Northern Lapwing

The northern lapwing, also known as the green plover, is an interesting mix of unrelated parts. It has a short, thin black bill and a very thin black crest which consists of a few strands of feathers, like an old man's comb-over standing up off his head. It has a black crown, throat and breast and some black around and under the eye like the smudgy eye black a football player uses. The back is tinted green with various shades that really stand out in sunlight, from greenish yellow to raspberry, plumb and forest green. It also has dark red legs. 

The black crest is going every which-way. These lapwings were in the Eastern Range of Kaziranga NP. 

The color is in the wings. 

We saw it in its winter range in Kaziranga NP in Assam, India. It also winters in small portions of north Africa, southern Europe and China. It is found year-round in some portions of Europe, like Portugal, England and Ireland and spends summers in northern Europe and mid-Asia.

Light green is summer range, blue is winter range and dark green is year-round. From Wikipedia. 

This lapwing was in the Western Range of Kaziranga. 

This one is really dapper. The crest looks slicked back, it has more white around the eye, and the back is a kaleidoscope of colors.
