The best way to find answer to all of your question is to keep watching the robins,” said Miss Hill. “Would you like to keep diary that tells what you see each day?”
The children said they would. Here is part of their diary.
Apr, 12 Mr. And Mrs. Robin began their nest today. They haunted for string, dead grass, and straw. They wove the nest like a tiny basket.
Apr, 13. The robins carried mud in their bills. They spread it inside the nest. One of them got in and turned round and round to smooth the mud
Apr, 15. The mud lining is dry. The birds brought soft grass and roots to make a soft lining for the nest.
Apr, 17. One blue egg is in the nest
Each day the children had something new to report. One boy or girl wrote it on a sheet of chart papper
