Herald Snake Hunt

I never leave home without a macro lens. There always seems something to photograph, even when back at camp after game drives or during rainy weather when most photographers pack away their gear. One’s back garden always seems to provide some incredible sightings and in fact some of my favourite images have been taken right in my back yard.



I recently stumbled upon this fantastic scene at home. A fairly large Herald snake had gotten hold of a large Red Toad, probably hunting it from within the hollow log pictures above. Once immobilized the snake could not get the toad back into the tree hole and was left to consume it from a somewhat precarious (to say the least!) position.
 
Painstakingly slow the snake managed to consume the prey until the very last bit.

 Whether the snake would eventually make a meal of its quarry was anyone's guess which meant that I had to stay with the snake quite a while to determine and photograph the unfolding events. These things take a while though and I was very fortunate that I had time on my hands that day. Scenes like this certainly do not come around too often and it was indeed a pleasure to witness such drama unfold almost from start to end.

Nesting Chameleon


Sometimes the most remarkable sightings happen in the least expected places. The garden for instance. Now I must add that I do not live out in the absolute wilds anymore but I have the likes of Egyptian cobra, Narina Trogon and a wide variety of other creatures in my garden and in the hills at the back, even Leopard.

A few days ago I stumbled onto this scene. A Flap Necked Chameleon in the process of laying its eggs. To say that this animal was inching forward as it dug its nest would be optimistic; they’re not exactly known for their speed, are they? From the time I observed it the first time it took about 24 hours to finish the job of digging its hole in rain soaked soil to laying the eggs and covering up the hole again and departing, never to see its own young again. Now in about 220 odd days they eggs would hatch and the youngsters will emerge. Its marked on my calendar so watch this space.

Where all the action took place. Slap bang in my garden.

Private Lives of Pygmy Falcons


A sight as distinct to the Kalahari as the enormous Sociable Weaver nests they commandeer as nesting sites is the diminutive Pygmy Falcon. The tender colloquial name of Sneeuvalkie (Snow Falcon) given by the locals to this, the smallest African Falcon is harshly juxtaposed against the realities of the thirst-land wilderness it calls home.

Whilst leading a photographic safari for C4 images and Safaris we were very fortunate to observe a pair of Pygmy Falcons in the vicinity of a large Sociable Weaver nest in the Rooiputs campsite on the Botswana side of the park.

As it was approaching the breeding season these birds were very active around the Sociable Weaver colony in anticipation of spring. Both birds would arrive at the weaver colony and sit in close proximity to the nest chamber. The female, easily distinguished by her chestnut back would then enter one of the chambers from where she would give regular, albeit feint calls. A few minutes later she would exit the chamber and return to the awaiting male perched outside. At this stage he would mount her and proceed to mate with her, a sequence of events that they repeated regularly throughout the day. During one of their escapades a second male suddenly arrived on the scene. The attending male immediately acted aggressively towards him and at one stage they nearly tumbled to the ground, all of which was in line with my existing knowledge of an intruding male.


"A" male presented the female with an agameaas a nuptual gift...


At a later stage one of the males presented an agama to the female, a nuptial gift she happily accepted. After feeding on the reptile for quite some time with the male close at hand the second male arrived on the scene. The female immediately took off with the two males in hot pursuit. All of this still behaviour that can be expected in a situation where an immigrant male is trying to usurp breeding rights but not tolerated by the resident birds.


...which she readily accepted.

During one of the mating rendezvous described above the second male arrived on the scene and perched very close to the mating pair. Much to my surprise the impostor was tolerated by the resident male, even as the resident proceeded to mount the female. Imagine my surprise when shortly after the male dismounted, the “impostor” casually mounted the female and proceeded to copulate with her as well!

The female Falcon allowed both males to mount her.
The reversed sexual dimorphism, the fact that the female is more brightly coloured than the male is in line with Polyandrous birds such Painted snipes and my guess would be that this is in fact what is happening with Pygmy Falcons. However only detailed studies and genetic analysis would reveal any shared paternity.
