directly under foot, nor do they run along the ground first, after the 

 manner of a great many of the ground builders, but keep a good 

 look out, and fly straight from the nest when anyone comes within 

 fifty feet of them. It is needless to say that it takes sharp eyes 

 to discover their exact position. 



At my arrival on the bright, sunny morning of April 24, the

 camera she always came to a halt upon reaching it, and it was

 the nest, looked in, and settled down upon the eggs. An exposure 

 of one twenty-fifth of a second with stop 16 shows her as she was 

 looking into the nest. While I reset my shutter and put in a new 

 plate the Lark left the nest, but this time it took her only two 

 minutes to return. A photograph of a young bird was taken on
