| Subject: | Budgerigar cere colour and gender |

It is rather a generalisation to assume that all budgerigars with a
blue cere are males. Females in non-breeding condition may develop a
fully blue cere and, less frequently, males out of breeding condition
may develop a brown cere. I think that the bird with broad pale
covert fringes is a male but the other bird looks more like a female
except for the blue cere. Behaviour and structure are useful
indicators of gender also.
