Thanks for the replies. The bush in question is probably a euonymus alatus compactus but I don't remember seeing it so red. I just remember the green leaves. And my goal is to have a bush that attracts birds and protects them. Not too large of a bush.
In googling I've seen that the Arrowwood Viburnum is bird friendly. Not sure if birds gather inside like with the euonymus alatus compactus.
When spring leaves appear on my sisters euonymus alatus I will add a photo.
