The answer is false.
In middle east countries, falconry is useful to Arabians way back 2000 years ago. The bird was traditionally used for hunting and it was a source of survival in the desert. The humans used its amazing ability to see great distances and to supplement their diet, catching the Habara, or similarly known as a wild turkey in the desert. That is why UAE makes the falcon as their national symbol. Camel is only used as transportation not as a means of survival.
