White Wagtail(leucopsis), 10/26/2012

The pictures below are all black-backed White Wagtails, with the Scientific Name Motacilla alba leucopsis, belonging to the leucopsis subspecies under the main White Wagtail species with the Scientific Name Motacilla alba in general. This subspecies is mainly mixed black and white, quite unique in Taiwan. They like to hang around in the stinky gutters in search of foods. The food sources there must be very attractive to them. In fact, they also search foods in farm fields or grasslands. In Taiwan, most of them are wintering birds, but some are local birds which stay all year round.

There are many subspecies of White Wagtail in the world, all looking very much alike. In Taiwan, three subspecies have been spotted, i.e., the leucopsis, ocularis and lugens subspecies. Within these three subspecies, only the leucopsis subspecies bears no eyelines. The other two subspecies all bear eyelines.
