Golden Eagles and Gray Wolves Reproduction
This essay is about reproduction on Golden Eagles and Gray wolves. This will tell you about the Development, How many offsprings after they are born/hatched? How long the parents look after the offspring after they are born/hatched? and much more.
Golden Eagles are monogamous (have only one mate) and they pair for life, but if either of them dies, the one left will accept a new mate. Home range is an area of their territory few nesting sites and often with a choice of two or three spare nest sites, called eyries. Both Eagles build the nest, which is built from branches, twigs and feather, with woodrush and grass at the bottom, and decorated with green foliage.
The fertilisation is Internal while the development is external.
The female Usually lays two eggs 3-4 days apart in March, and them for 43-45 days. Incubation starts with the first egg, and the two chicks hatch a few days apart. The first chick to hatch is dominant over the younger one,only has a 20% chance of surviving the important first weeks of their lives.
The female does most of the babysitting, which is for warmth, protection, or cover young with the wings or body and feeding of the offsprings, while the male supply the female and the young with all the food they need, especially in the early stages of life for the offsprings. She baby sits the chicks almost non-stop for the first two weeks. After this, she will regularly leave the nest and share the hunting with the male.
The Offspring will fledge when they are about 65-70 days old, and will become independent after 90-100 days. Young golden eagles at times stay with their parents until November or December but are usually Forced to find their own nest by October. The...

...ow rate of survival. Therefore Gray wolves have a higher survival rate than the Golden Eagle, 40%vs20%.
In conclusion Gray Wolves and Golden Eagles are monogamous, their mothers looks after the newborn initially. However Gray Wolves seems to have a higher survival rate than the Golden Eagles could be contributed by more members would share the responsibility of well being the pups.
