The shadow is there, but it is 'diluted' until practical invisibleness; spreading over a very big area and proportionally becoming lighter. Projection is a keyword here:
The shadow is projected unto the nearest surface. If it is very close, the shadow is very dark. But there is only that much 'darkness' in a shadow. If the object is moved farther from the surface (e.g. the bird flying higher) the shadow becomes bigger, but less dense. The shadow is diluted until invisibleness, the smaller the rising bird, the faster. Try throwing an object up in the air in sunshine and see the effect.
This explanation is true, but get a physics teacher explain it more scientifically correct.
They do cast shadows.
Flying birds do cast shadows. It's just that the distance from the earth makes them barely visible.
Predatory birds often cast shadows. Many other animals interpret all shadows as a threat to them, and flee.
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)
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.

Cast and form shadows: -Cast shadows are just typical shadows that are created when light is blocked by an object. -Form shadows are the shadows that are on the object and away from the light source. Usually, in painting, cast shadows are used to give an object a more realistic and 3D look to them.
