Is this a crow? Also how to help with their poops
Hello crow friends,
I think I have a large flock of crows in the trees right next to my apartment (they found my ornamental sweet potatoes today) I was hoping someone could confirm if this is a crow or a raven? Sorry I am having a lot of trouble differentiating.
Also I don't have any problem with the crows hanging around the house but they take very large very greasy poops on my deck. I'm assuming they are just finding food on the street and it's not doing them well.
Is there a way I can help them with this poop issue and maybe get more solid normal poops? Also save myself so stress of having to clean very difficult to get rid of grease stains everywhere up there? They also like to leave around bird parts, chicken and rib bones, and for some reason organs from small animals all over the deck. I don't think they are gifts unfortunately, but it's kinda gross, maybe someone has luck teaching them to put that stuff in the trash? Is there a YouTube or something of someone teaching them that?
I'm just trying to help organize them and keep the deck looking a little less like a bird massacre scene lol.
They do leave me white rocks sometimes which is nice though so I don't think they hate me just maybe I could be less of a toilet for them, there's like 30 of them in the tree
