One of the mysteries of the English language finally explained.
A large flightless bird of South American grasslands, resembling a small ostrich with grayish-brown plumage.
Family Rheidae: two species, Rhea americana and Pterocnemia pennata
- ‘In rheas, very small and very large clutches are more likely to be abandoned during incubation compared to intermediate-sized clutches.’
- ‘Because rheas walk almost continuously while foraging, we considered that they were walking instead of foraging only when the head was above the body while walking.’
- ‘Rheas were considered to be solitary when no other rheas were within a radius of 100 m, whereas they were considered to be part of a group if they were within 50 m from one another.’
- ‘The rhea and our very own ostrich, as well as the emu from New Zealand all look as if they had the same ancestor.’
- ‘Like other studies of rheas we also observed that the male incorporated to its group chicks from other groups.’
- ‘Likewise, if rheas and ostriches share a common ancestor, then the separation time of Africa and South America indicates that those birds have been evolving apart for 100-105 million years.’
- ‘Glacial ice in your whiskey, guaranteed guanaco, condor and rhea sightings, and even a vegetarian option come mealtimes are just some of the luxuries.’
- ‘The grass plains have long been home to the rhea, whose eggs are thought a delicacy, as well as the flesh, which is either jerked or eaten fresh.’
- ‘The park is home to 105 species of birds ranging from condors and austral parakeets to rheas - the South American ostriches.’
- ‘Located within the National Trust's beautiful Morden Hall Park, Dene City Farm has a wide variety of farm animals from the common chickens, pigs, cows to the more exotic, such as ferrets and rheas.’
- ‘But because it also keeps small collections of wallabies, emus and rheas, pressure group Zoo Check says the farm should come under strict zoo regulations.’
- ‘However, for rheas living in subtropical areas, nest attention could also avoid egg temperatures increasing up to lethal level for embryos.’
- ‘Aside from the salary he receives from the foundation, Carlinhos has a pet shop and a farm close to the city where he wants to retire to raise rheas and capybaras.’
- ‘Moreover, if ostriches and rheas are indeed related to each other, as some evidence seems to suggest, then they represent a historical connection across the South Atlantic between Africa and South America.’
- ‘The chicks have now been removed from the father - who, in the case of the rhea family, incubates the eggs and cares for the chicks.’
- ‘A similar synchronized pattern was found in large flocks of ostriches and greater rheas, but these studies did not manipulate neighbor distance nor did they control for group size.’
- ‘For six hours we speed through sensational country, looking out for dolphins in the Straits of Magellan, and rheas, South American ostriches, as we cross the Patagonian steppe.’
- ‘In summary, in rheas as well and in other ratites, the high energetic costs associated with incubation and post-hatching parental care would favor paternal care and a mating system that combines polyandry and polygyny.’
- ‘He saw the common rhea - an ostrichlike bird - living in Argentina.’
- ‘Here's one with the flightless birds over there, the rheas.’
Early 19th century: modern Latin (genus name), from the name of the Titan Rhea.
One of the Titans, wife of Cronus and mother of Zeus, Demeter, Poseidon, Hera, and Hades. Frightened of betrayal by their children, Cronus ate them; Rhea rescued Zeus from this fate by hiding him and giving Cronus a stone wrapped in blankets instead.
A satellite of Saturn, the fourteenth closest to the planet, discovered by Cassini in 1672, and having a diameter of 951 miles (1,530 km).
