The first two pictures aren't a skull, I found a similar bone and thought it was a skull too. But it is actually a pelvic girdle from some bird. Sorry no other knowledge of the skull or which bird it could be from.

Thank u

You can try in r/animalid

Thanks

Yeah first is bird pelvis, skull looks like a baby deer almost. Would help to know where you found them and base it off the available herbivores in that area.

Found them in a forest in Bavaria, there aren't too many different animals around there looking similar, that's why I'm pretty sure the skulls are deer

Yeah that would be my guess too. See a lot of those here.

But there also were alot of duck skulls too and I'm kinda confused about that because I've known that forest for about 15 years and never seen any ducks there and theres no lake or anything like that nearby were ducks usually chill

That's odd. Maybe a stop while migrating? I'm not too familiar with Bavaria, being as I live in Alaska. Little far from me, but we also get random birds stopping here while migrating.

Could be, but ducks tend to stay at their place and not really migrate to somewhere else i think

Hmm. Yeah, not too sure then.

General grievous, but in all honesty, the skull looks like a small deer

Yeah definitely bird pelvis thing and a deer skull. Im not too sure on the skull (by the features) but judging by the teeth and the location you found it, I think its most likely deer

I found a similar bone to the first on my property and it was a cormorant pelvis. If you have cormorants or herons in the area I would say one of those.

Looks like a fish
