African crakeとは 意味・読み方・使い方

The African Crake (Crex egregia) is a bird in the rail family that breeds in most of sub-Saharan Africa away from the arid south and southwest. It is seasonally common in most of its range other than the rainforests and areas that have low annual rainfall. This crake is a partial migrant, moving away from the equator as soon as the rains provide sufficient grass cover to allow it to breed elsewhere. There have been a few records of vagrant birds reaching Atlantic islands. This species nests in a wide variety of grassland types, and agricultural land with tall crops may also be used.
