I know that young Peach-faced lovebirds have a darker colouration under their nose on their beaks that fades as they get older. It is true that most lovebird species have no apparent differences between the sexes, not like budgies! The old pelvic bone test only works if you are experienced in it or you have another bird of the other sex to compare it to. The females have a wider spaced pelvic bone so the eggs can come out easier. The female can be slightly larger or the legs a little more widely spaced than the male because of the larger hips. Again you need another bird of the opposite sex to compare. I suggest that if you want a breeding pair to just get another one and check out their behaviour. Two males usually won’t go into the next except maybe to sleep, some will make a small attempt at nest building. Don’t expect any eggs, no eggs after a few weeks in the nest box and it it would be safe to say you have two males. Two females will be more likely to build a nest, but if they do
