I think we're all getting on too many different lists and social networks -
responses to questions posted on one turn up on others and wind up getting
lost. The following is from Bryan W., posted to another list:
In answer to Fran, yes males of all our spring breeding amphibian species
tend to predominate among those individuals of a species arriving in the
first waves to reach a breeding pond in the spring. On heavy migration
nights early in the season, you can often plot a shift in sex ratio of
arrivals as the night progresses - nearly all males at first shifting, in
some cases, to majority females.
Sorry for the lag!
