Blue Cere
Beatrix Gerke
If the cere is a bright/deep true blue, then you have a male, and it is probably older than 6 months. It can take up to a year for the cere color to change, but a bright/deep true blue indicates a mature male. If the cere is a pale lavender then it could be male or female. Cere color is not an indication of gender in all of the color mutations of parakeets. In the pastels and solid color color mutations, the cere will be a pinkish lavender, and will remain that color regardless of the age or gender. With these colors, it is wise to have the DNA testing done. The standard blue and standard grey budgies will have the true blue cere for a male, and white to brown for a female. But there are pastel and solids of these colors, and these would require a DNA test to be sure of the gender.
For the best results with breeding, wait until the birds are 2 years old, only have one pair per cage, never allow related birds to breed and rest your pairs for 6 months in between each clutch. And of course feed a quality diet of pellets, greens, veggies and during breeding, an egg food. Each pair should also have a cuttlebone and/or mineral block. A foraging pellet such as Nutri-Berries or Avi-Cakes can be fed instead of pellets, and will provide some fresh, whole seeds while still being nutritionally balanced.
Male birds, although nearly always rocking a blue cere, may have a brown or browny-pink cere if his breeding hormones dip below the norm, or if he is ill. An ill male may also develop a yellow-greenish tinge around the nostril area. In an immature cock, the cere is a blueish pink or light purple.
Younger birds of all types are much harder to sex than adults. At around three weeks old, cocks develop a blueish-pink cere, sometimes verging on lilac, and females have a blueish-white one, usually with a hint of pink around the nostrils. If the young birds belong to the Albino and Lutino group, you will not be able to sex them without an internal examination - which is something you should never attempt in any circumstances. Time will deliver the answer, and there is no need to interfere with a still-developing bird.
I got a budgie and named it ari so it would be a gender neutral name but idk if it's a girl or boy I can't find anything to tell what gender a rainbow budgie/parakeet is his cere is pink white and baby blue
My mother and I were just having a conversation about the birds my brother and I kept as children. They were "male" but turned out to be female when they both starting laying eggs simultaneously. The cere was always a distinct blue on both birds. I sincerely hope it meant that they were young females and not ill adult females, however they did die after only a few years of having them. I imagine it had something to do with excessive egg laying, we tried to supplement nutrients to make up for it. My mother's cockatiel had the exact same problem and laid eggs constantly until she prolapsed and had to be put down. If I could turn back time I would've done more for these birds but be we were young and the pet store indicated that all of our birds were male! We had no idea what we were dealing with. Misinformation abounds in many pet stores, do your research!
We have a rainbow budgie called Eli . having doubts if its a boy.. The cere has gone very brownbut only after a bad bump and bruise on one side.. The most concerning thing is almost franticchewing on anything he can get to .. he is 18 months old .. Have we got a girl ????
Alternatively Do nothing - as the cere hypertrophy in itself does not cause problems. Except :Budgie vets also note the long term health issues of chronic hyperoestrogenism including hernias, and other reproductive tract disease but , the cere changes in budgies are not usually an issue, in themselves unless a nare or nostril is blocked.
The blocked nostril , The expert budgerigars vet will remove the Keratin, and unblock the nose, the material in teh sinuses are then flushed out - A sinus flush procedure , and often a vit A injection is given.
It appears to me that sick male budgies often lose the colour in their cere (going almost white), presumably due to a decrease in circulating testosterone as part of a stress response. In other words does the brown cere colour appear because the testes stop producing testosterone, or because they start producing oestrogen?
It is thought that the lack of the female hormone estrogen results in the characteristic blue cere we see, at the Budgie vet, in male budgerigars. . Blue cere changing to brown suggests not so much a lack of testosterone but an excess of estrogen. This is often associated with an estrogen-secreting Sertoli Cell tumor, of the testes.
Cock birds, although nearly always sporting a blue cere, may have a brown or brownish-pink one if his breeding hormones dip, or if he is ill. An ill male may develop a yellow-greenish tinge around the nostrils too. In immature cock budgies the cere is a blueish pink or light purple.
DESCRIPTION: The blue-billed curassow is a large (89-92 centimeters), primarily black bird with a distinctive bill decorated with blue cere and wattles. The male is black with curled black crest feathers, a white vent below its tail, and white on the tip of its tail. Females are black with black and white crest feathers, fine white barring on their wings and tail, and a rust-colored lower belly and undertail.
RANGE: The blue-billed curassow is endemic to the mountain valleys of northern Colombia. Although historically the bird was distributed throughout the northern mountainous region, it is currently confined to a few remnant forest patches, including the west slope of the Serrana de San Lucas, Antioquia and the Serrana de las Quinchas, Boyac.
BREEDING: The bird breeds in Colombia's dry season in the summer and nests between December and March. It has a clutch size of one to two eggs. All cracids are for the most part monogamous and live in pairs.
THREATS: The primary threat to this species is deforestation for the purpose of agriculture, livestock farming, illegal drug plantations, oil extraction, and mining. In addition, the species is threatened by hunting and egg collection.
Male Blue-billed curassows have a slightly swollen cere (a waxy fleshy covering at the base of the upper beak) and wattles that are a bright blue. The plumage is black with a white abdomen. The female also has a blue cere, which is not as swollen in appearance, and her plumage is black with narrow white barring on the feathers, and the abdomen is rufous or rust-colored. Both sexes have a head crest of curled feathers that will stand up during displays of courtship, excitement, or agitation. Females incubate two eggs for up to 32 days while the male guards the area surrounding the nest; both parents take part in the raising of the chicks once hatched.
So, you are a new pet owner in which you acquired a budgie as a pet. Either you forgot to ask the pet shop on which you got the budgie about its gender or the pet budgie is given to you as a gift and the one who gave you do not know its gender as well.
Most birds species that we know are usually difficult to tell whether they are a boy or a girl on just by looking at them. But you are lucky since it is budgies we are talking about. For a new pet owner like you, it might be a bit difficult to determine your budgies gender but there are some simple tips in which we will share to you to help you with this simple problem.
Female budgies on the other hand can be very sweet to you if have taken good care of her and bonded with her a lot and be very aggressive to strangers who they do not know. They tend to be aggressive because they are inclined to defend their territory or their nest. It is their motherly instincts. Females also nibble on things a lot more, like their toys or whatever they have inside their cage.
Their personalities are just a hint about their genders. It can be unreliable on determining their gender because budgies have different personalities depending on how they were raised. Some female budgies might act like a male budgie because she lived with other male budgies before you got them and she just mimicked their behaviors and the same goes if a male budgie lived with females before you got him.
Male budgies will always have a dark blue cere. Unless the budgie is an albino then it is another story. Young budgies will have a purple cere. Give the budgie a few more months to grow, if the purplish cere turns to dark blue then you have a male budgie.
The blue-billed curassow faces several threats in the wild including deforestation, habitat loss, hunting and poaching. The Houston Zoo is one of a few zoos in the United States that breed these critically endangered birds, and we are providing training and support for our conservation colleagues in Colombia to protect them in the wild.
