A few Florida IDs

[Joe]

Is this a Northern Mockingbird?  Some of the field marks are throwing me off.

How about this one?  It doesn't appear to be a juvenile laughing gull... Ring Bill?  Again, a bit confusing.

Here it is next to some Laughing Gulls for comparison.

The Fish Crows I saw all had some blue to their eyes which is not mentioned in any of the books or sites I found.  Any ideas or experience?  They can be confused with American Crows or even Boat Tailed Grackles, but these shots are Fish Crows.

Your identification is correct.  Northern Mockingbird, Ring-billed Gull and Fish Crow.
