There are five different types of bone in a human body. If you are talking about long bones, such as your femur or tibia (aka the long bones in your arms and legs), then in the middle of them are bone marrow. Yellow marrow for adults and red marrow for children.
In the middle of your bones is soft tissue that is spongey and it is called bone marrow.

Bone marrow
Red bone marrow, which produces blood cells, is found in the spongy bone of long bones, such as the femur.
Yellow marrow is located in long or short bones. Yellow bone marrow is found in the hollow interior of the middle portion of the bones. During severe blood loss, the body can convert yellow marrow to red marrow.Yellow marrow is found in the hollow interior of the diaphyseal portion or the shaft of long bones. By the time a person reaches old age, nearly all of the red marrow is replaced by yellow marrow. However, the yellow marrow can revert to red if there is increased demand for red blood cells, such as in instances of blood loss.
At birth, all bone marrow is red. With age, more and more of it is converted to the yellow type. About half of adult bone marrow is red. Red marrow is found mainly in the flat bones, such as the hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous ("spongy") material at the epiphyseal ends of the long bones such as the femur and humerus. Yellow marrow is found in the hollow interior of the middle portion of long bones.

The hollow part of bones are mostly filled with Red Marrow
No - they contain marrow
Birds have hollow bones that make them lighter so they can fly more easily.
Red bone marrow is found in places with flatter bones, such as hip bones, along the end in a sponge-like material at the ends of bones. Yellow bone marrow, on the other hand, is found in the center interior portion of longer bones.

Most long bones are found in the limbs.

they oth have long hollow tubes like bones.
An emu's bones are solid and adapted for long periods of running and walking. A seagull's bones are light and hollow so they can fly easily.
