Nisaetus nipalensis

The most obvious feature of the eagle is the long black crest behind its head, which is much more prominent than the crest of the brown-bellied falcon, and often stands vertically on its head. Males and females are similar. It has a long crest and very wide wings. When flying, you can see parallel black thick horizontal stripes under its wings, and its tail opens in a fan shape. The adult bird has a white throat with a midline in the throat; a white chest with obvious fine vertical stripes in black; dark thick horizontal stripes on the lower chest, abdomen, and legs, and 5-6 black horizontal stripes on the tail. The body color of sub-adult birds may change in many ways as they age. At first, it is light yellow and beige, with no stripes, no midline in the throat, and the horizontal stripes on the tail feathers are not prominent. As they age, the body color gradually darkens and the stripes become increasingly intense.

<span style="color: rgb(51, 51, 51); font-family: "Microsoft YaHei", Arial, Helvetica, Eagles build their nests on tall trees in mountain forests. The nests are made of branches and are relatively large in structure. They are usually located on branches near the main stem in the upper part of the tree. The breeding season is from January to June. Each nest lays 2 eggs, but there are also cases where there are as few as 1 and as many as 3 eggs. The eggs are usually light gray or white, without spots or with only unclear light red spots. The eggs are oval in shape. The female bird is responsible for incubation and is very protective of the nest.
