The rock thrushes are medium-sized mostly insectivorous or omnivorous birds in the genus Monticola in the thrush family Turdidae. Three of the species are sometimes treated in a separate genus Pseudocossyphus.
All are Old World species associated with mountainous regions:
Forest Rock Thrush, Monticola (Pseudocossyphus) sharpei
Benson's Rock Thrush, Monticola (Pseudocossyphus) bensoni
Littoral Rock Thrush, Monticola (Pseudocossyphus) imerinus
Cape Rock Thrush, Monticola rupestris
Sentinel Rock Thrush, Monticola explorator
Short-toed Rock Thrush, Monticola brevipes
Miombo Rock Thrush, Monticola angolensis
Rufous-tailed Rock Thrush, Monticola saxatilis
Little Rock Thrush, Monticola rufocinereus
Blue-capped Rock Thrush, Monticola cinclorhynchus
White-throated Rock Thrush, Monticola gularis
Chestnut-bellied Rock Thrush, Monticola rufiventris
Technical Abstract: Accessions of the grape species Vitis monticola have been reported to be resistant to a root-knot nematode, Meloidogyne incognita, with resistance conditioned by a single dominant allele.
Vitis monticola accession DVIT 1376 is heterozygous for resistance to N avirulent M. incognita.
Vitis monticola is a source of nematode resistance, but accession DVIT 1376 does not offer resistance superior to that available in contemporary grape rootstock varieties.
Forma monticola is a tree or spreading shrub with tortuous branches, if a tree, then to 10 m with crown flattened to broadly conic.
The bark is 5-10 mm thick, gray to gray-brown, exfoliating in fibrous, longitudinal strips.
Forma monticola: Widespread in rocky subalpine (above treeline on Nevado de Colima, Jalisco) oak-juniper, Pinus or Abies forests, as an understory shrub or small tree, at 2,400 to 4,300 m elevation.
