Hummingbirds have got their name from the distinct “hum” sound made by their rapidly flapping (拍打) wings.The size of the bird decides the number of flaps it can do.The average lifetime of a hummingbird is 3 or 4 years, but some of them have lived beyond 12 years also.They are unique in many ways.Besides the number of rapid flaps they can do per second, they can also fly backwards.

Hummingbirds have an amazing sense of assessing the amount of sugar in the nectar (花蜜) they eat.They feed on the nectar of flowers.Hummingbirds do not feed on flowers whose nectar contains less than 10% sugar.Talk about a sweet tooth! As they cannot sustain themselves on nectar alone because of its poor nutritional value, they also feed on insects and spiders, and hummingbird food mixture that one can make at home.

Attracting hummingbirds to your garden will require a little planning.Plant butterfly bush, mimosa, coral bells, foxglove, morning glory, etc.These flowers attract the hummingbirds due to their high visibility (可见性) and nectar production.Avoid using pesticides (杀虫剂), as it will not only kill the insects around the flowers, but hurt the hummingbirds as well.

A common food for these birds is the sweettasting sugar syrup (糖浆).Hummingbird food ingredients are just two: sugar and water.Take a large clean bowl, pour in it four cups of hot water, and dissolve one cup of table sugar in it.Stir slowly until all sugar has dissolved.

Hummingbirds, tiny as they are, collect a lot of nutrition.Providing them with hummingbird food mixture made of sugar water is a sure way to get all these beauties humming in your garden.

  A.they can't find any green plants

From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go.This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy.Solar panels on the Eclectic's roof absorb sun rays when you're driving.On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked.The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged.Zipping (迅速行进) around the neighborhood has never been better.
