From late autumn and during winter, the coastal wetlands of Greece attract two species of plovers that is difficult to distinguish their differences. Golden plovers (Pluvialis apricaria) and grey plovers (Pluvialis squatarola) visit Greece in small groups or solitary and their coexistence is not a common sight, as they appear in relatively different seasons. So their differences are easier to distinct when they appear together. To the left of the photo is the slightly smaller golden plover with the golden color, the small beak and the narrow wings and to the right is the larger grey plover with the gray colors, the heavy beak and the large wings. Apart from the morphological differences, the two species also present different behavior. The golden plover is more suspicious and prefers fields and mudlands and the grey plovers is more fearless and is found exclusively in shallow lagoons and coastlines.
