Common Myna (Acridotheres tristis), the most abundant avian omnivore in the Indian Peninsula has a diverse food habit of consuming natural as well as human left over (HLO) foods. However, they have evolved a foraging optimization strategy of consuming nectar of Palash (Butea monosperma) from late winter to spring as primary food and other food types as secondary. Such food shifting did not alter their Protein - Lipid - Carbohydrate requirement. The study also reveals that birds have evolved strategies to identify better nectar variant of Butea monosperma plants and concentrate on those plants only while neglecting the less profitable one. Seasonal body weight comparison in humanized and natural habitat also correlates with their food choice. From the aforesaid observations it can be assumed that feeding optimization of Common Myna has definite link to its pre-breeding season preparation.
