Comparative Canid Behavior

Monday, August 31st, 2009

This summary doesn’t begin to address the subject in depth, to do so would require a book, but I hope you’ll find what I’ve written interesting nonetheless. My biggest problem with this was not spending all week on it… the topic is so interesting, and almost every fact led to a question. (Territorial? Well, that’s a highly variable concept. How does it differ between species, say dogs and wolves for example.) You can see the problem here, but one of the great things about science is that it every answer generates new questions. That’s heaven for discovery junkies like me.

AFRICAN WILD DOGS  Lycaon pictus:

Also known as Cape Hunting Dogs or Painted Dogs, these canids are not “dogs” at all (note they are in a different genus than wolves and dogs). Called the wolves of Africa, they are highly social, territorial carnivores who are more dependent on group hunting than any other canid. They specialize in medium sized prey (Impala are their preferred prey) and like Hyenas, tend to rely on running their prey to exhaustion rather than the classic stalk and pounce of some canids and most big cats. (They also, like Hyenas, hunt mostly at night, thus stalking is of less importance under the cover of darkness.) They do NOT run in “relays” as often described, but tend to run in loose groups, well spread out, so that a zig-zagging quarry has a higher chance of running into another pack member when they change direction. AWDs have incredible stamina: they can run 5 km at 30 mph.

I’m not sorry I missed seeing a kill. AWDs have an incredibly high success rate as hunters (about 85%) and usually disembowl and begin consuming their prey before the animal is dead. Granted, it is probably in shock, and well might not be feeling anything at all, but I’ve seen a crocodile consume a Gazelle, and 3 African Bullalo kill another full grown buffalo, and a lion with a freshly killed zebra foal–and that’s enough for me.

Their social system is similar in many ways to that of wolves. There is usually only one breeding pair (but note there are exceptions in wolves, not sure if true in AWDs), along with non-breeding adults who also care for the young and provision the mother and pups. Unlike most social mammals in which the males leave the group and the females stay, related males stay in the pack in this species and older females emigrate if the pack becomes too large. They are completely reliant on being in a group. One study I read said that less than a group of less than 6 or 8 AWDs were incapable of successful reproduction (due no doubt to less predatory success). Their packs can become quite large, sometimes as many as 20 to 40 dogs will live in one pack.

What’s different about AWDs and Wolves is how the breeding pair maintain their rank. Apparently there are very few overt displays of aggression; you see almost none of the facial displays, growls or dominance  related actions that are commonly seen in wolves. AWDs were believed at one point not to have a social hierarchy, but careful study found that wild dogs assert their social status by assuming the same stalking posture that they use when hunting or by simply supplanting (taking the space of) another. You DO see a lot of submissive behavior, from ears-back, toothy-grinned submission displays, food begging & whining. Adults will often regurgitate food to adult pack members who missed out on a kill (which happens often, since the hunting pack is so dispersed and the food is usually consumed within just a few minutes.)

The Illustrated African Wild Dog Story

Friday, August 21st, 2009

As you know if you’ve been following the blog, 1/2 the folks who went to Kenya continued on to Botswana. We all knew that seeing Wild Dogs wasn’t a guarantee, but we had high hopes because we were going where and when our chances were highest. (And no, in response to one comment, there are no [African] Wild Dogs in the states, we’re talking another species here, see photos below.) We stayed at Chitabe Camp in the Okavango Delta, owned and run by Helene Heldring and David Hamman, and very close to the research station of Tico McNutt, who has been studied AWDs for over twenty years. We knew that he had radio collars on most of the packs in the area, and we knew that it was still denning season, meaning that the adults tended to stay put more than usual. Still, as an experienced naturalist told us “Seeing AWDs is a gift you can never count on.”

Finding the dogs turned out to be the adventure of a life time. First off, 7 of us got split off from the rest, missed our plane and arrived 1 and a half days late. (Actually barely made it, bush plane couldn’t land in the dark and we and our luggage were literally thrown from one plane to the next in Maun with only minutes to spare.) The six of the group that made it on time (Barbara, Barb, Lisa, Jane, Debbie & Pam) spent 4 hours the first afternoon and 14 hours (really) the next day looking for the dogs. One of the pack was radio-collared, but you have to be within 2 km to get a signal, and the dogs had moved from their usual area because of floods earlier in the year. They finally found them late in the afternoon of the 2nd day, about two hours drive from our tent camp.

Re-united, we all (with a few exhausted exceptions) took off at 6:30 the next morning, driving back to the area where the dogs had been seen.  First we drove about an hour and half on what we would call a track and Botswanans call a road. A plane had been circling overhead looking as well, and the pilot found the dogs and radio’ed in coordinates. After approaching the area, we left the sandy rutted track and began driving ‘off road,’ which included driving not through a woods of Mopane trees, but over them. Imagine driving toward a 12 foot tall tree, with 3 or 4 three inch wide trunks, and simply driving into it and over it. Absurdly, the trees pop back up like cartoon figures, and the damage to the area is minimal. Still, the camp and researchers only go off road when they are doing research and have no choice.

Here’s Tico holding up the antenna, looking for a signal from the collared dog:

After about 45 minutes, Tico said “There!” And there they were. First we saw an adult, and then immediately came upon this scene:

The photo is a bit fuzzy,  my apologies.  The light was a bit low, but mostly I was shaking with excitement. The 12-14 pups (we were never totally sure) were seeing a vehicle for the 2nd time only in their life, and they immediately took off after this photo was taken. Unfortunately, the pups had just developed to the point in which they no longer dashed down into the den when they were frightened. That meant that instead of staying still, the pups ran off and the adults had no choice but to run after them. We followed slowly through (and over) the thick, brushy woods, stopping often to avoid scaring the pups, Tico always holding up the antenna to keep our electronic connection with them.

Lucky for us and for Tico, who wanted to radio collar another member of the pack, the pack stopped after about 30-45 minutes, and we were able to stop close by and watch them while Tico prepared to place a radio collar on another individual. (He always tries to keep 2 members of the pack collared, since mortality is high and losing a radio collared pack member means losing the pack.)

We all sat breathless as Tico prepared the tranquilizer and dart gun, and groaned as a group when his first shot was lifted by a puff of wind and landed in the sand. He prepared another, seconds counting down, and this time the dart bounced off the hip of the female he was targeting. More groans all around. However, it might have been a blessing, because he had wanted to collar “Jones,” the breeding male and had decided against him because he didn’t look settled enough to get close to. (I think that was the most fun I had on the entire trip… realizing that I too had concluded that Jones wouldn’t stay still if we drove close: even though he was lying down, he had never turned his head toward us, although we were only 30 feet away. I loved being able to transfer reading a domestic dog to reading an African Wild Dog!)

After the second darting attempt, Jones looked more settled, so we slowly approached him (in our vehicle), Tico raised the dart gun one more time, we again held our breaths and this time the dart flew straight and true, into Jones’ thigh muscle (only safe target). Jones lept up, ran 10 feet away, and then circled around for a few minutes, lying down conveniently in the shade. Tico and driver BeBe then took measurements and collared Jones, and eventually we all were allowed to come down and see Jones close up, pet his stiff fur and look at his two horrendously infected teeth. Ouch.

Here’s Erin getting a once in a lifetime encounter with one of the world’s most endangered species:

And here’s Tico giving Jones the andidote, after about 40 minutes of data collection and collaring:

We stayed with Jones until he was well up and recovering. I asked Tico if there were ever challenges to a dog’s social status if it returned to the pack a bit woozy, but he said he’d never seen a sign of it. He had worried about that very thing his first year of research, and actually removed the dog from the pack for a day to avoid a power shift. Eventually he found that to be unnecessary, and has not seen any problems in all the subsequent years he’s collared dogs.

This post is getting a bit, uh, lengthy, so I’ll postpone talking about comparative AWD/Wolf/Coyote/Dog behavior til later (if you’re interested… or is this getting boring?  let me know, truly!).

Last comments: Someone with the improbable name of Tico McNutt (I mean, really!) can be one of the most inspiring, dedicated, knowledgeable and kind people imaginable. He has three graduate students working with him now, and has spent over twenty years working with the highly endangered wild dogs. I don’t doubt that he is one of the reasons that dogs are holding their own in Botswana now. And Chitabe Camp is without question one of the most amazing places on earth. The tents are gorgeous inside (complete with blow ups of David’s astounding photographs over your comfy bed), baboons play on the roofs of the tents outside, the entire place is brilliantly run and profoundly eco-sensitive. I said this was my last trip to Africa, and it probably is, but if anything pulled me back it would be the AWD research and Chitabe Camp.

Here’s one more photo of the dogs (sorry, I just can’t resist):

Why Grandma, what big ears you have!

Meanwhile, back at the farm: No photos yet, but it is green and lush and cool and I feel like I’ve fallen into an emerald. Lassie and Willie and Sushi are wonderful, two of my ewes are struggling with a still unknown disease, the lambs are thriving and the grass is bountiful. Oh my it is good to be home!

Gnus from Africa (sorry)

Monday, August 17th, 2009

THIS WAS WRITTEN on August 11th, but not posted til now. So don’t get confused, it’s out of order!

In transition, 10 minute to write. in nairobi between tent camp on edge of maasai mara in masai village and flights either to home or to So Africa for those of us going on to Botswana.  Trip amazing, too much to process while it is happening. Picture:

The ultimate ‘hard eye’ from a lioness 10 ft from YOU while she walks by your van with her cubs.

A leopard getting beat out over a kill by a lion.

Streams of wildebeest drawing lines across the vast and open mara, always led by zebra.

Elegant and yet adorably cute Thompson’s gazelles switching their tails in time to the bumps in the road.

More dust in your hair than you can ever imagine getting out.

Talking to young maasai warriors about their belief that cows = money, and wondering how long they can continue gathering cattle now that they tend to stay in one place.

Making life long friendships with driver guides Joe and John and Hamm, and especially Tony, our own African Angel.

Hearing that Lassie looks all over the house several times a day.. for me? and trying not to turn into a puddle.

gotta go, car leaves for airport in 20 min. next adventure, here we come….

(and everyone is well.. a few tough days for some of us, me included, but everyone doing great, though all ready for a long bath and long sleep!)

African Wild Dogs YES!

Monday, August 17th, 2009

Back in the Jo’berg airport again, but this time after having spent two days in the Okavango Delta at Chitabe Tent Camp. 1/2 of us arrived 1 1/2 days late, having barely made it when our last flight was delayed and the sun’s descent meant we might not be able to take the small plane to the isolated camp: couldn’t land after dark. But we squeaked in, blank eyed and exhausted and then spent two days in heaven.  We not only saw AWD’s, we were able to be with Tico when he radio collared “Jones,” the dominant breeding male of a pack about two 1/2 hours away from the camp.

The group that arrived on time spent 5 hours one afternoon/evening and 14 hours with  Tico and his radio transmitter trying to find the pack, which they found late the afternoon the rest of us arrived. We left early the next morning, in hopes the pack hadn’t moved, and after driving not through a woods but over it (to be explained when I return) we found one adult, and then bang, right straight in front of us: 12 or 14 pups, just out of the den. The adults are habituated to people, but the pups were just out of the den in that they were no longer running back to it, so they took off and the adults followed. We carefully followed them for about 45 minutes, radio antenna held on high, and they finally settled down, pups and adults both.

It was a wonderful experience for people who want to see what field work is really like: Tico’s first 2 darts missed, we were almost out of time (he had a plane to catch later that day) but the 3rd time was a charm, and Jones got the dart full in the thigh muscle (only possible target), and went down close by in 10 minutes.
We all got to watch Tico take all his data, put the radio collar on Jones, and then we all got to get out and touch Jones, look into  his mouth (poor guy, two horribly infected teeth), pet his stiff, hard fur. It was miraculous. Most people never ever get to see dogs, even after spending hours, days, weeks, looking, and we spent most of the  morning with them. Amazing.  Photos to follow.

Three more planes to home (have taken 2 already). Others waiting for a terminal to check in, so will go now. All on trip are fine, full of stories of wonder and adventure. Some good, some not so good, but all experiences to cherish the rest of our lives.

I’m coming Lassie….. soon.

Botswana 7: Forgotten, but Not Gone

Friday, August 14th, 2009

Well, here we are, 7 of us anyway (Matt, Kelly, Meg, Beckett, Erin, Jim and me for any relatives trying to get news), in the Jo’berg airport, over a day past when we were due to arrive in Botswana. Due to a series of unfortunate events, we were stranded and alone in the Nairobi airport 2 nights ago. Caught in a legendary traffic snarl in Nairobi, we spent 2 and 1/4 hrs either motionless in traffic or driving hell bent for leather, going THE WRONG WAY on the other side of the highway. Nairobi Airways denied us boarding anyway, even though we there almost an hour before take off and their rules said we’d be okay.  Three hrs and $1,000 later, we booked for the next morning, but bad news…. next plane from Jo,berg to Maun delayed, but will get there tonight, ….we think.

Most importantly, this is the most wonderful group of people imaginable. Smart, flexible, supportive, funny funny funny funny.  To them all, to Kelly and Matt (who own this laptop) and Meg and Beckett and JIm and Erin: REMEMBER THE BISCUITS

Lions chase off vultures

Friday, August 7th, 2009

Watched adult female and two subadult cubs (3-4 yrs? still some spots on legs) chase vultures off a recent zebra kill. Elephants coming in out of the hills to feed in the amboseli swamps, we’ll see more of them later today. Am meeting with camp naturalist to learn more… saw an animal that looked exactly like an African Wild Cat…. which is pretty much exactly like a tabby house cat.  How tell difference? At night the zebra and antelope come right up to the veranda. Have to watch out for vervets, who try to steal the sugar off your table and dash in your room. Yesterday we caught one on our luggage, just starting to unzip it. And yes, we’ve seen lots and lots of robin egg blue testicles (on the vervets, honest.  they even have a penile display that zoologists patriotically call the “Red White and Blue display.” Gotta love it.)

Running out of computer time, don’t know if will have access again in Kenya. This lodge is the biggest we’ll stay out, otherwise we are in small, tent camps. The facilities are lovely, even can get a massage (!) but there are a lot of people and we’ve been spoiled by our first isolated tent camp in the Tsavo. Will be similar tho in the Masai Mara, staying in a small, isolated tent camp.

Love to everyone, with a heart ful of gratitude to be able to experience such an amazing place, and to be so blessed with so much. Wish I could send photos, but am taking bunches and will post when return.

Pride of 9 Lions!

Thursday, August 6th, 2009

Here we are in Amboseli. 9 pm, long day, ending with dinner watching gazelles, zebra and wildebeest walking past the dining room. went on game drive in evening, found pride of 9 lions:2 black maned males, 2 cubs and 5 females. some of us saw them very closely, my van not right next to the van, but still amazing. cubs playing on top of mom, males looking bored and regal. all getting ready for nightly hunt.

Is just as wonderful as you would hope. People so kind, country astounding–vast and huge and full of contrasts. Dry sand dirt and electric red robes of  Maasai. Is sadness too–terrible drought causing suffering to people and animals alike. Maize crop has failed for people. Grass gone for grazers, so hippos and zebra suffering terribly. Browsers like giraffe and Kudu antelop doing much better. Birds everywhere, so beautiful you can’t believe they are real. Lisa, one of group, got a photo of a Lilac Breasted Roller (check it out) that will knock your socks off.  It’s hard to believe some of the birds are real, they look like Dr. Seuss or Disney animals.

Too much to describe in my 15 min of internet time, but have seen hyena, black backed and golden jackals, absurd and amazing numbers of elephants (including babies, “tembo toto” in Kiswahili. (Baby giraffe are Twigga Toto. How cute is that?

We are reveling in wildlife, country and people. Went to a Maasai school today that we had arranged before hand. Chlldren sang for us, so sweet our hearts could barely stay in our bodies. We taught them how to play Hokey Pokey dance (Barbara’s idea.. such a stroke of brilliance). The kids loved it, but not as much as we, all holding hands in a big circle, laughing together.

Group that came is delightful, couldn’t be better. Each van, of 4-6 people is developing it’s own personality, including the Impala Harem. I’ll let them explain… if they dare.

Tomorrow it’s a 6:30 game drive (best to see cats) for some, visit to a Maasai village for others. Then back for breakfast, and a game drive or nature walk.

Gotta go do some laundry. So much dust in my hair and clothes I could sell bags of sand for highway departments…

More soon, if can…
