Swallow, on the contrary, is open at the top, probably because 

 the long forked tail would be crushed if pressed info so small a 

 compass, while the shorter and simpler tail of the martin does

Wherever it can find an old chimney, the Swallow will always 

 build its nest therein, a habit which has gained for the bird the 

 popular title of Chimney Swallow. It will, however, build in 

 many other situations, such as precipitous rocks and quarries, 

 barns, outhouses, and steeples. There are usually five eggs, and 

 the nest is lined with a soft bed of feathers, like that of the 

 martin.
