ROCK-DOVfi. 347 



ftest. Composed only of a few sticks or roots, and very 

 frequently there is none at all, the eggs being laid on the wood 

 at the bottom of a hole, or on the bare sand in a rabbit-burrow. 

 Mr. Robert Read writes to me : "I have found fresh eggs of 

 this bird in Somersetshire as early as March and as late as 

 September, in both instances in the hollow head of a pollard 

 willow. I have also taken the nest from a rabbit-hole in a 

 wooded hill-side." The species also breeds in holes of trees 

 and cliffs, on beams in old church towers, old nests of other 

 birds, and squirrel's dreys. 



Eggs. Two. Pure glossy white. Axis, 1-5-1*65 inches; 

 diam., ri-i'25.
