iron the culprate in pintail
- Hi Yakkers,
I found a paper published in Wilson Bulletin in 1909 talking about the
rusty stain in the feathers of wild ducks, and it was also found in
pintails. All observations were in spring and when the birds forage in
iron rich waters, the water dries on the feathers, the hydrogen is lost,
and it forms the oxide or iron rust.
Sure makes the ducks look cool though!
