Share to ClassroomStudy: Swifts Keep Same Nests
A new study looks at small birds called swifts. Swifts come to Britain every summer. The study shows the birds are very loyal. Most swifts go back to the same nest each year.
But swifts are in danger in Britain. There are far fewer swifts than before. Many lose their nests when people fix old roofs. Swifts cannot easily find a new home.
Now people want to help the swifts. Builders can add special "swift bricks" to new homes. The birds can nest in these bricks. Many groups also hold events to save swifts.
