Red-necked Grebe

Podiceps grisegena

The red-necked grebe is an aquatic bird found in the temperate regions of the northern hemisphere. A migratory bird, its wintering habitat is largely restricted to calm waters just beyond the waves around ocean coasts, although some birds may winter on large lakes. Grebes prefer shallow bodies of fresh water such as lakes, marshes or fish-ponds as breeding sites. Source
