I recently read Where the Crawdads Sing, by Delia Owens. It has a lot to say about how trust can overcome the seeming juxtaposition between not losing independence but maintaining a relationship. It's set in 1970's coastal North Carolina, and the author (a zoologist) uses a lot nature in the book's imagery and setting, and does it in a way that generally rings true. It's one of the better books that I've read and I'd definitely recommend it.
What's the connection between the book and today's pics? In the book the main character enjoys feeding her resident herring gulls and a couple times the author describes the young herring gulls pecking the red spot on the gony angle of the adults to induce them to cough up some fish. This morning at Tiscornia there was an adult with not one but two juvies working away at this process.
It would start with the youngsters sidling up giving begging calls with heads lowered.
This second year bird was drawing its ire a fair bit by wandering over.
