Seagulls are just beach pigeons and have limited grace, style, and cleverness, while on the other hand, corvids are sleek, fast, have phenomenal visual acuity, are super intelligent, and have other attributes that place them well above other birds. And a Crow (and its cousin, the Raven), will interact with humans quite nicely, although if you make an enemy of one, for whatever reason, be prepared to deal with the consequences. For a long time...
And then there are the supernatural components to a corvid, but that's a topic for another post...
