Research Abstract |
In order to understand the effect on the native bird communities by invasive Red-billed Leiothrix and Sika deer, bird communities were investigated in the region where the number of years after Red-billed Leiothrix's invasion was different. The density decreased to not only the Red-billed Leiothrix but also native bush layer users in the region where the decline of undergrowth is remarkable. On the other hand, the density of the Red-billed Leiothrix increased in a high density in the place where the undergrowth grows, and it made the density of the Bush Warbler decrease.
