SITUATION - While walking along the James 

 River, I saw this bird fly to a spot among 

 some rather large rocks on the riverbank and 

 disappear. On investigating the site, I found 

 a two inch opening in the soft earth from 

 which theswallow suddenly flushed. Inspection 

 revealed a one foot tunnel which the birds had 

 made between the rocks, that led to a chamber 

 which held the nest. The diameter of this ter- 

 minus of the tunnel was just adequate to acco 

 modate the 3-V nest, which was composed of 

 dry grasses and lined with finer grasses and 

 horsehair, but no feathers. I got a good look 

 at the bird and feel confident of its identity 

 In addition, there was no evidence of any other 

 swallows in that section. 



The six white fresh eggs long 

 and oval, with a slight gloss - all of which 

 made them appear almost translucent.
