Rockhopper penguin Northern Rockhopper; and the "Eudyptes chrysocome", the Southern Rockhopper. They are separated by their locations of breeding. There are four other species in the genus "Eudyptes": "E. pachyrhynchus", "E. robustus", "E. chrysolophus", and "E. schlegeli". The three subspecies of the rockhopper penguin are believed to have split up because of latitude and watermasses rather than because of geographic distances. Research suggests that during the early Pleistocene, the Southern Ocean was cold and rockhopper populations from the Atlantic and Indian Oceans remained undifferentiated and lived in the same watermass. The mid-Pleistocene climatic transition was associated with the southward migration of frontal
Blue Bird Micro Bird of a passenger van to a school bus. In another departure from precedent, the MB-series buses utilized aluminum body panels in place of steel. The MB-II was offered with two different entry door configurations: a standard bus door (standard on Ford-chassis buses) and a van-style door (standard on Chevrolet/GMC G-van prior to 1997). In 2009, Girardin Minibus entered its second joint venture with Blue Bird. The partnership, named Micro Bird, Inc., consolidated all Type A school bus production at the Girardin facilities in Drummondville, Quebec, Canada. Under the agreement, Blue Bird shifted production of van-based buses to Girardin (to again
