In fact, excessive water can kill many species. In a severe drought, some species, such as E. microtheca can lose their leaves and appear to be dead after a long dry period, only to recover and turn into a compact, healthy-looking shrub after a deep watering. Most also grow in nutrient-poor soil, and fertiliser is rarely needed or beneficial.
[30] [33] Emus predominantly travel in pairs, and while they can form large flocks, this is an atypical social behaviour that arises from the common need to move towards a new food source. [33] Emus have been shown to travel long distances to reach abundant feeding areas.
Emus are soft-feathered, brown, flightless birds with long necks and legs, and can reach up to 1.9 metres (6.2 ft) in height. Emus can travel great distances, and when necessary can sprint at 48 kilometres per hour (30 mph); they forage for a variety of plants and insects, but have been known to go for weeks without eating.
The runaway emus, named Thelma and Louise, escaped from their home in Loris, a city about 100 miles northeast of Charleston about three months ago, owner Sam Morace told CBS News on Friday. Thelma ...
Two large emus on the loose in South Carolina ruffled the feathers of locals a week after dozens of monkeys escaped from a research facility in the Palmetto State.
But if the emus were that easy to catch they would be home already." The large, flightless creatures are the second-largest living bird, with an average height of more than 5 1/2 feet.
Many of the larger ratite birds have extremely long legs and the largest living bird, the ostrich, can run at speeds over 35 mph (60 km/h). Emus have long, strong legs and can run up to 30 mph (48 km/h). Cassowaries and rheas show a similar likeness in agility and some extinct forms may have reached speeds of 45 mph (75 km/h).
