It depends on the individual bird involved. Just like humans, some parrots are smarter than others; some learn things quicker than others, etc. In general, a parrot has the intelligence level of about a 1- or 2-year-old human child. If you observe parrots over a long period of time (years), you'll find that most are very intelligent... they have to be in order to survive.
25
5 years
In terms of human age milestones, 25 is generally considered to be an adult age. By this time, individuals have typically completed their education, entered the workforce, and taken on more responsibilities.
Humans lose 500 neurons per hour. So, yes in terms of physical number of neurons.
A parrot eg (cockatoos, conure, macaws, etc) can have chilli peppers at any age from the time they start eating till they get old. Chilli peppers are not hot for parrots as parrots have no saliva so they can not taste how hot the chilli pepper is. Chilli peppers also help the parrot with mimicking human voice(speaking.)
There are two aspects to this answer. If you are referring to Jesus' age in terms of the age from when He was born on the earth in 4 or 5 BC then that would be 2013 or 2014 years However, since Jesus is the eternal Son of God who was 'in the beginning with God' (John 1:1) then there is no answer as He is eternal. He always was and so has no age in human terms but is, if one must use time, of infinite age.
You have the First Agricultural Revolution, the Neolithic Revolution, the Birth of Civilization and New Stone Age.

This varies from species to species. Generally the smaller birds mature quicker and can therefor breed at a younger age. Some finches can successfully breed at 6 months of age and some of them should be one year. Budgies should be about a year of age, but they could be a couple of months younger and still have healthy babies. Lovebirds, cockatiels and similar sized parrots should be 18 months before breeding. Amazon parrots, African Grey parrots and similar sized parrots mature and can breed at about 4 years of age. The large macaws will be 5 years or more before they will successfully breed. Any of these species can breed at younger ages and may even have healthy babies, but breeding younger, more often produces small, unhealthy babies that may not survive.
