[Q]: Article: This site , all-birds. com, is about bird watching. Enjoy your browsing. There is much to learn and see. Bird Watching Equipment Some items that might make bird watching more enjoyable are binoculars ( ) , a camera, some kind of system for keeping notes, and maybe a back pack. Birders often keep lists of the birds they see along with notes about the habits. There is some great bird log software that will let you keep records on your computer. For more details on choosing binoculars see our Binocular -Optics page. Clothes If you are walking through a wooded area just wear clothes you would wear on any hike or field trip. You are best off wearing clothes with dull colors that mix into the background. Greens, browns, and grays are good. Avoid fabrics that rustle easily. Depending on the birds you are watching you may want to get rain gear, rubber boots and warm clothing. For birds such as owls that you might look for in the evening a strong flashlight is also handy. Choosing a Bird Field Guide Take a good field guide to identify birds. Look for clear color pictures that make it easy to recognize one bird from another. Next to each picture should be detailed descriptions of each bird's anatomy, habits, and what it eats. The guide should have information about what habitat each species uses. Many guides have maps showing the range of different birds along with their migration patterns. Where and When to see Birds Learning the habitats of birds in your area will increase the number of birds you see, and make your birding more enjoyable. If you know that Meadow larks are likely to be in open grassy areas, and dippers are forage along stream beds, you may be looking for them if you are in those types of habitats. Edge areas where different types of habitats meet will likely have more species in them. You are more likely to see specific birds at certain times of the day. For example songbirds are easier to see two to three hours after dawn, or just before sunset. This is when songbirds are most actively feeding. Many small birds will be silent or even hidden during the rest of the day. After sunup is the best time to see eagles and hawks. Visibility is best for hunting at this time, and they can soar on the thermal currents from the warmed air. Birds like owls are more likely to be seen in the evening. Many shorebirds and waders rest at high tide and feed when the water rises or falls. Photographing Birds Patience in Bird Photography Most birds are afraid of people, and all species have their own comfort zone. With a little time you can learn the comfort zone of the birds you are photographing. Once they know that you are not a threat you may be able to get closer. Type or Style Your reason for photographing birds may determine your style and the kind of equipment you use. If you are just recording the kinds of birds you see you don't need to get as close, and you can use less expensive equipment, then you need for high quality prints. Photographing Birds in Flight Photographing birds in flight can be fun. Many digital cameras have a tracking function. With these you focus on the bird, and then as you track it the lens will keep focus. Use Your Yard Choose an open area where the birds will get direct sunlight, showing off their magnificent colors. Try using props Birds will often land on a stick or post near a seed feeder before going to the feeder. The background was just an out of focus fence but you can use anything you want for a background, and then wait for a bird to perch.

[Q]: Article: Thailand's capital Bangkok is both attractive and wonderful, a city of glass towers and concrete buildings crowded with nearly 10 million people. The ground beneath is spongy and moist. Imagine a brick resting on top of a birthday cake. That's Bangkok-and it's sinking into the Earth at an alarming rate. Thailand's disaster specialists have been warning of this coming disaster for years. One expert has said he's worried about Bangkok resembling Atlantis. Another previously told Global post that the city will be under five feet of water by 2030. The latest estimates suggest that Bangkok is now sinking as fast as two centimeters per year in parts of the city. The predictions for 2100 are even more terrible. By then , Bangkok will be fully submerged and unlivable. Like global warming, which will accelerate the city's submersion by raising the sea leavel, Bangkok's sinking problems are repeatedly _ But the monsoon season, currently underway, tends to bring this crisis to mind. A nasty storm can suddenly turn Bangkok's streets into gushing streams. Sewers overflow, taxis move through dirty water and, occasionally, kids can pick up displaced fish. Anond Snidvongs, director of the Southeast Asia Regional Research Center, predicts the city's outskirts will be the first to go. Parts of the shoreline ebyong Bangkok are already liend with pumps that make noises and help to transform invading seawater. They don't always work. During heavy rains, salt water flows in the streets of the city. Bangkok is swallowed up a little more each day. Experts tend to offer two solutions. The first is to pu up a massive seawall that could cost nearly $3 billion-nearly 1 percent of Thailand's current GDP. The second option is to give up entirely and move the capital to higher ground.
Question: Why is Bangkok sinking into the earth?
Options: (A) Its buildings are too heavy. (B) It has an overlarge population. (C) Its underground is too loose. (D) It is resting on top of a lake.
