What's his daily income? How much？

[asdfzzpsx]

Joseph Sekar is a 62-year-old man in India. He feeds thousands of birds every day. And he has earned himself the nick name '"birdman".
Joseph always left small amounts of rice on his roof. The birds often came to eat them. One day two parrots flew in and fed them some rice. The birds not only returned the following day, but also brought along other hungry trie nds. Today betwee n 2,000-4,000 beautiful parrots visit the birdman twice a day!
Joseph does not feed the birds raw rice, He cooks them! This means that the amazing man gets up at 4:30 am every morning and spends over an hour making the breakfast. He then spreads the rice across 14 wooden planks （厚木板）on his roof.
The breakfast rush begins at about 6:00 am when the beautiful parrots fly in and continues until every last grain of the delicious rice is gone! The ritual （老习惯）is repeated in the evening when the birds arrive around 4:00 pm and stay for almost two hours. Besides feeding them, the superhero also takes in sick or injured birds and nurses them back to health.
Of course, feeding so many birds is not a cheap job. Joseph spends 40% of his daily income of $ 13 as a camera repairman on the meals. The generous man says all of his actions come out of a sense of love.
