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～

Export WhatsApp stickers to Telegram on iPhone

You can’t. What you can do, though, is use WhatsApp’s and Telegram’s web platforms to transfer stickers. It’s easy, but might take a while.Open WhatsApp in your browser, find a sticker you like in a chat, and right-click on it to save it as an image. The file won’t be a picture, though—it’s a webpage and will have a .webp extension. Don’t be scared, this is the way. Repeat this step to save as many stickers as you want.Then, open Telegram in your browser and go into your Saved messages chat. Just as you’d share a file with a friend, click the Share file button on the bottom left of the chat window (it looks like a dog-eared paper), and select the .webp files you downloaded. Click Open and you’ll see your stickers in your Saved messages chat. This is now your sticker depository. To use them, forward them as you would a message from one chat to the other: by clicking or long-pressing on the sticker, and then choosing Forward.
