Smarter than the average bird...

[Bobbie Ireland]

Not sure whether you have Rooks Stateside... In ROC, I think we only have the Carrion Crow, tho I would stand corrected. We have a number of corvids here, and ones called Hooded Crows do exactly what you see in the short film clip... they can't get at the suet in the hanging feeder - so they take the feeder! Bird brains indeed.
