Those two clutches vary somewhat in size and the depth 

 of marking, but not in any abnormal way ; they are typical 

 Kestrels' eggs. 



Shape rounded oval ; texture fairly smooth ; surface not 

 glossy. 



In colour the ground is whitish, but the whole surface is 

 almost entirely covered by reddish-brown and light liver 

 splashes, streaks, spots, smears, and wash. 



In clutch 1 the smallest egg is rather lighter in colouring 

 than the rest. 



In clutch 2 the colour is generally slightly darker than in 

 clutch 1, and in two of the eggs the heaviest markings lie 

 towards the narrow end.
