Eggs of the Common Whitethroat in the large series in the 

 Collection vary from a pointed to a blunt oval shape and are slightly 

 gloss}'. The ground-colour ranges from pale buff to pale grey 

 and from greenish-white to pale green. The markings consist of 

 specks, spots, and blotches of various shades of grey, olive-brown, 

 olive-green, umber- brown, and underlying lavender, and whereas in 

 many examples these are evenly distributed over the whole shell, 

 in others they are chiefly confined to the broader half of the e^g., 

 where they are often confluent and form a dense cap or zone. 

 Some eggs are comparatively faintly marked, others have the 

 markings very dark. Specimens measure from 'Go to '8 in length, 

 and from "5 to '6 in breadth.
