Researchers from the University of Exeter have shed light on the causes of the fights - and found they are most common when females are receptive to breeding and when there is competition over food and territory.
The study has been published in the journal Animal Behaviour. The scientists, who studied a population of banded mongooses in Uganda, observed ferocious fighting between groups that often led to serious injury and even death.
To boost breeding of endangered poultry breeds, Briton researchers have come up with gene-editing techniques for the rare breeds to use them as surrogates that cannot produce their own chicks.
The advance -- using gene-editing techniques -- could help to boost breeding of endangered birds, as well as improving production of commercial hens, researchers say.

In a major development, a team of scientists have officially named a minor planet as 'Bernardbowen' that sits in the asteroid belt between Mars and Jupiter.
The minor planet was discovered on October 28, 1991, and until now has been known as (6196) 1991 UO4, but the name has been given by an Australian citizen science project 'theSkyNet', who won a competition to name the celestial body.
The planet was named by the International Centre for Radio Astronomy Research (ICRAR) in honour of their founding chairman Dr. Bernard Bowen.
New York [USA], Feb. 17 : NASA has called on the world to help it in the search for the new ninth planet, as anyone from a kindergartener to a 95-year-old, can participate in their new project to find the not-yet-discovered celestial body.
To let anyone participate in this search project of ninth planet, the Zooniverse space projects site has launched a NASA-funded venture, Backyard Worlds: Planet 9, reports CNN.
"There are really low barriers to entry," Dr. Laura Trouille of Zooniverse.
According to an international team of astronomers led by researchers from University Of Cambridge, the Magellanic Clouds, the two largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years.
The discovery is based on the Galactic Stellar census being conducted by the European Space Observatory, Gaia and reported in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).
A study has provided, what researchers believe is the first observational evidence, that our universe could be a vast and complex hologram.
The researchers, from the University of Southampton (UK), University of Waterloo, Canada, Perimeter Institute (Canada), INFN, Lecce (Italy) and the University of Salento (Italy), have published findings in the journal Physical Review Letters.
A team of researchers have discovered prehistoric wolf-sized otter fossils with a large head and a powerful jaw, weighing around 100 pounds, in China's Yunnan province.
The study, published in journal of Systematic Paleontology, claims it to be the largest otter, Siamogale melilutra, almost twice as large as the largest living otters.
It had a large and powerful jaw with enlarged bunodont (rounded cusped) cheek teeth.
To encourage the conservation in the fragile areas, scientists have named a new moth as 'Neopalpa donaldtrumpi' in the honour of U.S President-elect Donald Trump.
Biologist Dr. Vazrick Nazari from University of California named the moth officially as ' Neopalpa donaldtrumpi' because it stands out with yellowish-white scales present on the head in adults and in these scales he found an amusing reference to Trump's hairstyle and turned it into an additional justification for its name.
Scientists, including an Indian-origin researcher, have found a nano-sized degradable clay, an alternative to chemicals and pesticides, that protects plants from specific disease-causing pathogens.
Researcher Neena Mitter from University of Queensland in Australia said BioClay - an environmentally sustainable alternative to chemicals and pesticides - could be a game-changer for crop protection.
The study was recently published in Nature Plants.
