Here in the Brecks – an area of poor, sandy soils on the borders of Norfolk and Suffolk – we have a small but important breeding population. They favour the old heaths, but a number of pairs also breed on farmland. Brettenham Heath National Nature Reserve holds the highest density of nesting Curlews in the Brecks.

Black-tailed godwits winter in large numbers on the estuaries of both Norfolk and Suffolk, and we know that nearly all these birds breed in Iceland. In breeding plumage islandica godwits develop a deeper red plumage than their limosa cousins. They are of the race islandica , a sub species of the nominate race, limosa.

The source of this ranking, BirdLife International, lists Bolivia as currently having 1,439 bird species, including 18 breeding endemics. But, the numbers are quite large, and the birds organized in groupings that, for the most part, make it an easy process to figure out which Antwren (or Woodcreeper or Seedeater) is which.

The seasonal life of one bird species is complex; life cycle events like aging, breeding, molt, and migration are intricately tied to habitat, food availability, genetic ‘instincts,’ hours of daylight, and weather. But a lot will be new, particularly the many studies that prove these are real changes supported by hard data.

If migration evolved many times in birds, then it would be worth asking if it evolved in birds more often than in other groups of vertebrates. Loons hardly ever fly when they are on their breeding grounds or their winter-water, but the migration is for many loons a non-trivial distance. Consider the implications. 2 PIERSMA, T.,
