Caption: great potoo, Nyctibius grandis, is a near passerine bird, both the largest potoo species and the largest member of the order Caprimulgiformes (nightjars and allies). During the day it perches upright on a tree stump, and is very cryptic, resembling part of the stump; this is a camouflage using color and shape. Ceiba Tops Lodge, Amazon River, The Amazon, Rio Amazonas, in South America is the largest river by discharge volume of water in the world and according to most authorities, the second longest in length - Wikipedia; Amazon River rainforest, Peru, South America, PotooG48678czvs.jpg

endangered Kirtland's Warbler, Dendroica kirtlandii, one of the rarest members of the wood warbler (Parulidae) family. It nests in just a few counties in Michigan's northern Lower and Upper peninsulas, in Wisconsin and the province of Ontario and, currently, nowhere else on Earth. Its nests generally are concealed in mixed vegetation of grasses and shrubs below the living branches of five to 20 year old jack pine, Pinus banksiana, forests. North America; Canada; Central Canada {Central provinces}; Ontario; Point Pelee National Park, one of the best bird migration concentration spots in the world, animals; wildlife {undomesticated animals}; birds {avain, aves, bird}; warbler; Kirtland's Warbler, Dendroica kirtlandii, endangered species. The jack pine forest community provides the primary nesting habitat for the Kirtland's warbler. This forest species is adapted to dry land conditions and has been present on the sandy outwash plains of northern Michigan since the retreat of the Wisconsin ice sheet about 14,000 years ago. A narrow, band of jack pine habitat can be found across the north central states and the province of Ontario. The Kirtland's warbler has very restrictive habitat requirements. In addition to being ground nesters, Kirtland's warblers prefer jack pine stands over 80 acres in size. Those stands, which are most suitable for breeding, are characterized by having dense clumps of trees interspersed with numerous small, grassy openings, sedges, ferns, and low shrubs. The birds nest on the ground under the living branches of the small trees. Jack pine stands are used for nesting when trees are about five feet high or about five to eight years of age. Nesting continues in these stands until the lower branches of the trees start dying, or when the trees reach a height of 16 to 20 feet (about 16 to 20 years of age). A breeding pair of warblers usually requires about six to ten acres for their nesting territory, although as little as 1.5 acres may be adequate under optimal conditions. Nearly all nesting occurs in jack pine stands where the soil type is Grayling sand. This is an extremely well drained sandy soil with low humus and nutrient content. Water percolates through the sand so quickly that nests seldom are flooded during a rainstorm. This soil also supports the plant community required for nesting habitat. Fire always has been an important disturbance factor in the jack pine barrens. The young jack pines upon which the Kirtland's warbler depends grow after fire removes older trees and rejuvenates the forest. Heat from fire opens jack pine cones to release seeds. Fire also prepares the ground for the germination of the seeds. Historically, the jack pine barrens were maintained by naturally occurring wildfires that swept through the region. The jack pine held little value for the lumbermen who came in search of white pine. Once logging activity ended in the 1880's, the continuing forest fires helped increase the range of jack pine, which created more nesting habitat. As a result, the Kirtland's warbler populat

Bangkok Chao Phraya River delta, Bangkok  is the capital and most populous city of the Kingdom of Thailand. It is known in Thai as Krung Thep Maha Nakhon or simply Krung Thep. The city occupies 1,568.7 square kilometres (605.7 sq mi) in the Chao Phraya River delta in Central Thailand, and has a population of over 8 million, or 12.6 percent of the country's population. Over 14 million people (22.2 percent) lived within the surrounding Bangkok Metropolitan Region at the 2010 census, making Bangkok an extreme primate city, significantly dwarfing Thailand's other urban centres in terms of importance. Limited roads, despite an extensive expressway network, together with substantial private car usage, have led to chronic and crippling traffic congestion, which caused severe air pollution in the 1990s. The city has since turned to public transport in an attempt to solve this major problem. Thailand, Asia; Pacific Rim; THAI48119_130.jpg
