Comparison of Adaptations for Nectar Feeding in Hummingbirds and American Leaf-Nosed Bats

Co-evolution of flower plants and their pollinators mediates various life forms on the earth. 250,000 plants, pollen vector of most animals including at least 1,200 vertebrates. Most tropical and subtropical plants are pollinated by insects and a small number of ecologically and economically important plants are pollinated by birds and mammals (Devy and Davidar, 2003). Bats and birds have honey fed families in their order and these two groups have developed similar features for this ecological position.

The bat that eats honey got a special adaptability. These bats have a long zzles mouth and a long, elasticized tongue covered with thin bristles that help them feed on certain flowers and plants. Anoura fistulata has the longest tongue among all mammals compared to its size. This is good for them in terms of pollination and feeding. Their long narrow tongue can penetrate into the long cup shape of some flowers. When the tongue is retracted, it winds up inside the ribs. Because of these features, bats that eat nectar can not easily switch to other food sources when they are missing and disappear more than other kinds of bats. Since pollen adheres to those furs at feeding time, these bats act as pollinators, so honey feeding also contributes to various plants. About 500 flower plants depend on bat pollination, so flowers tend to bloom at night. Many tropical rainforest plants rely on pollinating bats

The main night-time pollinator is a small long nose bat that is eating honey. Many flower features are suitable for bat pollination: opening of flowers at night, aging of pollen at night, location on the ground, durable flowers, weight of bats, and a night scent. In addition, the amino acids in the pollen seem to help maintain bat nursing. Aboriginal birds such as Gila Woodpecker, Purple Martin, House Finch, Gilded Glitter live in the cave of Segueiros. Flicker dug a big hole in the pole. The nest is deep, and parents and young people are completely hidden from view. Saguaro makes callus for wounds. Even though Sagaro dies and its soft meat rots, the callus is still so-called Sagaro boots, the locals use it to preserve it.

As most people know, hummingbirds eat charming "gifts" of high energy sugars offered by flowers in exchange for pollination. Hummingbirds consume huge amounts of small insects and their larvae, rich in high energy fat and essential proteins, in addition to honey and sap. Hummingbirds have a greedy appetite for their huge metabolic needs. Because hummingbirds eat twice a day, it is three times the amount of honey, the amount of sap, insect weight.
