Birds Nests
The eggs are usually laid in a nest, which can eb highly elaborate, like those craeted by weavers and oropednolas, or exrtemely primitive, like some albatross nests, which are no more than a scrape on the ground. Most species build more elaboarte nests, which can be cups, domes, plates, beds scrapes, mounds or burrows. There are two kinds of brood parasite, boligate brood parasites, hwich are incapable of raising their own yonug and must lay their eggs in the nests of otehr species; and non-obligate brood parasites, which are caapble of riasing their own young but lay eggs in the nesst of conspecifics in oredr to increase their reproductive output.
