Geoffrey Kay, birding optometrist, put together a trip to Namibia in 1986.
We landed in Windhoek, picked up a VW kombi and rigged it up with a nice big hebcooler in the back. Ice, beer, gin & tonic. Now we were ready for any emergency.
West to Daan Viljoen game park where a lion’s roar welcomed us that first night. On through the Khomas Hochland into the Namib Desert. Then on to the Atlantic Ocean at Swakopmund. On to Spitzkoppen; Usakos; Erongo Mountains; Karabib; Omaruru; Otjiwarongo; and Outjo;
Then up to Etosha: Okakuejo, Halali and Namutoni camps. In Etosha we saw a very rare night ‘bird‘; Seldon seen .
Then on to Tsumeb; the Waterberg; Okahandja; And back down to Windhoek.

We spotted 200 bird species that week! Also a new mammal for me: The Damara DikDik.
Jurgen Tolksdorf newbie birder spotted many birds for us with his keen eye. “What’s that?” he’d say. In Etosha one night we woke up to the b-b-b-b-bhooo of a white-faced owl near our tents. We shook everyone awake and grabbed our torches and binocs and went to look for it. Except Jurgen. He said “A WHAT?” and rolled over and went back to sleep. We searched in vain and got back to bed very late, disappointed.
Next morning after a short night’s sleep, on our way back from breakfast we met Jurgen who had risen late after a long night’s sleep and was now on his way to eat. While we chatted he looked up in the tree above our heads and said “What’s that?”.
While we were birding in Namibia in 1986, a comet buzzed past us.
Englishman Edmond Halley, in his 1705 Synopsis of the Astronomy of Comets, used Newton’s new laws to calculate the gravitational effects of Jupiter and Saturn on cometary orbits. He realised that a comet that had appeared in 1682 was probably the same one that had appeared in 1531 (observed by Petrus Apianis), and 1607 (observed by Johannes Kepler). Halley concluded they were the same object returning every 76 years and predicted its return for 1758. He died in 1742 before he could observe this himself, but his prediction of the comet’s return proved to be correct! It was seen on 25 December 1758.
And then – significantly – again by us in Namibia in 1986, thus conclusively proving Halley was no poephol even if he was an Engelsman.

Johannes Kepler in 1607
Edmond Halley in 1758 if he hadn’t died away – and . .

We lay on our backs in Etosha on a beautifully clear night with our birding binocs and telescopes and had a good look at a tiny little fuzzball* far away while a white-faced owl went b-b-b-b-bhooo in the near distance. If the truth be told, our view of Halley’s looked more like one of the tiny dots in the right of this picture rather than the swashbuckling zooming thing on the left. But it did have a tail, so we convinced ourselves we HAD seen it. Halley’s Comet!!
*Even the keenest astronomers said the view of Halley in 1986 ended up being underwhelming in observations from Earth. When the comet made its closest approach it was still a faint and distant object, some 62 million km away. However, we humans did send a few spacecraft up which successfully made the journey to the comet. This fleet of spaceships is sometimes dubbed the ‘Halley Armada.’ Seven probes were up there looking, with the European Giotto craft getting closest – to within 596km. The Challenger space shuttle would have been the eighth but it blew up two minutes after it launched.
The Giotto got this pic of the 15km X 8km X 8km rock:
Halley’s is due again on 28 July 2061. I’ll be keeping a 106yr-old eye out.
