Okay, Rooies, put your left foot in, put your right foot in, spin it around, and shake it all about. Now you're doing the hokey-pokey; great movement there. :twisted:

Answer 2: It is to accommodate the shape of the embryo.
Answer 3 The oval structure is stronger.

(I hope one is correct :doh:)


Actually two are correct, Rooies - 1) and 3). In certain species, especially those that nest on shallow ground or cliff faces, the oval shape indeed prevents eggs rolling away. And the oval structure can be stronger in certain situations. Which deserves two claps ... :clap: :clap:

:clap: Indeed, Huntsman (and Rosemary), the oval shape to the eggs eases efficiency of birthing the eggs down the canal. Round eggs would be far more painful and may even get stuck.

The Forktailed Drongo sometimes manages to steal food from the Meerkats in KTP. What clever scheme has he got?

Hi there. The Forktailed-Drongo mimics the alarm call of the meerkats which make them run for their burrows. Leaving the bird to eat the snacks they left behind.

Where is Rooies ?
KNP is sacred. I am opposed to the modernisation of Kruger and from the depths of my soul long for the Kruger of yesteryear! 1000+km on foot in KNP incl 56 wild trails.200+ nights in the wildernessndloti-indigenous name for serval.

Rooies is alive and well. So, what is going on lately? I changed firms and are now with a Kruger fanatic. He is not a forum member but regularly posts photos in the Gallery. My new colleague is going on a three week trip to Kruger at the end of July. I will try and convince him to join and bring us a travel report.

Sorry for keeping everyone waiting. I was not aware I have to provide the next question when I answer correctly :roll: . Still need to figure out how some if these topics work, sorry.

Here goes: Which birds swallow their own feathers in order to protect their throats from damage when regurgitating small bone fragments of prey items?

Agree with MarkusF: "It is a bird which lives in water and is called the Great Crested Grebe. It eats its own feathers and feeds them to her young ones too.The Grebe has a unique excretory system. It throws out one or two balls of excreta through its mouth on every alternate day. The staple diet of Grebes is fish. So, the ball of waste has indigestible fish bones and scales apart from gastric parasites".
