不知是什么时候,在小区车库的檐下,两只燕子就着一根电线和固定电线的闸盒,在墙上筑起了小巢,窝的上方有二楼平台掩着,下雨浇不着。小小燕巢两角向上,中间低凹,像个泥做的兜兜,细细的草茎掺和在其中,还挺结实的。两个小家伙居然在都市楼林的水泥墙面上筑窝,也真是难为它们了。 I do not know when, in the garage of the community, two swallows with a wire and fixed wire brake box, built a small nest on the wall, the top of the nest there is a second floor platform to cover, it’s raining . The small swallow nest has two corners up and the middle is concave, like a mud-carrying pocket. The thin grass stems are mixed in and it is quite strong. It is really hard for the two little guys to build nests on the concrete walls of the urban buildings.
