Bush vetch

Bush vetch (Vicia sepium) is common throughout the British Isles, growing in grassy places, as a garden weed and in hedges. It is a sprawling plant that covers other plants and twines its tendrils around them. 

There are around 150 species of vetch, and they include the highly cultivated Vicia faba, otherwise known as the broad bean. There is evidence that cultivated vetches were planted from Iron Age times. 

However, bush vetch is of no use to humans other than as fodder for animals. 

Bush vetch can climb up to 40 inches (100 cms) off the ground. Each leaf has five to nine pairs of leaflets and a branching tendril. The short-stalked flowerhead has up to six blooms, which appear from May to August. The sepals are joined to form a tube. The nectar is particularly attractive to bumblebees. The seeds form in pods which go black when the seeds are ripe.

Purple milk-vetch

Purple milk-vetch (Astragalus danicus) is found throughout Europe from the Alps to Russia, but in Britain it is mostly found on the eastern side of the country, from the Chilterns to Scotland. It is especially common in the Breckland area of Norfolk. 

The habitat of purple milk-vetch is chalk and limestone soils, and also sandy areas including dunes.

The “milk” element of the name comes from the old belief that eating the plant increased the milk yield of goats, although there is no real evidence to support this notion. The plant has no food value to humans.

Purple milk-vetch has upright stems and many leaflets that are covered with soft whitish hairs. The plant grows up to 14 inches (36 cms) high.

Several purplish flowers are carried on each stem, well above the leaves, the flowers looking at first sight like those of clover. Sepals are joined at the base in a tube covered with short blackish hairs. 

The plant flowers from May to July, after which seed pods form that contain six or seven seeds.

Greater kudu

The greater kudu (Tragelaphus strepsicerus) is the third largest species of antelope (after the Giant eland and Cape eland). It reaches up to 270 cms (9 feet) in length and 160 cms (5 feet) in height. Males are larger than females. 

It is identifiable from the conspicuous mane on the throat, neck and back, and the crosswise white stripes on its flanks.

Only the males have horns, which can be to 172 cms (6 feet) long. 

The greater kudu inhabits most of southern Africa south of the Zambezi, and eastern Africa as far north as Sudan and Ethiopia. It avoids open grasslands, preferring thickets, bush and open forests.

The greater kudu lives mostly in small groups of four or five individuals, although older males are sometimes solitary.

Gestation lasts about 210 to 240 days, with a single calf being born except on very rare occasions.

Aardwolf

The aardwolf (Proteles cristatus) is a mainly nocturnal carnivore that is native to the arid and rocky regions of southern and eastern Africa.

Its colouring is yellowish grey with dark crosswise stripes. The conspicuous mane of long hair stretches from the nape of the neck to reach over the back, continuing as a bushy tail.

The shape of the aardwolf is similar to that of the hyaena, but its skeleton is more slender and its skull more elongated. Whereas hyaenas have five digits on both fore and hind limbs, the aardwolf has only four digits on its hind feet.

Aardwolves have small teeth that are widely spaced, the molars being completely rudimentary. This relates to the nature of their diet, which is mainly insects (especially termites) and birds’ eggs.

Cats that don`t mind water

We all know that cats hate getting wet – or at least, that is true of most of them.

That is because a cat’s fur can easily become waterlogged, although the top layer is water-resistant to an extent. A cat that falls into water can drown very quickly if a heavy, waterlogged undercoat drags it under. 

A cat’s fur does not dry easily, and a cold skin caused by waterlogging can lead to hypothermia. 

However, that is not the case with the Van cat of Turkey, found in the region of Lake Van in the east of the country. This cat does not have an undercoat, but its fur is smooth and water-resistant. Van cats delight in taking a dip in water to cool down on a hot day. The same is true of several “big cats” such as lions, tigers and jaguars. 

There is also the “fishing cat” of Southeast Asia (see photo). This cat hunts in water, diving to catch fish and sometimes even attacking ducks from beneath the surface. 

Domestic cats can sometimes becoming acclimatized to water in moderation. This includes show cats that have to tolerate being washed in order to look their best. And there are even cats that enjoy playing with water – although I, speaking for myself, have yet to come across one!

Emerald tree boa

The emerald tree boa (Corallus caninus) lives in the Amazon rain forest of South America. It is perfectly adapted for life in the trees, being difficult to spot as it coils around a tree branch and blends into the foliage.

These snakes grow up to two metres (6.5 feet) in length. It has white markings along the back that also help with its camouflage, as these mimic shafts of sunlight playing on green leaves.

The emerald tree boa preys on birds and small mammals, which it catches by lunging outwards or downwards while firmly anchored to a branch by its tail. Its eyes have vertical pupils which help it to sense movement. It can also detect the heat given off by an animal, thanks to deep pits in the scales around its mouth. Long teeth enable it to get a firm grip on its prey.

Up to 15 young will be born each season. These are variously coloured in shades of red, orange or yellow, only acquiring their green coloration after one year.

Rhinoceros iguana

The rhinoceros iguana (Cyclura cornuta) is a native of the Caribbean, and in particular the islands of Hispaniola (Haiti and the Dominican Republic) and Puerto Rico.

It is a large animal, measuring up 1.2 metres (4 feet) in length. It is characterized by several enlarged raised scales on the snout that look like horns. Males are larger than females, with larger horns and crests.

Rhinoceros iguanas walk ponderously with the head held up, but can run at speed when threatened. It will also bite and thrash its tail to defend itself. It is highly territorial.

Food consists of leaves and fruits.

Females will lay anything from two to twenty eggs in a burrow, which will be closely guarded.

Habitat destruction is a threat to the species, as are predations from non-native animals including dogs, rats, pigs and mongooses.
