They do cast shadows.
The birds flying in the sky do not cast their shadow on the earth because the umbra is absent and the penumbra is too large and too faint that it is not visible as the distance of the earth is very large from the bird.
If I understand you correctly, you are saying that a bird flying in the sky does not have a shadow. If this is the case, it is not true. Birds do have shadows. I have noticed shadows of birds flying overhead, like a hawk, for example. I believe, that for small birds, the shadows are probably so small we just don't notice them.
Birds flying up in the sky do not cast their shadow because the source of light (sun) is too large compared to the object (bird) and the umbra of the shadow formed on the screen (ground) is very small, negligible.So it is tough to see its shadow on the ground. (P.S. If this is a VNS student reading this for Physics research, then I'm pretty sure you're in my grade and you know who I am)
