 the Golden Plover. 



It ranges from the arctic regions to South America, being common on the 

 Atlantic coast during migrations. It breeds in the far North ; the eggs are 

 usually four, pale olive brown, spotted and speckled with brown and black. 

 The note is a soft whistle, si-sol, of the scale.
