Hi there I've recently acquired 2 pink bourkes 1 does look bigger than the other but is there any other way to know if they're a breeding pair ? Before i dna them . Thanks
How old are they? With the young ones it's impossible to sex them.
In my case the male is bigger too but I'm not sure if all males are bigger - in your case both look like males but I had a situation when my "male" started getting more and more grey feathers and started behaving like a female.... because "he" was a female (that's why I wrote that age matters - because they can change plumage)
