The Husbandry of Fairy-wrens

The
pros and cons of keeping Fairy-wren's
Pros:
-
They
are active all day - whereas parrots don't move and finches
disappear; wrens are out in open view and are always nosey.
-
They
are easy to feed; at least relative to such birds as lorikeets
and fruit pigeons, if you set the aviaries up correctly to start
with.
-
Wrens
breed readily given the right conditions and are easily sexed,
at least as adults.
Cons:
-
Young
birds are not easy to sex until they are about three months
of age, depending on the species.
-
You
need a special permit and birds are therefore more difficult
to buy or sell.
-
Wren's
must be fed daily-without fail
Generally
speaking wrens are a fascinating and attractive challenge to aviculturists
of all standards.
So what do you do if you think you want to keep wrens?
| Rule
No 1: "With wrens preparation is everything - do not
buy in haste before you are ready." |
Setting up an aviary to cater for their needs.
1. Size
As large as you can provide with a minimum size of
5' by 10' by 7'. The
smaller the aviary the less temptation there is add other birds.
But if the aviary is too small it is not suitable for wrens
either. It is very
important to keep only one pair per aviary and to avoid keeping
wrens in adjoining aviaries. My Splendid Fairy-wrens are kept in
a 12' by 18' aviary with Diamond Fire-tails, Cubans, Cordons, Double-bars,
Gouldians and quail. All
species except the Cordons have bred. However, in a 5' by 10' aviary I have had no success breeding
wrens when any other birds were in the aviary; but on their own
they bred very well.
2. Floor
A mulch of some description is useful to attract
insects. I add a catcher
full of leafy grass clippings as often as possible and fork it over
every month or so.
3. Plants
Plants serve three different purposes in wren aviaries.
(a)
Provide cover
and nest sites. Plants useful for this purpose include Needle-Brush,
Bamboo, Book Pine and etc. - any thing thick but manageable will
do but take care that it doesn't start growing out the top of the
aviary and breaking the wire.
(b)
Attract insects. I use Hibiscus and Roses for aphids.
(c)
Bathing.
A fine leafed hanging baskets or two under the mist spray
gives great enjoyment to both you and your birds - I use Asparagus
Ferns.
4.
Mist Sprays
As well as watering the plants in the aviaries mist
sprays encourage insects breeding by keeping the mulch moist.
5. Lights
I use 12 volt garden lights on a timer to extend daylight
hours. During the night
moths are attracted to the light, and disperse into the foliage,
to be found the next day by the hunting wrens.
6. Water
Water should be provided in a shallow dish placed in the
shade. I find a of water depth of approximately 1" is suitable.
Wrens do not spend much time at the water-bowl because they
prefer to drink and bathe in the shrubs.
7. Feed Stations
Feed stations should be placed near the door, whether it
is at the front or the back of the aviary.
You should try to stay out of their space as much as possible
as privacy and secrecy is very important to these birds.
The mealworms must be shaded as direct sunlight (or even
heat on a warm day) will kill them very quickly and wrens will not
eat dead mealworms.
|
Rule
No 2: "Check carefully that there are no holes in
the aviary. Wrens
cover every inch of the aviary several times in the space
of the day and will find even the smallest hole very quickly."
|
Feeding
1. Mealworms.
These form the staple live food for wrens and therefore
you need in active colony - I don't mean just one box, I mean at
least six to eight boxes PLUS a reliable source for purchasing in
quantity at times when yours are not breeding fast enough.
My basic diet is one tea spoon of mealworms per day per bird.
2. Softfood
Mix
My recipe is one egg, mixed with one tablespoons of each
of the following Insectivore Mix, egg biscuit and grated cheese.
This is an easy mix to make and keeps well in the refrigerator
in a sealed container for a week or two. I feed this mixture at
the rate of one desert spoon per pair per day.
The wrens don't eat a lot of the mix, but it is a reliable
back up to mealworms and any quail you have will love the left-overs.
3. Insect
Bucket
Citrus fruits, watermelon and tomatoes are some of the
best ingredients for the insect bucket.
However any compostable material will suffice. This source of live food is very important in a breeding season
because newly hatched chicks need to be fed very small live food.
Plus all the wild live food generated by the mulch, plants
and lights.
Now you can get your birds!
The Wedding Day
This is when you introduce the birds to the aviary and
to each other. This
is best done out of the breeding season and when the birds are out
of colour. You should
observe the birds carefully to detect any bullying or excessive
aggression. Fully coloured
birds must be watched extremely carefully (even birds bought as
a mated pair placed in a new aviary can become aggressive).
A friendly game of chase is normal behaviour but the bird
being changed, usually the hen, is always in control and when she
stops the game should be over and neither bird should look distressed
at any time. Make sure both birds are seen at the mealworm dish
within the first hour. If
you are not happy, catch them up, and keep them separate until the
next day. Then you should place than in adjoining budgie cages in
the aviary for a few hours before releasing them at the same time
- the next morning you will know if this has worked!
The Breeding Season
|
Rule
No 3: "Hen birds must be rung, either above the ankle
or above the knee as young birds will rapidly grow up
to resemble their mothers."
|
Nesting Material
Some
pairs will use of variety of material but others are fussier.
I have had nests made entirely of under-felt; a ball of fluff
5 inches in diameter with just a few white feathers in the nest
chamber.
Feeding
As much variety as possible.
Mealworms of all sizes must be provided (not just the big
ones) plus fly pupae, vinegar flies and moths if available.
The mealworm dish must never be empty, especially at daybreak.
Remember that hot weather will kill mealworms very quickly so worms
must be fed as a constant supply throughout the day. Warning:
mealworm consumption can increase from a teaspoon per day to a teaspoon
per hour if the nest contains multiple chicks!
If everything is to their satisfaction wrens can breed
continuously from November to April - laying a new clutch of eggs
as the previous young leave the nest.
If conditions are not right, wrens will often try hard to
breed but will continue to fail.
My Superb Fairy-wrens have bred from July 95 to February
98. In their best year
(1996) they had 13 young.
The Splendid Fairy-wrens started breeding in April 96; their
best year was 1999 when they had 4 chicks.
When to separate the young? The answer is "not too soon but not too late" and
varies with each pair. Birds
should be watched carefully for any aggression developing towards
the young birds and also to ensure that they are no longer reliant
on their parents for food when they are removed.
Conclusion
Wrens are very active and attractive birds with a lot of
personality. They are
easy to keep if you take the time to set up both the aviary and
your food supply correctly, but you must be willing to feed them
at least once a day, every day.
With the investment of a bit more time and trouble to provide
a more varied supply of live food, wrens can be bred quite readily
and often very successfully.
Research into the birds you are interested in is very important
and, as there is very little written material available, you should
talk to as many people that keep wrens as possible.
A good source of talkative wren keepers is the Softbill,
Dove & Quail Branch of the Society, so I invite you to come
along to a meeting (for further information please check out the
Branch section).
