Can I say "These are birds' eggs."?
1 If I see some buffalo horns, so can I say "These are buffalos' horns."?
2 If I see some bird eggs, so can I say "These are birds' eggs."?
3 If I see some elephant tusks, so can I say "These are elephants' tusks."?
4 If I see some bird claws, so can I say "These are birds' claws."?
5 Or I only use "buffalos' horns, birds' eggs, elephants' tusks, birds' claws" when I say about them in general and there is no picture of them?
I like birds' eggs.
Buffalos' horns are very dangerous.
Elephants' tusks are pointed.
Birds' claws are sharp.
Thank you for your help!
