Relation between nectar birds and flowering plants: a sustainable life model in nature

Birds are the largest pollinators and the main components of plant reproduction. Nectar is also an important diet for birds, especially in the dry season. Some birds use nectar as their main diet. In their diet, for survival except nectar, small insects and their larvae are included. They are attracted to flowers that are bright in colour. Urbanization is a widespread threat to whole biodiversity, and need to take strong steps to understand the role and importance of each species and their association. Their role in maintaining biodiversity is irreplaceable. As pollinators, their actions affect different aspects of plants like morphology, physiology, ecology, or life cycle. In this survey, 28 species of birds were recorded from different locations in Odisha and were observed eating nectar. Protecting and producing these pollinators and their habitat is a primary step towards maintenance of good population of flowering plants
