Hey FR
Well that would be ideal, if there was a place that had adults to compare and learn from. The thing is, most of the locations around here, don't have or know the sex of their monitors. Individual pics don't really help me due to my inexperiance. If I had one to compare it to of equal size, then maybe I would be able to tell. From the pic you posted, it's easy to tell. But I don't have anything to compare it to, as far as eyes, head, build, etc. Mine seems to have a shorter head structure as compared to your pic of the male. I'll do my best. Thanks..
