Do birds have blood? If not what do they have? Wondering why they don't freeze solid here in central Minnesota

Answer 1

You Gotta Be Kidding Me Buddy...

Winter is not an easy time for birds. Not all of them are genetically programmed to head south for the duration. Imagine if you had to stay outside in freezing weather the entire winter! A bird-friendly habitat may make the difference to their survival.

The birds that visit your neighborhood vary with the seasons-not only the species, but also the individuals. Some species, such as downy woodpeckers, may be year-round residents. Others-dark-eyed juncos and ruddy ducks for example, are winter visitors. You will see hummingbirds only from late spring until early fall. Species such as rose-breasted grosbeaks may visit only during spring and fall migration. Robins may migrate only a few miles, and return temporarily if the weather becomes milder.

Many birds flock together for survival in the winter. The ones that seem to be most noticeable are starlings and crows. Starlings may gather by the thousands. Once they have flocked, breaking up the flock may mean death to many of its members. Practice and teach tolerance. The most effective way to prevent flocking is to change the habitat, but this should be done in the warm season.

glycerin and antifreeze will kill birds!!!

Answer 2

Yes, birds have blood. The average mammal body temp is 37 C, where as the average bird body temp is 39 C, but this is not the only reason why they don't "freeze solid in central Minnesota". Birds have very good insulation with different kinds of feathers that keep them warm. In their legs, which are bare and exposed to the elements, is a system of blood vessels where the arteries and veins exchange heat so that the heat is not lost very much through the feet.

Answer 3

Do Birds Have Blood

Answer 4

Birds have different blood than mammals. Mammalian blood is produced in the bone marrow, and the red blood cells do not have nuclei at their mature stage, so they can't reproduce by dividing. Birds have very little bone marrow (hollow bones help them be light enough to fly) and so they have nucleated red blood cells that can reproduce by mitosis (dividing). They can. like any animal, freeze during the winter, but most have strategies to avoid it.

Answer 5

Birds certainly do have blood, and that's exactly what allows them to withstand low temperatures. A combination of high metabolism that keeps their body temperature high and down/feathers that act like an insulator keeps them warm.

Answer 6

Yes, birds have blood.

Answer 7

Answer 8

AS BIRDS HAVE A HEART, THEN YES THEY DO HAVE BLOOD. I COULD ONLY SUGGEST THAT THEY DONT FREEZE IN MINNESTOA BECAUSE THEIR BLOOD PUMPS FASTER, THUS HELPING KEEP THEM WARM.

Answer 9

of course birds have blood- they also have down(feathers and oils) that trap heat and help them regulate heat-

Answer 10

of course they have blood...It's chemically different than ours and allows them to withstand the harsh conditions.
