full but leaves it "on the outside of the hole for her to carry in and 

 arrange. 



"The female begins by bringing some fine straws or grasses 

 which are arranged in a nice nest in the bottom of the hole. Next 

 she procures some fine strips of grape-vine bark, and lines her nest, 

 and lastly covers this all over carefully and thickly with moss which 

 grows on the bark of trees standing in the water. * * * They 

 very rarely use any feathers or hair, and sometimes build their nest 

 entirely of one of the above materials." (Barnes^.) 



Nests collected by Wayne in South Carolina were made of lichens 

 and lined with cypress leaves (C W. C). 



Ganier (MS.) writes that in Mississippi the birds "frequently 

 .excavate their ozvn hole in the soft cottonwood stumps," a habit not 

 mentioned by other writers I have consulted.
