water during the daytime, and under no 

 circumstances to visit the river beds. The 

 Grey Duck's nesting sites are more diffuse: 

 by lake edge, river brim, and far from 

 water, even not very rarely on trees their 

 eggs may be discovered. During the day 

 they often rest on flat shore lands, or 

 swim close along the raupo edge. No one 

 of these breeds interferes with the other, 

 nor do theii' nesting places overlap.
