are crested. ‘These are all near Vanellus proper, and a part of them are 4-toed. Our species 
are found along the seashore, by the water’s edge in other open places, and in dry plains and 
fields. They all perform extensive migrations, appearing with great regularity in the spring 
and fall, and most of them breed far northward. They are all more or less gregarious, except 
.when breeding. They run and fly with great rapidity ; the voice is a mellow whistle; the 
food is chietly of an animal nature. The eggs are commonly four in number, speckled, very 
large at one end and pointed at the other, placed with the small ends together in a slight nest 
or mere depression in the ground. ‘The sexes are generally similar, but the changes with age 
and season are great.
