and Canada gradually boosted trumpeter swan populations. We are interested in the process of local adaptation, particularly in response to seasonal variability. Shredder: Birds of prey like hawks and owls have sharp, curved bills for tearing meat. Although a frog has teeth and a tongue like humans do, they use their teeth to keep the victim in the mouth and not for chewing. Cassowaries swallow fruit whole, digesting the pulp, and passing the seeds unharmed in large piles of dung, distributing them over large areas throughout the rainforest. Violet-green Swallows are often found at forest edges with large snags or other cavities for nesting. This is any inheritable trait that increases it’s survival rate so that it can live longer, reproduce longer, and have more offspring (that also have that trait). Description.

Epiphytes are non-parasitic plants that grow on other plants, getting their nourishment from the air. Bird flight is extremely complex, involving intricate interactions among nerves, muscles, tendons, skeleton, feathers, and metabolism. Nesting Sites: Many types of swallows, swifts, and martins are cavity-nesting birds, and they will readily nest in birdhouses or specialized gourds.
