dead bird's.

hi guy's .. before i start i apologise if i offend anyone. but with the bad weather we are having. some bird's are not going to make it and succumb to the weather . i would like to ask if any member's see such bird's. to let me know, i'am a taxidermist and  hate the thought of bird's just rotting, strange as it maybe . i will say as i said before. i would be more than happy to donate specimen's  back, to rspb saltholme, teesmouth bird club. for educational purposes, nature talk's ect. i attach a couple of pics of bird's i prepared recently.  best.   lee...

All examples of the Grocer's apostrophe. I am sure this is the only offence you will cause anybody.
[No apostrophe needed in these words as they are plurals].
