Many still considered him a youngster. Only 6-7 feet long he was little compared to the monsters of Lake Turkana, many photographed at over 25 feet. But he didn’t feel young, anymore.

Born on a buried sand nest on the edge of the great Mara River, he ate voraciously his first several years, swimming madly away from the large bull frogs the size of soccer balls that gobbled up little crocs by the dozens.

A few years later when he reached a couple feet long he had to eat only a few days each week. He lie motionless just under the water at the shoreline, jumping up twice his length to snatch a bird trying to flee. Soon, irony of ironies, he was hunting the frogs.

When he reached his early teens he was too big to hide any longer among the water lilies in the crags of the great Mara. He began to crawl out onto the rocks to get warmed by the sun like the big guys.

It wasn’t long ago that he started to sleep more and more. When he woke hungry he waited for a small impala coming to drink and that was only a few times every couple months. But back then he ate his hunger rather than the impala if there were any big guys around. He’d seen some buddies persist only to lose the prey to one of the Mara monsters, and sometimes even parts of their snout.

Now at a robust 7-8 feet he found himself with no appetite except twice a year. He slept the rest of the time behind a secluded and log hidden under a big leafed tamarila bush that hung over the river.

His hunger woke him the day we saw him. Perhaps, too, he felt the ripples of the big guys slipping into the river. Whatever it was he was famished.

So no longer junior he couldn’t hang back an instant longer, because the moment he started to swim again after his several month sleep his appetite grew extreme. He hurried out no longer deterred by the current, his sleek powerful body cutting through the turbulent Mara waters as if it were a still lake in the mountains.

Suddenly he was with others his size swimming but without any real direction, nothing to hunt in the deep middle of the river. Then all of a sudden he saw one of his buddies snapping at a head with horns that bobbed among three or four of his peers. The horns weren’t sharp at the end or shiny in the sun. They looked puffy and grey.

The four 7-foot crocs gnawed and slapped their jaws all over the thing but it didn’t soothe their appetites. Soon they backed off and encircled it like the spokes in a wheel.

Finally the 6-month old skeleton sunk back into the water. His appetite soared. He wriggled, challenging his peers, but they quickly swam away. He stayed right there in the middle of the river. He knew something was on the way.

By the end of our 8th day in the Serengeti, our 18th on the overall safari including Kenya we’d seen virtually everything but a rhino. Most travelers lack the inclination for spending so much time and money on an East African Safari today but it reminded me that in the old days I rarely guided a trip that was less than 23-25 days. Marlin Perkins’ first safari with supporters of the Lincoln Park Zoo in 1957 lasted two months and six days!

We intersected the migration big time two days ago in the western corridor. We spent a night at a beautiful camp on a hillside overlooking Seronera and the next morning watched a 5-mile long file of wildebeest race across the valley below. The migration has yet to reach further north, but our schedule had us the last two days in Tanzania’s far north just in case the migration had been early.

On our way up we saw our last group of lions, bringing our total to 46. The family of 13 was draped onto a very small kopjes in the middle of a vast flat prairie like bits of discarded bread dough thrown over a broken spatula. We left the rock of lions just a tad bit south of Lobo and continued moving north. Game became very scarce. The grass grew five feet high.

Our last game drive scoured the veld up to the Mara River and the Kenyan border. This is Tanzania’s Mara District, and the terrain looks almost exactly like Kenya’s Mara: gently rolling hills, verdant and bushy.

But here in Tanzania south of the great Mara it’s higher and drier than just north over the great Mara River in Kenya. There in Kenya the valley is much better watered, less rocky and has better grass.

So our last game drive was pretty scant. The drive was interrupted with a bit of excitement as we tried and failed to pull another tourist rover out of the black cotton soil in which it was stuck. (Not really a good idea to travel in these parts during the rainy season with only one vehicle. Moreover this one had a broken 4×4 system, so it was doubly doomed and got what it deserved.)

We offered the lovely couple from Barcelona a lift back to their camp but they opted to remain with their driver until another vehicle was sent from their camp. We confirmed this happened by radio before we returned to our camp later that day.

The other notable event was sighting about a dozen giant crocs in the Mara River. Generally these 12-18 foot beasts hide themselves for most of the year in a dormant state. But they know the wilde are coming. This is one of the two times in the year they eat: when the wilde come, and when the wilde go back.

So they were out on the sand banks waiting in the sun or slithering anxiously through the river, positioning themselves for the hundreds of thousands of beefsteaks that will arrive probably in the next 2-3 weeks.

We even saw four trying to devour the head of a wildebeest. We didn’t see the kill and it was possibly the skeleton of last year’s migration, pulled from its crag under water.

So it was a very soft ending to a great safari.

As Steve said to me at our last dinner in camp, it’s a bittersweet time. Everyone looks forward to going home, but no one wants to leave.
