Original: Citizen science involves compiling information that has been collected and provided by volunteers or citizen scientists. And the professor gave an example of an organization that accounts wild birds. They want to know how many wild birds and how many species of wild birds in the U.S. But the U.S. is very big and it's only a very small step, so it's hard for them to account all of the birds. So there are a lot of people who identify birds just for fun. So every year these people focus on accounting birds and they send information to this organization. And thousands of people do the same thing every year. So the organization could get regular information and they could focus on the way to protect the birds if the numbers of them are declined.

Corrected: Citizen science involves compiling information collected and provided by volunteers or citizen scientists. The professor gave an example of an organization that monitors wild birds. They want to know the number of wild birds and different species in the U.S. However, since the U.S. is vast and they have limited resources, it's challenging for them to count all the birds. Many people identify birds as a hobby, so every year, these individuals focus on counting birds and send their findings to this organization. Thousands of people participate in this activity annually, allowing the organization to receive regular updates on bird populations and implement conservation efforts if any species' numbers decline. (在这个修改后的版本中，我们使用了更自然的语言表达，修正了一些语法错误，并增加了一些连接词以使句子之间的衔接更自然。同时，我们还对一些词汇进行了替换，使其更贴切。)

Revised Answer (140 words): Citizen science involves compiling information collected and provided by volunteers or citizen scientists. The professor gave an example of an organization that monitors wild birds, aiming to determine the number of birds and different species in the U.S. However, due to the vastness of the country and limited resources, it's challenging for them to count all the birds. Many people identify birds as a hobby, so every year, these individuals focus on counting birds and send their findings to this organization. Thousands of people participate in this activity annually, allowing the organization to receive regular updates on bird populations. This data enables them to implement conservation efforts if any species' numbers decline, ensuring the protection and preservation of various bird species across the country.
