My usual problem crossword

[beanpole]

First of all a happy new year to all those who contribute to Answerbank. people like me would be lost and in despair without you.

2 m issing clues in this request

11across One follows a sick looking, tailless ,round bird (5) G---E

2 possible answers come to mind Grebe oGeese

2d Right to opt out of concern fills one with optimimism (5) E?A?E

Elate looks probable.

if so third letter of 5a is e which is why I am thinking Grebe/Goose for 5a but have no idea why

Help appreciated

[dr b]

Right out of RELATE leaves ELATE.

Don't see the other one just yet.

11a one follows A = B, sick looking = green, tailless = gree round b...grebe

many thanks to both of you. The explanation to 11a is brilliant and certainly beyond my reasoning.

Even after New Year you are certainly on the ball.
