小燕子,穿花衣。

家燕的体型小巧,树麻雀和它比起来都会显得大一些。

离得远,它们看起来黑黢黢的,下巴一撮儿红色很明显,离得近,在阳光的照射下,羽毛本身有色素沉淀,除此以外,羽毛的物理特质使得在一些角度看,因散射、干涉或衍射的产生出的结构色,复合呈现出五彩斑斓的蓝色。

照片中可以看到羽毛部分:从结构上分类看是正羽,从功能上分类是飞羽。

春季,燕子忙着筑巢抚育下一代,因此,它们会为了找寻建筑材料,多次往返很是辛苦。

马上它们就要多起来了~

How to Use Bitcoin?

n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”

Traders also expressed uncertainty about the situation with China Evergrande, as the indebted property company has not provided clarification about a key interest payment.In economic news, the Commerce Department reported an unexpected increase in U.S. new home sales in August.Crude oil prices climbed Friday and front-month WTI oil futures contracts saw gains for a fifth straight week amid tighter supplies.
