scarce and they had to return to the south. A newer theory is that increasing   
daylight stimulates certain glands(腺)in the bird’s body and prepares it for   
migration. One scientist is able to make birds migrate in midwinter by ex posing   
them for two months to artificial daylight. Recoveries of marked birds indicate   
that they fly north as soon as they are set free. The conclusion is that the urge   
to migrate is determined by changes in the bird’s body which take place under   
seasonal changes in the length of daylight. This theory would account for the   
fact that not all birds migrate at the same time. Each species seems to have its   
own schedule. The theory would also account for the regular time and routes of   
migration. Birds arrive at a given place year after year. Unfavorable weather   
delays them only a few days. Total hours of daylight, rather than weather, start   
them on the way. How birds find their way to the same place year and why they   
follow their own particular route are still mysteries. They evidently do not   
follow known landmarks(地面标志),for many young birds migrate alone without the   
help of experienced adults.
