Answer:
A- Add details about how to set up the yards
Step-by-step explanation:
Option B is simply unhelpful. To help a bird, you do nothing by watching it. Oh look at this bird getting hurt, let me WATCH THIS, WHERE DID I LEAVE MY POPCORN?! See, not that helpful.

Option D... what. is. this. The residents don't matter! of course, maybe to the birds and the residents should be informed, but ever so much LESS SO.
Sorry if my passion-filled writing is a bit much.
