Rank : 2
Summer Visitor

Although not as commonly known as Barn Swallow, Asian House-Martin is a common summer visitor to spend breeding period here. At first glance, the bird resembles Barn Swallow, but, with shallow forked tail, Asian House-Martin looks a bit dumpy; white rump and underparts are conspicuous in flight. In Asakawa River basin, it comes over a bit later and leaves a bit earlier than Barn Swallow here. Nests colonially under bridges and elevated structures; big colonies are usually found at the Ichiban Bridge, Ohwada Bridge, and Asakawa Bridge as well as at the Hachioji Railroad Station and Takaosanguchi Station, but the colonies are not permanent and vary from year to year.
