1 84 BIRDS 



enjoyable experiences in Birdland with which I 

 am acquainted. 



As you get to know the eggs of some of our 

 commoner British birds you will be amazed how 

 they vary in size, shape, colour, and markings. 

 It is interesting to compare some of these, and 

 illustrations of a few are given in this book, as well 

 as a stereoscopic photograph of the eggs of the 

 Kestrel and the Sparrow Hawk. Birds' eggs, 

 thus looked at, have a beautiful effect, and I offer 

 the following suggestions of further comparisons 

 that might be made with both pleasure and 

 profit : — 



1. Goldfinch and Bullfinch 



to show difference in size. 



2. Wheatear and Stonechat 



to show difference in size. 



3. Chaffinch and Greenfinch 



to show difference in size. 



4. A Series of Tree Pipits 



to show difference in markings, etc. 



5. Reed Bunting and Yellow Bunting 



to show difference in markings. 



6. Spotted Flycatcher and Robin 



to show similarity of some varieties. 



7. Swallow, House Martin, and Sand Martin 



to show difference in colour, markings, size, and 

 shape. 



8. Wryneck and Lesser Spotted Woodpecker 



to show similarity. 



9. Pied Wagtail and House Sparrow 



to show similarity of some varieties.
