A reproductive system is basically designed to produce young. Rufous is a reddish to brownish-red color. A savanna is tropical or subtropical grassland. A plain covered with coarse grasses and a few scattered trees is a savanna. A scrape is a bare or rocky flat surface where some birds lay their eggs.
Birds nesting on a scrape typically use grass instead of sticks for their nests.
A snag can refer to a jagged and projecting stump or part of a tree. On a raptor, spicules are tiny spiked bumps found on the bottom of the bird's feet that have a sandpaper-like texture. A tamarack is the name of a specific pine tree. It is unusual because unlike other conifers, this tree has deciduous leaves. The tamarack is native to the northern parts of North America and grows in moist and boggy soil.
