Safari at Hwange

24 January 2024: Day 6, Hwange National Park, Zimbabwe — Road Scholar Southern Africa Birding Safari. Click here to see (generally) where I am today.

Yesterday we went on a bird drive in Zambezi National Park. Today we drive to Hwange National Park, Zimbabwe for our first game drive. We’ll see many of the animals pictured above and listed below.

  • Lion
  • Elephant and zebra
  • Oryx (did not see this animal)
  • Greater kudu
  • Impala
  • Cape buffalo

During our tour the words Safari or Game Drive mean “Drive around and look for birds and animals.”

To give you an idea of what I’m experiencing I’ve included a promotional video from Road Scholar, created for one of their other African programs.

This is NOT the program that I’m attending. (The video is Program #3645, I’m on Program #21528.) However some of the locations and many of the experiences are the same.

How Are Giraffes Doing Nowadays?

17 January 2024

Giraffes are way cool. They’re the tallest mammal on earth, they hardly sleep at all (only 10-120 minutes per day), they need less water than a camel, and they have big hearts … literally. Their population is also declining. In December 2016 they were placed on IUCN’s Red List of Vulnerable species.

Have their numbers improved in the past seven years? How are giraffes doing nowadays?

Today, the Giraffe Conservation Foundation estimates the current Africa-wide giraffe population at approximately 117,000 individuals.

[Since the 1980s] this is a drop by almost 30%, a slightly less bleak picture than previously portrayed in the 2016 IUCN Red List assessment that estimated giraffe at less than 100,000 individuals. However, this updated information is based more on improved data rather than on actual increases in numbers. Unfortunately, in some areas traditionally regarded as prime giraffe habitat, numbers have dropped by 95% in the same period [since the 1980s].

Giraffe Conservation Foundation

The giraffe population assessment is complicated by their DNA which now reveals they could be split from one species (Giraffa camelopardalis) into four distinct species and seven subspecies, some of which are in good shape while others are not.

A 2007 analysis suggested six species on the map below. To get the latest four species (2021), lump [blue+green] and [pink+red]. Yellow and orange are distinct species.

The Giraffe Conservation Foundation describes the proposed four species:

  • Southern giraffe (Giraffa giraffa) includes Angolan. (Seen on our tour in southern Africa)
    • southeastern Angola, Botswana, Namibia, Zimbabwe, Mozambique and South Africa and is the animal we imagine when we see the word “giraffe.”
    • Population: 49,850
    • Needs a reassessment, might be Least Concern
  • Masai giraffe (Giraffa tippelskirchi)
    • Kenya, Tanzania and a small region of Zambia. Darker than the other species.
    • Population: 45,400
    • Endangered but improving
  • Reticulated giraffe (Giraffa reticulata)
    • Kenya and southern edge of Somalia. Its patches touch each other in a network pattern.
    • Population: 15,950
    • Endangered but improving
  • Northern giraffe (Giraffa Camelopardalis) includes Rothschild’s and Western.
    • scattered in Western, Central and East Africa
    • Population: 5,900
    • Rothschild’s subspecies (Critically Endangered)
    • Western subspecies (Vulnerable)

So how are giraffes doing nowadays? It’s complicated!

Mirror Test in the Woods

When we look in a mirror we know we’re looking at ourselves, but most animals cannot master this. In fact, baby humans don’t recognize themselves in mirrors until about age two.

@KeepingItWild set up a big mirror in the woods in Australia (i.e. “the bush”) and captured animal reactions. Interestingly many of the animals in this 8-minute video are not native to Australia. For instance: red deer, rabbits and pheasants.

According to Wikipedia, the only animals known to have passed the mirror test are great apes, a single Asiatic elephant, the Eurasian magpie, giant oceanic manta raysdolphinsorcas, and the cleaner wrasse (fish). (NEWS THIS WEEK! Apparently mice pass the test, too. See the comments!)

Sadly, in flight most birds are completely fooled. They fly into the reflection and die.

The Raccoon’s Cousin

8 January 2024

If you’ve been to the American Southwest, Central America or northern Colombia, you may have encountered a white-nosed coati (Nasua narica), the tropical daytime equivalent of the raccoon. Like his cousin he has a long striped tail, can climb trees and is not picky about what he eats.

Interestingly he loves balsa (Ochroma pyramidale) nectar and is important to the tree’s propagation. Coatis insert their long narrow snouts into the flowers, get pollen on their noses and move on to pollinate other flowers. It’s a symbiotic relationship.

Coatis are relatively rare in the American Southwest so it was cool when this one made an appearance at the Visitor Center at Coronado NPS in southeastern Arizona.

If food is plentiful near humans, coatis overcome their wariness as they have done in a big way at this park in Villahermosa, Mexico.

Inevitably the brave ones cause trouble, just like raccoons.

These animal cousins might encounter each other within the coati’s more limited range though they operate at different times — the coati during the day, the raccoon at night.

I wonder how they react when they meet each other.

“Hello there, cousin.”

Are You Saying Something?

Is this horse neighing? Is the lion roaring?

No. In both cases they have smelled something interesting, perhaps a female in heat, and are breathing through their mouths and opening their airways to take in as much scent as possible into a special olfactory organ called the vomeronasal organ.

They are making a flehmen response. On Throwback Thursday, learn more and see a video in this vintage article:

Coyote Sends Greetings

2 January 2024

Coyotes (Canis latrans) live in Pittsburgh but you might never notice because most of them keep a low profile. In Pennsylvania coyotes are hunted and trapped all year long — and they know it — so they generally avoid humans and operate at night.

Occasionally coyotes howl in Pittsburgh, usually from the woods, but I have yet to hear it. Since they’re larger than their western cousins you probably won’t see an amazing performance like this one in Tucson.

This coyote was sending greetings so important that he had to climb up high to say them.

Reindeer Cyclone

15 December 2023

Reindeer, also known as caribou (Rangifer tarandus), have been hunted by humans for thousands of years. An individual reindeer is vulnerable but the herd has a defense mechanism that protects them from humans, polar bears, grizzlies, wolves and other predators. It’s called a reindeer cyclone.

For another view, see this video excerpt from PBS Nature’s program about Vikings that shows reindeer making a cyclone to evade a hunter and it works.

Wildlife in the Borderlands

14 December 2023

Watering holes are places of abundant wildlife in Arizona’s Sonoran desert as captured on this trail cam in the borderlands. One of the night visitors is a ringtail (Bassariscus astutus), a member of the raccoon family, shown above. (There are two embedded videos below; please wait for them to refresh.)

When water crosses political boundaries animals cross, too, back and forth from Arizona to Mexico. But now the Border Wall makes most of that impossible.

This vintage article explains.

UPDATE on 15 Dec: Here’s the Border Wall.

Caught In The Act

“Hey!” says the great egret as it chases the cattle egret. “That’s my mouse!”

Cameras capture birds and animals in surprising ways. A stack of shorebirds. A bobcat on a prickly perch.

And deer running from …?

In New Jersey a buck ran through a front yard, jumped over two cars, and miscalculated the landing. Despite that he hopped out of the truck bed and ran away.

This month deer are still in the rut and still running into traffic. Caught in the act.
