hello im a little confused i have a pair of cockatiels and they have been together for about 2 months now and are very close so i set them up wiht a nest box but today i walked past and i saw them mating (well i dunno if they were mating but 1 was ontop of the other 1) when i walked past i scared them but i noticed that so called female was on the top and the male at the bottom!
could this be that i have gone them mixed up that the male is a female and the female a male? also could it be possible that i have 2 females or 2 males? do they usually go on top of eachother and show mating sighn( flating wings out tail in air crouching down) would 2 birds of the same sex do this as a sighn of dominence?
