The nival zone - up to 6300 m This zone is restricted to a few rocky ridges and scree slopes, between the lower protrusi- ons of the glaciers and the closed plant cover of the meadows at the upper alpine level. The few pioneers among the vascular plants belong to the genera Saussurea, Saxifraga, Stellaria and Potentilla. No breeding birds migrate to these altitudes in summer, as the food sources are too few and their production too meagre. The highest altitude for breeding is most probably at the transition from the alpine to the nival zone; no bird will breed above 5500 m. Candidates for highest-altitude breeders include Eremophila alpestris, Phoenicu- rus ochruros. Ph. erythro gaster, Tetraogallus himalayensis, T. tibetanus, and Lerwa lerwa. Swan (1962) mentioned a breeding record of Lenva lerwa at 19,000 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bonn, Zoologisches Forschungsinstitut und Museum Alexander Koenig
