian influenza, and so may become threatened by future outbreaks of these diseases. In parts of its African range, the white-faced whistling-duck is hunted for local consumption and trade, such as in Malawi and Botswana, and is hunted for use in traditional medicine in Nigeria " From Arkive.org.

This photo was taken on 29 September 2015, at the Calgary Zoo. That day, my alarm clock was set for 6:30 am so that I could go on a birding walk with friends. Unfortunately, I didn't read the e-mail carefully enough, so hadn't seen that the meeting place was not where I thought. Of course, no one else showed up where I was, so I took myself off to the Calgary Zoo instead. I had planned on going there after the walk, anyway.
