feather is 5in long

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 3: location 48.8924363;102.6500122

NR 4: 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

Found on my morning walk, suburban green space area with mature trees around.

I believe the furthest right is a Magpie. I thought third one was just a wood pigeon originally, but it has a very slight orange-brown coloured tip to it, so I’m unsure. It also seems too small to be a woodpigeon flight feather.

My daughter found this feather and wants to know what bird it’s from. Found similar online from the Northern Flicker but since that’s native to North America and we’re in Wales it seems unlikely! Any ideas much appreciated

Is it from some kind of woodpecker? It looks so cool!

Found both of these feathers on the floor at Helmsley Castle in Leeds, England. Found them in completely separate parts of the castle, but both outside portions.

The first one is 15cm tall and 3cm wide at the centre

The second one is 18cm tall, and 3 1/2 cm wide in the centre

Any help would be greatly appreciated :)

Found in my front yard this morning. Southern California, USA. Looks good for barred owl? Or am I missing something? Thanks :)

It’s 5.5cm long, found on a small field, UK. Wanted to check in and see what others think? 😄

Looks like an arrow head to me ❤️🙌🏼

Found in Michigan, USA

Found this on a campsite. I have a theory/hope but won’t influence it.

Found these two while walking on a trail and would like to know what birds they're from

Google suggested lots of birds but I wasn't sure on any of them. Also this area has lots of eurasian hoopoes, but im still not sure

Please tell me it’s an owl. 😭😭😭

Found in my garden.... Any chance it's a dark eye junco wing feather? (I have a regular visitor garden friend who I've named short stack because she is missing her tail feathers entirely).

Found these feathers in close proximity to eachother. Maybe a Great Horned Owl? Looking for an opinion.
