Hummingbird Plants thrive in any condition

Hummingbirds are birds that comprise the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5���13 cm (3���5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm Bee Hummingbird. They hover in mid-air by rapidly flapping their wings 12���80 times per second (depending on the species). They are known as hummingbirds because of the humming sound created by their beating wings, which sometimes sounds like bees or other insects. A group of hummingbirds is called a "choir." To conserve energy while they sleep or when food is scarce, they have the ability to go into a hibernation-like state (torpor) where their metabolic rate is slowed to 1/15th of its normal rate.[1] When the nights get colder, their body temperature can drop significantly and thus slow down their heart and breathing rate, thus burning much less energy overnight. As the day heats back up, the hummingbird's body temperature will come back up and they resume their normal activity. [2] They can fly at speeds exceeding 15 m/s (54 km/h; 34 mph);[3] they are also the only group of birds with the ability to fly backwards.[4]Individuals from some species of hummingbirds weigh less than a penny.
WASHINGTON A majority of Americans think President Obama should be voted out of office next year, according to a new Associated Press-GfK poll.The poll contained troubling signs for the incumbent as he prepares for a grueling reelection campaign. While Americans were evenly divided on whether they expect the president to earn a second term, most of those polled said he does not deserve one.For the first time, the poll found that a majority of adults, 52 percent, said Obama should be voted out of office while 43 percent said he deserves another termObama's overall job approval stands at a new low: 44 percent approve while 54 percent disapprove. The president's standing among independents is worse: 38 percent approve while 59 percent disapprove. Among Democrats, the president holds steady with an approval rating of 78 percent while only 12 percent of Republicans approve of the job he's doing.Obama's overall poll numbers suggest he is in jeopardy of losing, even
electronic countermeasure system intended to jam airborne radar systems.Reports suggest that these 1L222 Avtobaza detectors were used to jam communications with the drone.Stephen Trimble, a military analyst for aviation website Flight Global, called the Avtobaza "the perfect tool to target and perhaps infiltrate the communications link that allows a UAV to be controlled from a remote location.""Since we know the Iranians now have the Avtobaza, it seems that the system is at least the basis of Iran's claims that the RQ-170 was captured by way of electronic subterfuge," Trimble told FoxNews.com. A former U.S. ambassador said earlier in the month that if such reports are true, the situation becomes all that much worse."Some reports have said Russia sold (Iran) a very sophisticated jamming system a short time ago," U.S. Ambassador to the United Nations John Bolton told Fox News. "Now, our military says that is not true, it came down because of a malfunction. I certa
