Thai hornbills supported by UK charity

Money donated by Colchester Zoo's charity Action for the Wild supports vital conservation research for three hornbill families in Thailand
June 2012. In 2011, Colchester Zoo's charity Action for the Wild sponsored families of rhinoceros, wreathed and great hornbill species which all nest around the Budo Mountain area, part of the Budo-Sungai Padu National Park in Thailand.
Chicks
In 2011, the wreathed hornbill family were successful in fledging a chick meaning that this family have been very successful having fledged 9 chicks since 1999. The new great hornbill family were also successful in fledging a chick during 2011 resulting in this family having another successful breeding year bringing the total to 12 fledged chicks since 1994. It was noted that both of these families had similar nesting diets made up of almost entirely fruits mainly of fig species.
Rhinoceros hornbill
The rhinoceros hornbill family also successfully fledged one chick during their nesting season however, their diet throughout the nesting period was different as although they ate mainly fruits they were not of the fig species. This family have produced at least 7 chicks since 2000. Some data collection by the team during 2011 was incomplete for some of the other family groups they monitor due to poor weather conditions and incidents of unrest in Thailand's southernmost provinces, and so workings in unsafe areas had to pause.
The Hornbill Family Adoption Program will still carry on for 2012, with the project continuing to monitor our hornbill families. The team will also continue to promote hornbill conservation and train villagers as nature guides, so they can earn an income in a more sustainable way.

Colchester Zoo's charity Action for the Wild has been supporting the Hornbill Research Foundation since 2002 annually donating $450 to support three hornbill families in Thailand.

Africa: warthog befriends hornbill for grooming favour

Friday, 26 February 2010

A warthog has been pictured being groomed by a huge bird known as a ground hornbill.

The warthog approached the southern ground hornbill seeking the favour, and the bird obliged by removing parasites from the warthog's body.

Similar interactions occur between warthogs and other animals such as banded mongooses.

But hornbills are not known to groom in this way, say scientists who photographed the incident.

Details of the behaviour are reported in the African Journal of Ecology.

"The warthogs approached the hornbills and then lay down on their sides to be cleaned," explains Dr Hendri Coetzee of North West University, Potchefstroom, South Africa.

"The warthogs were very nervous, because this behaviour most probably makes them more vulnerable to predation."

Opposites attract

Dr Coetzee says he repeatedly observed similar interactions between common warthogs (Phacochoerus africanus) and southern ground hornbills (Bucorvus leadbeateri) in the Mabula Game Reserve in South Africa's Limpopo Province.

The arrangement is mutually beneficial: the warthog gets a cleaning service and the ground hornbill a nutritious and easily obtainable food source.

Other animals will also groom warthogs, picking off parasites from the wild pig's body.

For example, banded mongooses remove ticks from warthogs, in what is believed by scientists to be the only symbiotic relationship between two mammal species.

Oxpecker birds also regularly clean the skins of a number of African mammals, including zebra and hippos.

But the interactions with the hornbills stood out because the warthogs usually initiated the grooming.

Southern ground hornbills are large black plumaged birds, with powerful beaks that can kill tortoises and large snakes.

"What surprised me was how delicately they were removing parasites from the warthogs," says Dr Coetzee.

"Adult warthogs even tolerated the ground hornbills probing their ears and around their more delicate areas under their tails."

Dr Coetzee speculates that the animals might be behaving this way in part because they are living on a game reserve, where they might be less threatened and more relaxed.

"It is most likely the result of learned behaviour and regular contact between the same individuals living under somewhat artificial circumstances, where the risk of predation is reduced," he explains.
