T / F

a. Certain birds, such as snipes, are able to bend certain sections along the length of their bills independently of the rest of the bill. This enables them to transport food up their bill without having to open the whole bill.

b. A worker bee progresses from one task to the next within the hive, in a fixed system of age dependent specialisation.

c. The Eland is predominantly a grazer.

1. True

The bill of a snipe, for example, can be opened near the tip. This occurs through a rotation of the quadrate whereby it moves the jugal bar forward. The basal two-thirds of the bill is rigid, hence the mandible is bent further.

2. True

The basis for the division of labor within the hive is the age of the worker. The worker begins its life taking care of the storage cells of the hive, then moves on to brood care and food storage, and ends its life as a forager. The adaptive significance of this labor schedule is that it extends the life of the worker by establishing a system whereby the young worker bees spend the majority of their lives inside the hive where they live in the protected environments of their colony. Once they become foragers, they are susceptible to predation, bad weather, and wing burnout.

The primary cause of death for a worker bee is burnout. That is, their wing muscles only have a certain amount of flight, generally 800 kilometers, and when this point has been reached they are incapable of fulfilling their role and taking care of themselves.

3.False

Although the eland is often considered a plains-dwelling animal, they browse more than graze, feeding in areas where shrubs and bushes provide the leaves they prefer and using their horns to bring twigs and branches into reach. They also consume certain fruits, large bulbs and tuberous roots.

1. You're enjoying a nice cold brew while waiting for the embers of your braai to burn themselves out. Between the mesmerizing effects of the brew, the fire, and the ambiance of the bush, you begin to count the cricket chirps as they perform their nocturnal symphony. You count 1,..2,..there are 54 chirps in 25 seconds.

You correctly conclude it's 32 degrees C and there will be no rain for your A.M. game drive.

2. The African grass owl, closely resembling the barn owl, is listed as a Vulnerable species. Your best chance of adding it to your list is to visit the sub-alpine grasslands of Lesotho.

3. A characteristic sign of a caracal kill is the dislocated neck of an impala who was chased into a tree.

1) FALSE - If i calculate this from your explanation on the insect quiz the
temperature would be 22 degrees.

2) FALSE - As far as i know you don't get them in Lesotho.

3) FALSE - This sounds too ridiculous to be true. :lol:

Well, the first two i have no idea about..

the 3rd one about the dislocated neck.
i heared that some predator has a habit of chasing their prey up a tree. not into but slamming into the tree and breaking their neck (dislocating it).

so for the 3rd one i would guess TRUE

No correct answer yet...(I'm not sure I can accept an answer to only one of the questions, but I sure would have liked that option in college!) Keep trying...

1. False ... agree on 22 (as per your formula).

2. False ... very limited distribution in Lesoto. I should rather go to Rietvlei in Pretoria.

3. False ... absolutely not! The best signature of a Caracal kill is teeth marks on the throat, and the victim being eaten from the inside of the back leg. Chasing a victim up a tree is absolutely a bad plan, especially since victims aren't stupid. It might happen accidentally, but only in very very few cases. Not a good hunting strategy for an animal that needs to survive on a daily basis.

So ... I'm in agreement with Siobain :wink:

I'll throw in my two bobs worth here:

a) False - As Siobain and Imberbe said, based on your formula I would go with the 22 C

b) False - Tyto Capensis is listed as Least Concern on the red list

c) False - I would go with Imberbe, but I would think caracal would only hunt impala fawn not full grown ones. Also, (and this is a question as much as anything) are'nt they also primarily bird hunters so a characteristic sign of a caracal kill would also be plucked feathers?

Looks like I'm the one who's going to learn something here, once again!

1. False, correct, just trying to get others to refer to some of the other quiz threads.

2. I read that the grass owl was listed as Vulnerable in the ""Eskom Red Data Book of Birds of S. Africa, Lesotho, and Swaziland", and also that it has become extinct in Lesotho, so I hope that has been proven incorrect, but the answer is False, as all of you said correctly.

3. This is where my answer differed from all of yours, so I will go with your answer of False, but I thought it was True based on the following:

In the Oct. 2008 issue of Africa Geographic, pg. 25, there was a photo of a caracal with an impala photo that includes the following paragraph: " Apart from the gnawed flesh on the hindquarters, a characteristic sign of a caracal kill, the carcass was unmarked when we discovered it. The neck, however, appeared to be dislocated, suggesting that the impala had been chased into a tree, breaking its neck - a common caracal hunting ploy."

This was part of a report of a census taken via camera trap at Mankwe Wildlife Reserve, by Jason Gilchrist, of Napier Univ., UK.
(Those wild 'n crazy funloving Brits, always pulling your leg!)

Anyway, I'll go with the unanimous vote of False, so Siobane....
you're IT.

Love these quizzes - I learn something new everyday I read here and with the diverse amount of information out there it is great to see the differing ideas come up.

Thanks guys!

A) The common Ostrich is capable of speeds of up to 70km's/h about
43 mph.

B) Less than 3% of bird species in 'Kruger' are abundant and very
common, whilst over 56% are uncommon, opportunistic or rare.

C) April is 'raptor breeding' season in 'Kruger'.

D) In the local 'Shangaan' traditions, thunderstorms are referred to as
'female rain', whilst softer rains are referred to as 'male rain'.
