Which lark are you referring to JJ? What other sources have you consulted? This is a very good question as JenB has said. I have a very extensive collection of bird books and it will be interesting to compare them.

It is the 3rd bird in the "Birding School for ducklings" - which has pink legs. I may be totally wrong of course :roll:
but the one in my Sasol book has Yellow legs and the ones in "Bird Pics" and "Niall's" site both have pink legs?
I do not have any other Bird Books with me at the moment just the Sasol(3rd edition) and that pic/drawing has Yellow legs?

Hope I have not confused you - but I don't want to name the bird as it is part of a quiz?

Thanks

JJ this is exactly the response I was hoping for :dance:
I might have been a little bit naughty in not specifying that the bird was seen in the Mallelane region of Kruger :twisted: This might just have an influence on the id
The fact that you are looking at the smaller details like leg colour is half the battle won :thumbs_up:

Looking at the bright side is that after this session of the quiz you will never forget this brown feathered birdie again

Or I need new glasses (probably) or we are looking at two different birds :?

Thanks Sparks - since the bird I am looking at is the wrong answer in the quiz, I can name the one where the colour of the legs are different. :shock: I will start searching again :slap:

The Melodious Lark has YELLOW legs in my SASOL Book, but on "Bird Pics" & "Nialls" website the Melodious Lark has distinct PINK legs (not sure if it is the "light/time of day" that is responsible?) for such a difference in colour (YELLOW to PINK) :hmz:

That is a very good question JJ :wink:

My personal opinion is that you will find slight differences between books such as Sasol, Roberts and Newmans because you have, on certain species like larks, pipits and cisticola's, artists and writers own experience and interpretations on certain species..

If they felt that the legs to them looked more yellow than pinkish, then they will highlight that fact. I don't have my Sasol here now and would love to go have a look at it. In Roberts it is indicated as pink/fleshy colour and is also illustrated like this in the drawing and description.

Will go have a look at it tonight and see how Sasol shows it. :D

This is something that is raised many times especially when it comes to pipits especially, where people generally tend to rely on the pink/yellow aspect to differentiate between the various confusing species in this exceptional difficult family of birds.

Experts like Faansie Peacock actually advised people not too rely solely on this feature. Because blood flow to the limbs and bill can and will drastically alter the coloration of it.

Not only does blood flow alter the coloration, but so too does sunlight. A classic example of this can be seen with Indigobirds. We encountered many Indigobirds during the BBW up in Punda, 2 weekends ago and in a group of 10 people we never had a unanimous vote amongst us as to the identity of an Indigobird. The light and blood flow to the limbs altered the colour so much that the whole group of 10 birders had different opinions on the coloration and thus identity of the bird in question.

My advice to you is simple. Follow Faansie's advice and do not rely heavily on the yellow/pink colour differentiation. When it comes to light and dark colours it is a completely different story and one would then rely on that, but the pink/yellow scenario is not foolproof.

Hence the reason why books and other sources differ from each other when it comes to this issue.

Hopes this answers your question.

Thanks for the Q, JJ. I've been wondering that for many years myself, and now we can hear from the experts. :thumbs_up:

Oh dear, I struggle with any bird book when it come to colour :hmz:

That's why I have:
Bushchickens
Little brown jobs
Big Brown jobs
Water birds
Birds at water
pesky pigeons

then there are my perenial favourite... the.. "I wish I had a bigger lens jobs".
The bird doesn't sing because it has answers, it sings because it has a song.

A classic example is African harrier-hawk... it can change the colour of its facial skin from yellow to bright pink in a matter of minutes, depending on the level of excitement... The same thing can be seen to some degree in humans, most spectacularly so in light-skinned / blonde people... Their skin colour can range from pale (in shock) to near purple (embarrassed or angry).

Always use as many features as possible to substantiate your ID-call (Facial pattern, giss, size, bill shape, distribution, habitat, sound/song/call, patterns and coloration in the plumage, specifically the primary flight feathers and retrices, even its habits - like tail-wagging, and colour of bare parts. Having the bird in the hand - like birdringers often have the privilege to do - allows exact measurements to be taken that conclusively will confirm an ID). Never base an ID call solely on the colour of the bare parts of a bird.

Thanks everyone for advice - It would be nice to have a whole lot of features to ID from, but the quiz only gives a photo :whistle:
