The area is also good for eastern specialities such as Isabelline Wheatear, and, at almost the most westerly points of their range, Red-fronted Serin and Krüper's Nuthatch.

The term is found in reference to plumage colouring in the bird species names Isabelline Waterhen, Isabelline Wheatear, and Isabelline Shrike, as well as in descriptions of birds.

The Isabelline Wheatear (Oenanthe isabellina) is a small passerine bird that was formerly classed as a member of the Thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae.
