Budgie Lifecycle

In the wild, budgerigars usually breed in response to rainfall (so you would imagine the breeding urge is always strong in UK aviaries!) This is generally between June and January, although they will seize the opportunity whenever it crops up. With water and food temporarily in abundance, the birds can take time out from their nomadic lifestyle and settle down. If the water and food supply allows, the birds will go with the flow and produce several broods one after the other.

Budgerigar nests are an object lesson in simplicity – a bare tree cavity with enough space to fit one adult and between five and eight white, circular eggs. Sometimes a fence post substitutes for a tree, and occasionally a log on the ground is chosen. It’s the female alone who sits on the clutch, with the male providing the duties of an eager-to-please waiter, bringing food for his partner. He regurgitates a porridge of leaves and seeds for her to feast on, and continues to bring food throughout the weaning period.

After 17-19 days, the eggs hatch, one at a time over a one-week period. Budgies are born naked, blind and helpless, like all parrots (and many other birds too). The first meal they receive is a liquid from the hen’s crop, sometimes referred to as budgie milk. This contains essential nutrients and antibodies, the avian equivalent of mammals’ milk. Nature has even equipped the hen to vary the contents and consistency of this fluid as she feeds her brood in the first week, from youngest to eldest, ensuring that each age group gets exactly the nutrients it needs.

From dawn until dusk the cock bird flies back and forth, filling his crop with seeds and regurgitating them for his mate, who then delivers the best of the crop to the chicks. The male begins to feed his offspring directly after about three weeks (although sometimes an over-protective female won’t allow this, and goes it alone for the entire fledging).

There are always birds of different sizes in the nest, as the hen staggers her egg-laying. Unlike in many species, where the later chicks are a kind of insurance policy, discarded if the first-born thrive, the survival chances of the younger budgies are very good. Once they are hatched, the hen instinctively feeds them first rather than the pushy elder members of the brood. In captivity these later eggs are sometimes removed and given to a surrogate broody pair to hatch.

Budgie chicks can hold up their heads after seven days, and their eyes open after ten. They grow soft down to help them keep warm at this point, with a covering of ‘pin feathers’ appearing at two weeks. These are thin, scaly stubs that will later blossom, flower-like, into beautiful budgerigar feathers. This happens between three and four weeks, and the birds are weaned and ready to leave the nest between 30 and 40 days after hatching. It’s a full nine months before they’re completely independent.

At a year old, budgies are ready to breed, and the cycle begins again. As with any bird species which has both parents investing a considerable chunk of time in the rearing of young, a budgerigar couple are strongly bonded, with a ritual romance involving all manner of mutual grooming, beak ‘kissing’ and head bobbing.

Budgie Lifespan

Budgies generally live between five and eight years in the wild, but commonly make it to somewhere between 10 and 15 in captivity. One exceptional specimen clocked up over 29 years.

I was wondering if i should take my 33 day old budgie out of its nest and remove the nest box (everything required for it is provided. Bath, food, flat ground, low perch, etc.) as it can already fly and walk ? Please answer as soon as possible

My male budgie is 11 years old. I just bought a baby budgie and currently have them in separate cages. I do not know the sex of the new baby. Can I eventually put them in the same cage?

My Budgie is currently 24 years old! I love him so much!! He was lying on the bottom of the cage twice this month! Made me so sad. We live in NY, so I assume it is caused by weather. I moved him to inside walls in his cage and he is now tweeting away!! I think it was the cold two times.. Keep them warm!!
