A lost corvid on the roof

I thought it was a crow, but this one was different – somewhat bigger than a crow and smaller than a raven.

• It has that hair tuft (feathers) under the neck but not fully developed like the raven

• It was walking alone around (the outside of) our house and seemed lost – unlike crows who always seem to come in pairs and dive in at one spot

I wonder if it is a juvenile raven.
