Nearly all non-mammal vertebrates have nucleated red blood cells (nRBC). Non-nucleated RBC's are a unique feature to mammals. There are of course a few notable exceptions, such as the artiodactyl order, which have an odd blood morphology.
all mammals except camels and llamas have enucleated mature RBCs

Yes, the red blood cells of birds are nucleated.
Areolar connective tissue contains various types of cells, including nucleated cells such as fibroblasts and immune cells. However, loose connective tissue is a broader term that encompasses various types of connective tissues, some of which may not contain nucleated cells. Examples of loose connective tissues without nucleated cells include adipose tissue (which primarily consists of fat cells) and cartilage.
red blood cells that have not lost their nucleus.
Not all are. Many biologists believe that bacteria are alive, and they do not have a nucleus. Also, though there is some debate, viruses are also sometimes considered alive, and not only do they not have a nucleus, they do not even have a plasma membrane. The definition of what is alive and what is not is quite complex and goes beyond nucleated cells called eucaryotes and non-nucleated cells called procaryotes.The red blood cells in your body are not nucleated.
White blood cells carry genetic information. In mammals mature red blood cells do not have DNA because they do not have nuclei. They expel them during the maturation process. However, in birds and reptiles they have nucleated red blood cells. Thus reptile and bird red blood cells do contain DNA.
The red blood cells of all mammals, without exception, are anucleated (lacking a nucleus). Mammal RBCs are nucleated only during embryonic stages. The red blood cells of camels are oval instead of round so they can withstand the effects of water deprivation better.
Yes, the red blood cells of birds are nucleated.
llamas are camelids. Camelids can have a small number of nucleated red blood cells. But their red blood cells are elliptical rather than round.
They are nucleated. Mammels lack nuclei in mature red blood cells.
A reticulate red blood cell, or reticulocyte, is an immature red blood cell. In mammals, reticulocytes do not have a nucleus. They are slightly larger and appear more blue in colour (with standard stain) than mature red blood cells. A nucleated red blood cell is one which contains a nucleus. Mature mammalian red blood cells do not have a nucleus. In mammals, nucleated red blood cells are more immature than reticulocytes - and are not normally seen in peripheral circulation. They can be a sign of anaemia if seen on a blood smear. Birds and reptiles have nucleated mature red blood cells.

NRBC stands for Nucleated Red Blood Cells.

Examples of loose connective tissues without nucleated cells include adipose tissue (which primarily consists of fat cells) and cartilage.
It is called SOMATIC cells or body cells. A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent.
