Well with no picture I can't help, but just describe the birds as you see it! :)
Refraction is the change in the direction of the wave passing from one medium to another.
The change in the direction of the propagation of any wave is due to the different speed at different points.
A far away object appears closer and a small object appears larger.
Take an example. Suppose, an object lies in water.
A far away object appears closer. The angle from which the rays of light reach the observer is larger than the angle that it makes in air.
This makes the angular size larger to the observer's eye which makes the object look larger relative what it looks in air. Similar but vice versa condition occurs in the case when a small object appears larger.
Hey!
Vincent van Gogh was the one who painted this, he named it "Starry Night". It's an appropriate name due to the stars that can be seen in the sky. Since he was a post-impressionist, that explains why the paint strokes <span>can be seen so small and thin</span><span>. That was very uncommon compared to regular paintings during that time.
