Thanks for this most interesting post.

I always thought it interesting when Maria says,
‘I cannot get out,’ as the starling said.” As she spoke, and it was with expression,

I thought that was a plea from Maria feeling trapped in this engagement with Mr. Rushworth when she would now rather be with Mr. Crawford.

There is a sense of foreboding I think when Mr. Crawford replies with the line Nina RG quoted. , with my assistance; I think it might be done, if you really wished to be more at large, and could allow yourself to think it not prohibited.”. I begin to sense a seducer there, though it's only a walk. He's encouraging her to do wrong, instead of courting her the right way. She's hopeful, but we know he's only trifling with her.

It's very fascinating as you've explained the locked gate standing for her innocence and Mr. Rushworth getting the key. It gives a new depth to that scene.

Does anyone else have an opinion about the starling?
Also, Barbara, I know you said you'd stop, but I would like to hear more about the symbolism you have found.
