scientists call a biological clock—when a change in weather is about to occur

 Modern research shows that birds and fish can predict weather conditions—they have an innate system that modern scientists call a biological clock—when a change in weather is about to occur. So the sparrows and fishes are aware of them in advance and they make arrangements to protect them.

Napoleon's forces were destroyed by snow on the Russian border in 1812-the same was true of Hitler's forces when they reached Stalingrad in 1941 but were killed by heavy snow-

How strange that Napoleon's and Hitler's armies could not predict the Russian snowfall-and the Siberian sparrows in Russia would have predicted the snow season and left Siberia ahead of time. and after a long flight, they go to warmer regions (India, Africa, etc.). -

Isn't this proof that there is someone who knows more than "Napoleon" and "Hitler" who tells the sparrows under his knowledge what the sparrows cannot know by themselves?
