ANTELOPE

          Africa has a surprising diversity of antelope species, of which we saw quite a few.  This page devotes a paragraph to each species, focusing on their ecological niche and interesting behaviors, arranged by size.  A thumbnail image with that paragraph links directly to the slide sequence on that species, without going through the index page of thumbnails, if we have more than one image. ( If we have only one image, a click on the thumbnail will display an enlarged image; get back here with the "back" icon near the top left of your browser menus.)


DIKDIK (KIRK'S): We saw Dikdik at Sinya, on the way from the Ngorongoro Crater to the Serengeti and on the Serengeti.  They pair for life and mark and defend a territory of an acre or so.  Interestingly, the male defends the pair's territory against males, while the female defends it against females.  Their territory usually includes some dense brush, as this is their cover to protect themselves from various predators.  We got glimpses of quite a number of pairs, but they usually dashed away before cameras could be aimed.  The pair we saw beside the road from Ngorongoro Crater to the Serengeti main gate didn't take flight - thus the fairly good image of them.  Male has small, straight horns, females have none.  This pair may be mother and offspring, rather than a breeding pair.  Shoulder height  = 36 - 41 cm
DIKDIK
THOMPSON'S GAZELLE: We saw Thompson's Gazelle at Sinya, in the Ngorongoro Crater and on the Serengeti.  There are about 225,000 of these small antelope on the Serengeti.  They have a distinctive black stripe which divides their tan upper body from their cream-colored lower body.  Both males and females have horns, but the males' are much larger.  Most of them make the annual migration around the Serengeti with the wildebeest and zebras, but a few stay year around where we were.  We saw a hyena run down and kill a young Thompson's Gazelle, probably only a few days old, which had been born out of season, the reason for its vulnerability.  They move about in herds of a hundred or so.  They weigh up to 40kg (100#).  Shoulder height  = 64 - 69 cm THOMPSON'S GAZELLE
SPRINGBOK: Springbok are a small antelope of the arid plains of the same general size as Grant's Gazelle.  We saw them only once, shortly after we left Sinya Camp.  (This may not be springbok, as our guide book says these live only farther south.)  Shoulder height  = ? between Thompson's and Grant's Springbok
GRANT'S GAZELLE We saw Grant's Gazelle in the Ngorongoro Crater and on the Serengeti.  The Grant's Gazelle intermingle with the Thompson's.  They are about half again taller, and twice as heavy, and lack the black stripe along their sides.  Other than size they behave very similar to the Thompson's.  There are about half as many Grant's on the Serengeti as Thompson's.  Weight up to 80kg.  Shoulder height  = 81 - 99 cm Grant's Gazelle
IMPALA: Impala are slightly taller than the Grant's, but weigh less.  They eat a vide variety of plants; their diet is so varied they sometimes are referred to as "the goat of the plains."  The males' horns sweep back then up in a wavy form.  We saw a few lone males and two large herds of females , one during the one rain we experienced.  Something like 70,000 live on the Serengeti.  Weigh up to 50kg.  Shoulder height  = 92 - 107 cm IMPALA
WATERBUCK: Waterbuck live in open woodlands and savannah, but usually near water.  We saw them near a perennial stream from the balloon ride.  They are rare relative to the other antelope, numbering something like 1,500 on the Serengeti  Males weigh up to 270 kg.  Shoulder height  = 122 - 137 cm  Reedbuck
TOPI: We saw Topi only on the Serengeti, where they number 40,000+.  Widely distributed; fast runners.  Number about 40,000 on the Serengeti.  Males often stand on sentry on abandoned termite hills.  The ones we saw were on the dark side of the color variation.  Lighter colored ones have much more visible purple blotches.   Weigh up to 250kg.  Shoulder height  = 122 - 127 cm TOPI
WILDEBEEST: We saw Wildebeest in the Ngorongoro Crater and on the Serengeti.  Wildebeest are the major migratory antelope on the Serengeti, numbering from 750,000 to 1,000,000, depending on the date relative to the various stages of the migration and reproduction.  Calving occurs mainly in the far southeast of the Serengeti in January.  Calves must be able to run within minutes of birth.  Those in the Ngorongoro Crater seem to be much more sedentary and well-fed than those on the Serengeti.  Although most migrate, some stay in the central Serengeti year round.  We saw moderate numbers there, although we have no images of them.  Weight around 250kg.  Shoulder height  = 132 cm WILDEBEEST
ELAND: We saw Eland only on the Serengeti.  Eland are common but shy with an estimated population size of about 12,000 on the Serengeti.  Eland live in shrub and grassland, browsing mainly at night when vegetation has more moisture.  They are not territorial, and are not especially migratory.  They display substantial color variation, from rather gray for mature males to a fawn color similar to Thompson's Gazelle to almost a red, depending on sex and age.  Horns are straight with a spiral ridge.  Weight up to 900kg.  Shoulder height  = 175 - 183 cm ELAND
