Hi dance4rain,
Since my reply to your question about fruits in Myth and Fact is quite lengthy, it might better to present it as topic by itself. Hope you don't mind. It will allow further discussions to be clearer , rather than have it jumbled up with answers to your other questions.
Here goes:
Puteh Food - Too Much Fruits?
I did write about this earlier but perhaps I would repeat it here as it is a very common misconception.
I believe that most forumers would agree with the logic that as birdkeepers or even if you are keeping other animals (dogs, cats, fish etc) you would try to provide the animal with food which is its natural diet. Of course now we have dog biscuits for dogs, cat food for cats and so on. But even such commercial preparation always advertise themselves on the fact that it's ingredients are very close to natural food.
The same applies to birds. Why do people take the trouble to catch grasshoppers or pay for crickets which are troublesome noisy insects, to feed their birds? Again its simply that we wish to feed our birds with the closest substitute to their natural diet.
Any experienced birdwatcher will tell you that the Mata Puteh's natural diet consist mainly of four things: nectar, fruits, grubs (and small caterpillars) and small insects (including small spiders).
Most of us will feed our Putehs with commercial pellets and supplement it with fresh fruits. The question is whether we are giving the Puteh too much fruits. The answer is simply: No.
An animal such as a bird (or any other animal except Carp) eats only what is necessary and never overeats. So you may stick a whole apple or orange inside the cage, but the Puteh will not gorge itself to death, instead it will peck only a small portion of it. The only harm is that its a waste to put an entire orange or apple in the cage. If anyone tells you that his Mata Puteh ate an entire apple in one day - its either he is joking or he is delusional.
What does it mean if my Puteh has watery faeces?
If you, the birdkeeper, has watery (or soft) faeces, then there is cause for worry; but a Puteh's faeces is expected to be watery since its natural diet consist largely of liquid & soft food - nectar and fruits. If your Puteh's faeces is hard - you should be worried.
Remember this: the Puteh's diet, apart from nectar and fruits, also comprise of small juicy insects and grubs; all of which are soft food. Squash a caterpillar and you will agree with me.
So how did this 'fact' about too much fruits come about? The old timers tend to equate their pet birds' faeces with the human variety - and that is incorrect.
If you have ever kept a finch which is a pure seed eater and supplemented with some green leafy vegetable, you would immediately notice two things - first is the finch's faeces is not watery and the second is the perch sticks are sticky. The faeces are not watery because the seeds provide lots of roughage. The perch sticks are sticky because some of the seeds are high in carbohydrates.
If you feed the Puteh with waterchestnut, its faeces will be firm/dry as noted by Sunny. I would like to add that the bird's faeces are firm/dry is simply due to the fact that waterchestnut is fibrous. Next time when you eat waterchestnuts, take time to note how it feels when you keep chewing on it for a full minute or more - the waterchestnut mash still feels solid. Compare it to say a bite of apple or papaya - it would be all mushy gooey in less than a minute. Naturally when the bird is fed with waterchestnut, you can expect with 100% certainty that its droppings will be 'dry' or firm.
(Note about papayas: The papaya fruit has laxative qualities. The most active laxative part of the fruit is the white pimply surface in the center where the seeds are found. So naturally, you will notice an increase in defaecation when you feed your Puteh with papayas.)
In the case of oranges you will actually see the orange rind in the faeces, whereas the waterchestnut fibre is more fine and hence not quite so obvious. But why is the faeces 'dry' in the case of waterchestnut and wet in the case of oranges? The answer is simply that oranges have a higher liquid content.
What about too much oranges and the Puteh's faces is yellowish wet. Wet, as I said before, is due to the high water content of the orange fruit. The colouring is due to the orange itself. The bird's digestive system will only absorb the vitamins, minerals, the fructose (sugar) and pass out the rest. The same applies to apples and papayas. In the case of apples the faeces will be brownish wet. The brown colour is due to natural discolouration of a cut apple exposed to air and in this case the apple has in fact been through an added process in the bird's digestive system which of course will be passed out brown in colour.
Too much fruits will lower the bird's 'api' is another common belief. Not true. How could that be when in its natural environment the Puteh is in constant search for fruits and nectar, its natural diet?
In fact now is the Mata Puteh's high season. The rains have started. Take a Saturday off on your won and observe them in the wild. The insects are out in full force, escpecially after the rain stops. The Mata Putehs will have a feast. The protein and calcium supplement from the insects helps them to prepare for breeding and to feed its hatchlings.
Another common belief is feeding the Puteh with too much insects, mealworms and grubs is bad. Maybe true. Insects and other such stuff are the Puteh's source of protein and calcium. Too much protein may cause some problems for the bird. Its tiny liver will not be able to cope. But as I said earlier, the Puteh eats only what is necessary, so is there any worry that it might overeat insects and such? Yes, especially when you do not provide it with enough fruits, pellets, and nectar, then the Puteh has no choice but to eat more of the insects you give it.
So why is it that the Puteh's basic diet is nectar and fruits?
If you have kept or are keeping different species of birds and if you have observed birds in the wild, you will note two basic differences in the behaviour of birds. Some birds are more active and some are less active.
(Group A) Examples of Active birds: Mata Putehs, Jambuls (and other bulbuls), finches, leaf birds
(GroupB) Examples of less Active birds: Owls, Eagles, Merboks, Tekukurs, Shrikes
The birds in group A are more active and they expend their energy quicker. They need high energy food such as nectar/pollen and fruits (which has lots of fructose). The finches, say a Grey finch, does not eat fruits (some do, if you condition them) but the finch eats far more seeds than a Merbok would in terms of their body weight ratio.
The birds in Group B are less active. Have you ever seen an owl jumping here and there or flying all over the place? Merboks are only active when they are looking for seeds, otherwise they will be happy to perch on their favourite branch and relax. Same with the tekukur. Eagles and shrikes are the same. But someone did ask me during a birding a trip why I said that the eagle is less active than a bulbul when it is common to see eagles soaring around in the sky ?
Yes, you do see eagles soaring in the sky, but they don't actually flap their wings constantly to keep flying, do they? No. They actually rely on the warm thermal air which rises up and they 'ride' or glide on the thermal. Minimal energy expended. The only effort required is when they launch themselves off a tall tree or cliff, flap their wings for a short while and catch the thermal. Then they will simply glide or ride the rising warm air.
The owl sits patiently on a perch and watches for its prey. The only time it flies is to glide down silently to pounce on the rodent and fly back to its nest or perch.
The same can be said of herons or bitterns. They stay still most of the time in the swamp and move to strike only when it spots a fish or when it wants to walk over to another place. Not much energy used.
On the other hand, the Group A birds never stay still in one spot. Even when in a cage, the Puteh and the bulbul will jump and down from one stick to another. In the wild, they are even more active. Most times you can't even get your camera up in time to aim, focus and shoot, unless it is feeding. Of course now with a digital camera, you simply don't worry about film wastage and just tembak, you are bound to get a good shot.
So, do you now realize that the birds in Group A are mostly frugivores-insectivores and the birds in Group B are carniverous? Thats why, feeding your Puteh with fruits and nectar is never bad for its health - in fact its good.
In some major fruit producing countries, such as Australia, New Zealand and in some African countries, the Mata Putehs are treated as pests as the birds spoil quite alot of the fruits in the orchards. Persimmons are an all time favourite.
Thus in the wild the Puteh's diet is naturally more nectar and fruits and less of the insects and such stuff. Nectar and fruits are widely available and the fruits and flowers don't jump, fly away like the insects or camouflage itself like the caterpillars. So the basic diet of a Puteh is fruits and nectar. Insects and grubs are supplements, which are necessary but need to be controlled.
If your merboks faeces are wet there are only two reasons - diarrhea and the other is the bird is drinking lots of water. The latter is harmless. But you might need to treat the former. Treatment - crush (better still, to blend) some tender jambu leaves, roll it into tiny balls and force feed one or two balls to the merbok. Second give it black Chinese tea.
Merboks faeces should not be wet, they are bascially seed eaters and nothing else.
However if your Puteh's faeces are dry (dry as in the case of merboks), then your Puteh has a problem. Its either not having enough fruits or its not drinking enough water. Take some time to observe your Puteh when it eats the pellets - invariably, it will sip some water after eating the pellet. Liquid - whether water or nectar or fruit juice (from the fruits its eats) is a very important part of its diet. So do expect watery droppings or at minimum, soft droppings from your Puteh.
I feed my Putehs and Jambul with nectar, slices of fruits and pellets. Fruits are apples, oranges and papayas. Their droppings are mostly wet.
They are active all the time. Sing their middle tones, buka in the morning, late afternoon, and when it rains (or when I shower). No problem. The only problem is - sometimes they sing so sweetly - I am reluctant to release them back into the aviary to join the other putehs.
Thanks for reading. Constructive comments and correction of any misrepresentation of facts are welcome.
