AN UNINVITED GUEST

Jack’s picnic site in the heart of the Addo Elephant National Park is a good place to stop for lunch and enjoy a break from driving. Each picnic site is separated from the next by a thick hedge of Spekboom and other indigenous plants, so one does not have to wait long to get close-up views of a variety of shrub-loving birds. We were able to admire a Bar-throated Apalis – a bird heard all over the park, but which is not easily seen whilst one is driving.

It wasn’t long before a Southern Boubou made an appearance.

A pair of Cape Robin-chats came to investigate the pickings.

We are always pleased to see a Sombre Greenbul (I still think of it is a Bulbul!), which is another bird more easily heard than seen when one drives through the park.

These birds have become accustomed to the regular arrival and departure of humans, for they appeared in quick succession to comb the gravel for anything edible the previous party might have left in their wake. Within minutes of our arrival they had retreated to the dense cover of the surrounding shrubbery as we settled down to enjoy our food and conversation.

Shortly afterwards I became aware of the Cape Robin-chats calling loudly behind me – I recognised the alarm call from the many times I have heard it in our garden. One of the pair spread its tail feathers out widely, while the other ruffled its feathers as if to increase its size.

The Southern Boubou emerged from the undergrowth, making a harsh grating alarm call, while the Bar-throated Apalis danced frantically along the top of the Spekboom hedge, snapping its bill and wings – it too was clearly agitated. Something untoward was happening.

I looked up in time to see a Boomslang launching itself from the shrubbery onto the roof shading our picnic table – far too fast for me to focus my camera! We could see no sign of it on the roof, so we continued our picnic until I looked up again and saw its sinuous length squeezed into the space between the roof and the wooden slats below it.

Some of our party felt it was too close for comfort

We decided then than it was time to pack up and continue our game viewing drive.

WILL YOU WALK A LITTLE FASTER?

Seeing these two lizards scuttle up a tree trunk brought to mind the opening words of The Mock Turtle’s Song by Lewis Carroll:

“Will you walk a little faster?”

said a whiting to a snail.

“There’s a porpoise close behind us,

and he’s treading on my tail.”

BLOUKOP KOGGELMANDER

Well, that is what I grew up calling the Blue Headed Lizard or Southern Rock Agama (Agama atra). Actually, we simply called it a ‘bloukop’ whenever we saw one in the Lowveld where I grew up. As exotic as they look, they were simply part of our environment as far as we were concerned: nothing out of the ordinary. I feel very different about them since moving away from that part of the country, for I have not seen any in the Eastern Cape.

Only the males sport a bright blue head; the head of the female is smaller and paler in colour. This photograph was taken at Satara Camp in the Kruger National Park some time ago.

DRAMA IN A PUDDLE

There was a puddle in the road. Something caught my eye as we passed it: just a glimpse of something unusual. “Stop!” I called out. “Reverse please, but not in the puddle!” This is what we saw:

Time marched on, so we did not witness the final demise of the lizard – or did it get away? It was definitely not going down without resistance!

UPDATE: Thank you to Chad Keates (see comment below) for identifying this as a Cross-marked Whip Snake (Psammophis crucifer) eating a Cape Skink (Trachylepis capensis).

 

MONITOR LIZARDS

There is a game for four players printed on the reverse of the map of the Mountain Zebra National Park. Photographs of the animals, a few prominent birds, and a Rock Monitor Lizard have been allocated various points – adding to the fun of totalling one’s views at the end of the game drive to see who spotted the most animals first along the way. It is a great way of keeping younger members of the family interested for longer than they might else be.

Looks can be deceiving, especially when something is seen in haste and the ‘proof’ is a small photograph worth eight points! Thus, while we were parked next to Doornhoek Dam watching the antics of various water birds, the youngest member of our party looked down and called out triumphantly “I am watching a Rock Monitor Lizard!”

She must have had a good view of it from her window; I had to twist around and then try to focus with my telephoto lens in a hurry – not very successful with the grass in the way! In two ticks it had slipped into the water from where it kept a beady eye on a pair of Red-knobbed Coots swimming nearby. They must have been aware of its presence too as they immediately swam out a little further from the grassy bank.

‘It’: upon reflection, this was not a Rock Monitor Lizard, but a Nile Monitor Lizard (Varanus niloticus), also known as a leguaan or waterlikkewaan in South Africa. I am grateful for the beautifully clear photographs that Chad Keates has published of the two types of monitor lizards in his blog https://nextgenherpetologist.co.za/2016/12/23/the-monitor-lizards-of-southern-africa/ which easily clarified the identification as my own photograph is ‘waterlogged’ as you can see:

This one, photographed at Transport Dam in the Kruger National Park was more co-operative:

A Rock Monitor Lizard (Varanus albigularis) kept us entertained one late afternoon in the Satara Camp of the Kruger National Park, sending doves and glossy starlings flying as it made its way across the ground:

Then climbed a tree!
