Invasion of Abyssinian Gras Rats

I observed this ‘small’ mass occurrence of gras rats in Northern Ethiopia. The species is perhaps Abyssinian grass rat (Arvicanthis abyssinicus), they have a small black stripe on the back. They emerged on a plateau, which is covered with fields and surrounded by stony slopes. They emerged on a plateau, which is covered with fields and about 2200 m above sea level. From one day to the other hundreds of specimens were observed in small groups, which were distributed over the fields or occurred along a river.
