     The swallows of Capistrano may be famous for returning to the same nests each spring. But they have

nothing on the purple martins (紫燕). These beautiful birds spend each winter in the warm climate of south

America,then return each spring to nesting places in the Southeastern United States.

     Purple martlns are birds that are pleasant to watch. Many people also like to have the martins around

because the birds control insect pests. If hollow gourds (葫芦) with two-inch open spaces are hung out for

them,martins are happy to move in. They require only small open spaces to discourage wild animals from

eating them. The gourds should also be hung in an open place away from buildings or trees,so squirrels or

cats can't disturb the birds.

     Common garden grown gourds sometimes rot (腐烂) in the climate of the southeast, so many purple

martin lovers have tried using different materials to create stronger nest. Lengths of plastic pipe have been

used, along with old-fashioned wooden bird houses with martin-sized entrance holes,but the birds clearly

prefer the shape of a gourd. One company is now selling a plastic gourd, just the right size and shape with

a two-inch entrance hole for the martins. The hole is high enough to allow the martins about four inches.

The plastic gourd can be used for a long time.

     The permanent (永久的)state is important for martin lovers because the birds can become almost part of

the family. Some families have had the same groups of martins returning to their yards each year for sixty

days.
