The desert is a very hot and dry climate. Very little rainfalls every year happen. Plus there are king scorpions, spider, and not many birds. At night, it gets really freezing.
To find the number of birds in the sanctuary next year, you add the annual increase to the current population. Starting with 150 birds and an increase of 14, the calculation is: 150 + 14 = 164. Therefore, there will be 164 birds in the sanctuary next year.
About 1 billion birds are killed in the US every year so possibly, 5 to 10 billion birds per year. As for per day, possibly 1 to 10,000 birds.
