Why are male birds more likely to help care for their babies than male mammals do?
well birds get eating more than mammals so they help care more.
Can you spay or neuter a male green cheeked conure?
Birds are not mammals, but it should be possible.
Is it bad to have testicles?
No, certainly not. All male reptiles, birds and mammals have testicles; they are the organ in which the sperm are made.
What is the sex chromosomes of male?
In humans and other mammals, a male has XY sex chromosomes. In birds, a male has XX chromosomes. In amphibians, male chromosomes look the same as female chromosomes.
Do penguins reproduce sexually or asexually?
Like all birds, fish and mammals - they produce sexually. They need a male & a female to reproduce the species.
Are mammals only girls?
No. A mammal is a group name for a group of animals, just like reptiles, amphibians, birds, and fish. Humans are mammals, even the males.
How do fur seals breed'?
Fur seals are mammals and breed like all mammals, through male sperm fertilization of female eggs.Seals are mammals, so mothers carry their young in the womb and pups are born alive to be nurtured by their parents.
Are penguins mammals or birds?
Penguins are flightless birds. However, like marine mammals, they are able to swim underwater for long periods. Rather than milk, they feed their young regurgitated fish. In some species, notably the Emperor penguins, the male (who fasts while incubating the egg alone) can regurgitate a fatty substance for a newborn to eat in lieu of food.
How do Antarctic Fur Seals breed?
Fur seals are mammals and breed like all mammals, through male sperm fertilization of female eggs.Seals are mammals, so mothers carry their young in the womb and pups are born alive to be nurtured by their parents.
How are birds different from mammals?
Birds are warm-blooded like mammals and lay eggs as some mammals do. But mammals are characterized as nursing their young, which no birds do (although some male penguins have a way of feeding newborns). Birds are also different from most mammals in these ways: 1) Birds have wings, although some can't fly (penguins, emus, ostriches) 2) They have feathers to aid with flying and waterproofing. Most mammals have fur or hair all over their body. 3) They lay eggs which are fertilized inside of the females (the eggs come out in the same form whether fertilized or not). 4) They have hollow bones whereas mammals have filled bones. 5) Most have a beak or a bill of some kind. 6) The shape of the body: most often a teardrop-shaped body and a long neck with two legs. Most mammals have four limbs with paws or feet to walk on. 7) Most birds have claws and a three-toed foot with the extra toe at the back.
Which pair of chromosomes produces a male off-springs?
It depends which species you are. There is the XY system (which mammals use) where it is the presence of the Y chromosome that induces male development. The Y chromosome contains genes like Sry that initiate the male developmental program. Male mammals have an X and a Y chromosome, female mammals have two X chromosomes. However, for other species, like birds, use the so-called ZW sex chromosome system where it is actually the absence of the W chromosome that permits male development - male birds have two Z chromosomes and female birds have a W and a Z chromosome. And then there's the X0 system, which many insects use, where two copies of an X chromosome results in a female but a single copy of an X chromosome results in a male.
How do the roles of male polar bears differ than female polar bears?
I think you need to have a talk with your parents about the birds and the bears
