There is a discussion on the eland stripes somewhere, Klippies...if there were different subspecies they interbred LONG ago! 

Go wild for Wildlife and help to keep our Conservation Areas pure, natural and green.

Cool to see a larger herd!
Only one has distinct white stripes. As far as I remember, the stripes (or lack of stripes) are attributed to different subspecies or populationsOr is that with coat colour only?
But interesting to see different ones in the same herd!Three subspecies of Common Eland have been recognised, though their validity has been in dispute
Tragelaphus o. livingstonii (Sclater 1864; Livingstone's Eland): It is found in the Central Zambezian Miombo woodlands i.e. southcentral Africa (Angola, Zambia, Democratic Republic of the Congo, Zimbabwe, Mozambique and Malawi). Livingstone's Eland has a brown pelt with up to
twelve stripes.
Tragelaphus o. oryx (Pallas 1766; Cape Eland): This subspecies is found south of the Zambezi river (South Africa, Botswana and Namibia). The fur is tawny, and adults lose their stripes.
Tragelaphus o. pattersonianus (Lydekker 1906; East African Eland or Patterson's Eland): It is found in east Africa extending into the Somali arid areas, hence its common name. Its coat can have up to 12 stripes.
Tragelaphus o. oryx occurs throughout the larger part of South Africa, but the far northern Limpopo Province bordering Zimbabwe is regarded as a transitional zone between T. o. oryx and T. o. livingstonii or an area where they overlap. This argues the case that they should rather be described as ecotypes (in ecotypes, it is common for continuous, gradual geographic variation to impose analogous phenotypic and/or genetic variation; this
situation is called cline.).
