For each of the predators they have a different alarm call allowing the rest of the family to know from where to expect the danger. These mongooses have a mutualistic relationship, relationship in which both species benefitwith Hornbills.
Sabi Sabi Wild Facts: Dwarf Mongoose
Both species keep a lookout and warn each other of danger while feeding together. There was a study done on the different alarm calls of the dwarf mongoose. A researcher noticed a variance between the calls in different geographic areas and wanted to investigate if there was any reason for this.Safari Live : Dwarf Mongoose plays dead for a Hornbill this morning ( Funny ) March 27, 2018
Recordings of the various mongoose alarm calls related to particular predators in one region were played back to a group in a different geographic location. The new group recognised that there may be a threat but had no idea where the threat was coming from. The conclusion of the study was that the dwarf mongoose has different dialects according to geographic location.

Besides the Hornbill, the dwarf mongoose has a relationship with another bird, the Fork-tailed Drongo. They are hunted, too, particularly by numerous birds of prey. Younger males thus spend much of their time looking out for predators, thus reducing their own foraging budget. Dwarf mongoose live mainly in dry semideserts, often in very broken terrain these in Samburu National Reserve. Young males are constantly on the watch, as many predators hunt the little mongooses.

So, it is quite clever, to engage a good watchdog! In the semiarid thorn bush, basically all dwarf mongoose groups live with hornbills. These birds catch insects on the ground and that is much easier, when they follow the groups humming with activity, scratching, and digging most of their time. Many disturbed insects try to escape and are easy picking for the birds. A red-billed hornbill sifting the ground, looking for insects. These birds are very cautious to aerial predators and react on every move in the sky.
Thirteen of the 28 species in Africa are found in open woodlands and savanna and even in highly arid regions. The remaining 23 species are found in dense forests. Diet Hornbills are omnivorous with a range of diets - from several species solely being carnivorous to others wholly being frugivorous fruit eating. Their carnivorous diets consist of insects, lizards, frogs, small mammals as well as other birds.
Fascinatingly, all the savannah and prairieland species are carnivorous, whilst all the frugivorous species are forest dwellers. However, a number of Tockus species are forest dwellers yet primarily carnivorous insectivorous too. Hornbills that are forest dwellers are considered important seed dispersers. Hornbills cannot swallow food that has been caught at the tip of their beaks as they have a short tongue which cannot reach, thus they toss their food back into their throat with a jerk of the head.

Most hornbills gain all the moisture that they need from their food, and thus hardly ever drink water, with their food intake varying throughout the year depending on what is available. Breeding Sexual maturity of the smaller species is reached in one year, medium species in two years and the larger species in three to six years.
Hornbills are commonly monogamous breeders, with some species engaging in cooperative breeding.

They nest in natural cavities in trees, cliffs and even abandoned nests of woodpeckers and barbets that may be used in consecutive breeding seasons by the same pair. Up to six white eggs are laid. Before incubation the female of the Bucerotinae species begins to close the entrance to the nest cavity with a wall of mud, fruit pulp and droppings, occasionally assisted by the male.
Once the female is ready to lay her eggs, the entrance is still big enough for her to enter the nest, but as soon as the eggs are laid, she seals the remaining opening shut and remains inside with her eggs.
However, a small gap is left open for the male to transfer food to the female and to the chicks at a later stage. This behaviour is apparently to protect the nesting site from predators and rival hornbills. During the incubation phase, the female moults her flight feathers completely and simultaneously for the nest and to keep her chicks warm.
An average clutch size for the larger hornbill species is one or two eggs, but in the smaller species they lay up to eight eggs. When the mother and her chicks are too big to fit in the nest, the mother will break out and both parents will then feed the chicks.
In some species, the mother rebuilds the wall whereas in other species, the chicks themselves build the wall unaided. The young hatch out of sequence rather than all together as incubation begins when the first egg is laid. This species' co-operative breeding is the highest in any order of birds; helpers assist the male with retrieving food for the mother and chicks before she breaks out. The percentage of young which survive is dependent on the number of helpers and the amount of food available.
