Are Rabbits as Prolific as Everybody Says? End of dialog window. The real wow factor of rabbit reproduction is how fast they get around to breeding, and how often they can do it. The average rabbit reaches sexual maturity at 3-8 months old, and they have the rest of their 9-to-12+ years to get it on (though egg/sperm production drops off at around 3 years). Their breeding season lasts three-quarters of the year, and the does don't have an estrous or heat cycle. They're more or less ready to mate all the time.

Zebra Finch Breeding Basic Breeding. Zebra finches are a joy to watch as they prepare their nest and raise their young. The mating dance and song of the male is fun to watch and is a good indication that they are happy and ready to breed. The male ‘sings’ and bounces on the perch to attract the hen.-6 weeks old move the chicks to their own cage. They will disrupt the next clutch process and the parents may start to pluck their feathers. Zebra finches live to be 4-8 years of age. I have heard of birds living to 10 and 12 years old, but I think this is rare.

The Differences Between a Crow & a Grackle Crows lay larger and more eggs, averaging three to nine, compared to the grackle's one to seven. Crow eggs incubate as much as a week longer than grackle eggs. Once hatched, crow chicks stay in the nest 20 to 40 days, more than twice as long as grackle chicks at 10 to 17 days.

SQUIRRELS These squirrels mate from January to March and again from June to July, and the gestation period is 44 days. Females, two years of age and older, may bear two litters each year. Males begin to reproduce at 18 months old. In a typical year, about 60 percent of the fall population will be young that were born that year.

How long do bird's live? Large birds - crows, , birds of prey- regularly live for 10 years and more in the wild and 20-40+ years in an aviary. Many seabirds live for 20-50 years in the wild. Large species of parrot routinely live for over 20 years in the wild and over 50 in an aviary. Normal clutch size and age at sexual maturity are excellent indicators of mortality rate/life expectancy. Cranes and large birds of prey will not breed until 3-4-5-6 years old and rear only 1 or 2 chicks in one year.

Cicadidae When they are mature, they climb out of the ground and complete one final molt. They emerge as an adult cicada with wings, and fly away to find a mate. Once they become an adult they stop growing and do not molt again. Some of the species that take 13 or 17 years all come out of the ground at one time.

Reproduction Grizzly bears are even less productive: in 10 years, a male a female born today could grow to a population of only eight. By comparison, a pair of white-tailed deer could produce more than 1,400 descendants in 10 years. Bears generally live solitary lives, but can be found together during mating season. The average breeding age for female black bears is 3.5 years and for female grizzlies is 4.5 years. Males reach sexual maturity at roughly the same age as their female counterparts.
