I also question the use of the term "yard" within the name for the species in question. I tend to think of a "yard" as a lawn. I would think a term beter indicating their arborial nature would make sense. Maybe those of us that live in parts of the country where Sciurus carolinensis is an abundant alien should call them "Alien Invader Bushy-tailed Tree Rodents". I confess, while I sometimes appreciate Eastern Gray Squirrels as cute individuals but my concern (predictable to all who know me) is that they almost surely have been harming native species.

A review of why I consider "Alien Invader Bushy-tailed Tree Rodents" problematic for anyone who wants to read it:
I don't know just which species have declined due to the otherwise cute Eastern Grays, but you can be sure that if they eat they, they eat things that in turn have likely declined and may still be declining in the face of the successful Eastern Gray Squirrel. Birders should be reminded that they eat bird eggs and chicks. I don't know which species are preyed on the most and which may be harder to find today in areas where Sciurus carolinensis has become abundant outside of it's native range. Whatever other animals ate the same foods are likely to have declined and may still be declining in the face of the successful immigrant Eastern Gray Squirrel. If they have diseases any animal that shares that disease is likely to have declined and could still be declining do to the immigrant species. When they plant Horsechestnut seeds they displace native trees that in turn supported native communities. Every change they make in our communities of plants and animals leads to more changes through the ecosystem, leading to more changes still.

I don't think I've heard a more obnoxious term, referring to any of our beautiful squirrel species, than "urban yard rat." (This is nothing against those who use the term. They simply are repeating what they've heard.) I thought at first the reference was to us humans. That, at least, would have fit.
