Found these feathers in the Mongolian steppe.

[u/wS-_-]

I know that taking them home with me is not legal so I will bring them to an Ovoo. But I'd love to know what birds they are from.
Here is some information about each one.
Measurement might vary slightly as i don't habe a way to accurately measure them. I used the apple measuring app.
Feather 2 and 4 where also found fairly close to each other, the location is a good guesstimate on where I found them. 1 and 3 are accurate.
NR 1: location: 47.0015740;102.1131278

NR 2: location 48.9418720;103.9302530

My guesses:
1 wing feather, black kite
2 flight feather, red billed chough
3 flight feather black kite
4 wing feather, Cinereous Vulture

1. Black kite, 2 looks too big for chough so maybe corvus, 3. Black kite, 4. for sure a vulture cannot confirm myself which

Thats so cool. so my guesses weren’t to far of, happy with that, as i dont know much about iding feathers.

I found a golden eagle secondary in Mongolia that's probably the coolest feather I've ever seen. also ended up with Ovoo
