These days, the calls of this bird are so common that they will compel you to take notice. Owing to the purple colour of the bird, despite its minuscule size, you can locate it hovering and sucking nectar from flowers. Female are very difficult to locate as they are not purple at all but olive colored.
I think I wrote a post on this beautiful bird long back. Its name is Red Wattled Lapwing. It gets this name from the blobs of red colored mass near its beak. In fact, this bird is very common here and if you happen to live near fields, barren lands and water bodies, you are most likely to encounter them.
They are always on alert. Any preying bird or animal, is bravely and aggressively taken upon. They can be heard making alarming calls even during the night. They are said to be foraging even during moonlit nights.
They lay eggs on the ground. Nest is nothing but a collection of few pebbles, grass pieces. The selection of pebbles is done very intelligently so as to camouflage the eggs. While one partner sits on the eggs to hatch, the other stays nearby to alert about any danger.
People in north India believed that if it makes nest on the elevated places, there are chances of rain ahead. If the best is at lower level, the weather is going to be dry weather.
