In both cases, the swallows hunt insects in flight, with the house swallow preferring to fly low in villages and urban margins, while the golden-loined swallow prefers to fly in the suburbs of cities with large undulating terrain and the mountainous hills of the countryside. The two swallows are similar in size and size, and if you don't pay attention to distinguish them, you will definitely think that they are a bird, in fact, they are different bird species with reproductive isolation.
In addition to these two kinds of small swallows, there is also a kind of swallow called Lou Yan'er, Beijing Qianmen Lou has a lot, and the first two kinds of swallows that belong to songbirds in classification, this swallow is a climbing bird, their most obvious difference, the four toes of the house swallow and the golden-waisted swallow are the first three and the last one, so that they can grasp the branches, wires, etc. to inhabit the upper side, can also fall to the ground activity; and the four toes of the Lou Swallow are all facing forward, so that they can not grasp the branches and wires to land on the top of the perch, nor can they fall to the ground to move, You can only fly non-stop in the sky, tired can only hang like a bat with your toes to hang in the cracks in the wall and rest, so this swallow is also commonly known as "footless swallow". In addition, Lou Yan would not whisper softly like Jia Yan and Jin Waist Yan, but would only make a hissing sound. Lou Yan is actually a kind of Swift, Beijing's environmentalists specially set up camera tools at the front door and other places, live broadcast Lou Yan's flight activities in real time, the name of the live broadcast is called "Swift is coming", if you go to Beijing, do not miss the opportunity to observe Swift.
