Keepers at ZSL London Zoo have welcomed the arrival of a critically endangered baby monkey.

The three-week-old Sulawesi crested macaque was born to 17-year-old Winoo after a gestation period of 174 days.

Yet to be named, the infant is expected to triple his weight before the end of 2016. He will be nursed by his mother for another six months, before moving on to a diet of leaves, fruit and insects. (Image: ZSL London Zoo)

The One Live concert, hosted by Professor Noel Fitzpatrick, will return on Saturday, 4 June this year. The music festival is held in support of the Humanimal Trust and aims to raise awareness of one medicine.

Prof Fitzpatrick says: "I truly believe that ONE MEDICINE is the only rational solution to finding cures for diseases like cancer and the only rational thought process to look after all animals too, both domestic and wild, in our ever shrinking planet. I have committed my entire life and everything I stand for to this goal. The future of our children and the planet they inherit depends on what we do right now."

This year's line up consists of headliners Reef, who will be joined at Loseley Park by The Feeling, Scouting for Girls, Sound of the Sirens and Sunshine Underground. The concert will start at 6.30pm. Tickets are available from Ticketmaster: ticketmaster.co.uk/event/3500504999C64EC2

Researchers at the University of Glasgow's MRC Centre for Virus Research have been awarded a £300,000 grant to study the Zika virus alongside a research centre at the Oswaldo Cruz Foundation in Brazil.

Zika has been declared a global emergency by the World Health Organisation. It has spread to more than 20 countries in Central and South America and has been linked with microcephaly (abnormal smallness of the head) in newborns.

The research teams will study the presence and epidemiology of the virus in Brazil and hope to improve understanding of how the immune system responds to infection. Their work will be used to support vaccine development studies.

A new awareness day has been launched to help find out the frequency of laminitis in Britain, as well as possible prevention methods. Horse owners are being asked to share data about this debilitating condition as part of National CARE Month (10 February).

The CARE study is being carried out at the Animal Health Trust and Royal Veterinary College. To date, it is the largest web-based project of its kind. So far, it has 1,500 members who are asked to submit regular information about their horse or pony's health and management.

A further 1,000 members are needed for the study. Participation is open to all types, ages, sizes and breeds of horse or pony, whether they have had laminitis or not. See www.careaboutlaminitis.org.uk for more information.

Figures released by the RSPCA show that the number of cruelty and neglect calls recieved about exotic pets has increased by a staggering 50 per cent in just seven years.

In 2015 the charity investigated 2,772 calls received about reptiles, including bearded dragons, corn snakes, royal pythons, terrapins and leopard geckos. The figure is a huge rise from the figure of 1,840 reported in 2008.

Experts believe the issue stems from the sale of exotic pets on the internet as in many cases owners are not advised on how to care for their animals.

The British Hen Welfare Trust has set a new world record by rehoming its 500,000th hen.

Affectionately named 'Dee', because 'D' represents 500 in Roman numerals, the hen was taken from a commercial egg farm in the West Midlands and adopted by the Elliot family from Rugby.

Julie Elliott and her daughter Rosie (aged five) remarked that re-homing the charity's 500,000th hen would be a day they would always remember.

Julie commented: "She is beautiful and such a sweet girl, we had completely fallen in love with her long before we even got her home."
