The estimate and SE are transformed to the logit-scale using delta method, CI calculated on the logit-scale, and then the limits are back-transformed to the real (probability) scale.
Note that I'm not 100% convinced this is the best way of doing it, particularly for parts of the covariate space where different models give you quite different estimates. David Fletcher has done some work on MA CIs to try and account for these situations that I need to read up on one day.

I'll need to read David's paper as well (reading Fletcher papers is almost always a smart thing to do), but it might be useful for you to read the verbiage in the MARK book on how the CI for model-averaged estimates is handled (and how it is either the same, or different, from what Darryl describes in his reply) -- see the -sidebar- on p. 55-56 of chapter 4:
