model check for negative binomial model

Short answer: if emergence success gets much above 50%, then the
approximation you're making (Poisson + offset for binomial, or NB +
offset for negative binomial) doesn't work well.  You might try a
beta-binomial (with glmmTMB) or a binomial + an observation-level random
effect.

  (On the other hand, your intercept is -0.3, which corresponds to a
baseline emergence of 0.42 - not *very* high (but some beaches and years
will be well above that ...)

  Beyond that, are there any obvious patterns of mis-fit in the
predicted values ... ?
