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~

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
