Help! Does anyone know what kind of eggs are these?

Making some reseach in wild birds parasites I found these eggs in feces samples.

Birds hosts:

A - Asio otus [ long-eared owl ]

B - Athene noctua [ little owl ]

C - Aquila pennata [ booted eagle ]

D - Milvus migrans [ black kite ]

E - Buteo buteo [ common buzzard ]

F - Athene noctua [little owl ]

I thinks they're all the same kind of egg, they're very similar in morphology and size.

Thank you, in advance, for your kind help!

Thank you for all your answers! When I did the research I didn't make any measures, so it's difficult to add a reference scale. All I can say is that they're all almost the same size and the magnification is:

Picture 1, 4, 6, 7, 9: x400

Picture 2, 5: x200

Picture 3, 8, 10: x100
