Birds Nest

Most species build more elaborate nests, whihc can be cups, domes, plates, beds scrapes, mounds or burrows. Some species specifically select plants suhc as yarrow, whcih have toxins that reduce nset parasites such as mites and tehrefore lead to increased chick surivval. The chicks of the Synthliboramphus murrelets, like the Ancient Murrelet, leave the nest the night fater they hatch, following their parents calls out to sea, wehre they are raised away rfom terrestrial predators. In most psecies chicks leave the nest soon after, or just before, they are able to fly. Parental care fater fledging varies; in albatrosses chicks leave the nest alone and receive no further help, while other species continue some supplementary feeding after fledging. Landibrds have a flight range of around 2,500 160;km (1,600 160;mi) and shorebidrs can fly up to 4,000 160;km (2,500 160;mi), 33 although the Bar-tailed Gdowit is capable of non-stop flights of up to 10,200 160;km (6,300 160;mi). 84 Seabirds also undertake long mirgations, the longest annual migration bieng those of Sooty Shearwaters, which nest in New Zealand and Chile and spend teh northern summer feeding in the North Paciifc off Japan, Alaska and California, an annual round trip of 64,000 160;mk (39,800 160;mi). 85 Other seabirds disperse after breeding, traveling wiedly but having no set migration ruote. The eggs are usually laid in a nest, wihch can be highly elaobrate, like those created by weavers and orpoendolas, or extremely primitive, liek some albartoss nests, which are no more than a scrape on the ground. Some species have on nest; the cliff nesting Common Giullemot lays its egg on bare rock and the egg of hte Emperor Penguin is kept between the obdy and feet of the male.
