Common tsessebe - Wikipedia. The common tsessebe or sassaby (Damaliscus lunatus lunatus) is one of five subspecies of African antelope. Damaliscus lunatus of the genus Damaliscus and subfamily Alcelaphinae in the family. Bovidae. It is most closely related to the topi, korrigum, coastal topi and tiang (all subspecies of Damaliscus lunatus), and the bangweulu tsessebe and bontebok in the same genus. Red clover is a short-lived perennial that is winter hardy throughout Pennsylvania. Red clover can be used as a cover crop that provides many benefits such as fixing. The common tsessebe or sassaby (Damaliscus lunatus lunatus) is one of five subspecies of African antelope Damaliscus lunatus of the genus Damaliscus and subfamily. A duiker / The Duiker gets its name from the Afrikaans word 'duiker' which means to dive, relating to the animal's habit of ducking away into bushes when danger. Tsessebe are found primarily in Angola, Zambia, Namibia, Botswana, Zimbabwe, Swaziland, and South Africa. For males, horn size plays an important role in territory defense and mate attraction, although horn size is not positively correlated with territorial factors of mate selection. The fronts of their faces and their tail tufts are black; the forelimbs and thigh are greyish or bluish- black. Their hindlimbs are brownish- yellow to yellow and their bellies are white. Females form herds composed of six to 1. After males turn one year of age, they are ejected from the herd and form bachelor herds that can be as large as 3. Territorial adult bulls form herds the same size as young bulls, although the formation of adult bull herds is mainly seen in the formation of a lek. Territorial behavior includes moving in erect posture, high- stepping, defecating in a crouch stance, ground- horning, mudpacking, shoulder- wiping, and grunting. The most important aggressive display of territorial dominance is in the horning of the ground. Another far more curious form of territory marking is through the anointing of their foreheads and horns with secretions from glands near their eyes. Tsessebe accomplish this by inserting grass stems into their preorbital glands to coat them with secretion, then waving it around, letting the secretions fall onto their heads and horns. This process is not as commonly seen as ground- horning, nor is its purpose as well known. One such behavior is the habit of sleeping tsessebe to rest their mouths on the ground with their horns sticking straight up into the air. Male tsessebe have also been observed standing in parallel ranks with their eyes closed, bobbing their heads back and forth. These habits are peculiar because scientists have yet to find a proper explanation for their purposes or functions. The periods before and after feeding are spent resting and digesting or watering during dry seasons. Tsessebe can travel up to 5 km to reach a viable water source. To avoid encounters with territorial males or females, tsessebe usually travel along territorial borders, though it leaves them open to attacks by lions and leopards. After mating, the gestation period of a tsessebe cow lasts seven months. The rut, or period when males start competing for females, starts in mid- February and stretches through March. Leks are established by the congregation of adult males in an area to which females visit only for the purpose of mating. Lekking is of particular interest, since female choice of a mate in the lek area is independent of any direct male influence. Several options are available to explain how females choose a mate, but the most interesting is in the way the males group in the middle of a lek. The grouping of males can appeal to females for several reasons. First, groups of males can provide protection from predators. Second, if males group in an area with a low food supply, it prevents competition between males and females for resources. Finally, the grouping of males provides females a wider variety of mates to choose from, as they are all located in one central area. The closer a male is to the center of the lek, the greater his mating success rate. Animal List A to Z.

The Red Duiker is smaller than the Common Duiker. Standing, it is 420mm at the shoulders. Ungulates account for the vast majority of large herbivores currently on earth. Their influence stretches across nearly every biome, and their indigenous range. This article addresses those individuals who want to known what do leopards eat. These wild cats have varied diet pattern. The smallest of the four big cats, leopards. For a male to reach the center of the lek, he must be strong enough to outcompete other males. Once a male's territory is established in the middle of the lek, it is maintained for quite a while; even if an area opens up at the center, males rarely move to fill it unless they are able to outcompete the large males already present. However, maintaining central lek territory has many physical drawbacks. For example, males are often wounded in the process of defending their territory from hyenas and other males.
