Sandhill crane question

I think it might be either a juvenile or an immature.

This is an adult bird. There are very few if any juvenile birds of any species this time of year- most, including Sandhill Crane, will have at least molted once. The reasoning behind the rust staining is just that- staining. Sandhill Cranes often get dirt and soil on their plumage, hence the reddish coloration.

This is an adult bird. Sniped by @Hasan

"Plumage becomes stained adventitiously for camouflage through application of soil to plumage or an oxidation process (Taverner 1929, Drewien 1973, Nesbitt 1975a, Pyle 2008); results in plumage ranging from drab-clay to cinnamon-rufous (ferric oxide). Stained feathers occur below mid-neck and are particularly apparent among upperwing primary and secondary coverts and upper breast feathers." - BOW

Thanks for the replies. So it seems this is a something the bird does to itself. I wonder if the stain is permanent once it occurs.

Since they molt, no. They would have to stain new feathers again.
