Have you ever seen a bird fly into a building?Now，a group of students from Class 6，Grade 8 at Shenzhen Baoan Hangrui Middle School，Guangdong，are working to help the birds and learn more about this problem.
In March，they set up a team to study bird collisions（鸟撞）. "Every morning，we walk around buildings with large glass before 9 am. That is the peak（高峰）time for bird activity. "Feng Yongyin，14，told Teens. If they see a bird that has hit a building，they take photos of the bird as well as the area around it. Then，they put the photos onto an app called Biotracks. Scientists can use the information to do more study.
The students' careful watching of the birds has also made the school think about moving the basketball court（场地）. That's because it is an area with many plants and birds. "Once we found a fallen bird's nest（果） in the area and put it back. We also set up a camera，"said 14﹣year﹣old Lan Zijia. Using the camera，they saw that many students went into the area to get their balls. "We told the school about this，and the school has put a line to protect the plants and birds. We might have to do more things in the future. "Lan said.
Since March，the team has done 416 studies，found five bird collisions and saved one bird. "I feel proud of what we have done and want to keep helping birds and people live together peacefully. "said 13﹣year﹣old Li Yinuo.
