 DESCRIPTION
  • White with a broad crest.
  • The underside of tail and wings are yellow.
  • Bill- blackish-horn colour.
  • Eyes black (reddish-brown iris in a mature female)
  • Length 45cm (18ins)

SEXING

  •  The Birds' are dimorphic (i.e. look the same or very similar). 
    •  so their sex can only be established by DNA Testing (feathers or blood) 
    •  Or Surgical Sexing (by an Avian Vet).
  •  Or by the Adult bird's eyes once they reach about two+ years old.
  •  Female will have reddish-brown iris. 
  •  Male the eyes are jet black.  
  •  Mature female has a smaller head and beak than the male.

GENERAL INFO

  • Umbrellas aren't particularly good at talking.
  • As a pet they need loads of constant attention.
  • Not a bird to be left on it's own all day - so if you work, this is not the bird for you!
  • They call them the "Velcro Bird" and that's exactly what they are like, very clingy.
  • Very loving but unpredictable when in "Breeding Mode".
     
  • NOT for the beginner  Breeder/ Bird-keeper or as a "First Pet Bird"!
     
  • They love to bathe.  It's lovely to watch them upside down with wings spread out 
    when there's a rain shower.


DISTRIBUTION

  • Mainly Indonesia.

HABITAT

  •  Forest, Open Woodland, Mangroves and Swamps.

AVICULTURE

  • Fairly noisy bird, initially shy. 
  • Quite a destructive bird, thin mesh is a Big "No No"  with these birds, they can chew thru. almost anything. 
  • Double, heavy-guage, parrot-proof wiring a must.  Esp. if you have other birds in an adjoining Aviary.

ACCOMMODATION

  •  Ideally, provide a spacious flight with shelter - 18 x 6 x 6 ft is an appropriate size.
  • Clean shavings and pieces of wood for them to chew are adequate for the nest box.

DIET

  • Good quality Parrot seed mix - not too many sunflower seeds.
  • They love monkey nuts. 
  • Walnuts are a special favourite but have to be halved for them, as they don't seem to be able to crack them open too well.
  •  Fruit and vegetables, love sweetcorn, peas and grated carrot mixed with egg food.
     
  • A calcium supplement, Daily essentials 3 + a Pro-biotic once a week.
  • Worming    x2 per year - spring b4 Breeding Season and Autumn after Breeding Season finished
    to prepare them for winter.
BREEDING
  • Usually begins in spring but can occur at other times of the year.
  • Breeding age starts around 4 - 5 years old. 
  • Hard wood nest box as ply wood won't last very long! 
  • A substantial Nest box size  : approx.15" square 30" high.
  • Clean shavings and pieces of wood for them to chew are adequate for them to create their own
    nest box base-bedding.
  • Chewing the wood helps to stimulate them into "Breeding mode".
     
  • CLUTCH :  is normally two eggs.
  • Both birds sit the eggs in turn and both parents feed the chicks.
  • Although, some do take longer to wean, they will beg for food for ages after they really need it.  
  • So, it's really a case of playing things by ear to make sure the babies don't suffer, physically or mentally.  
  • They should never move to a new home until they are fully independent.

Incubation -  28 days
Chicks Fledge - Around 14 weeks but still continue to be fed by the parents for weeks afterwards.
First moult   - Around 12 - 18 months old.

RINGING

  • Age:  Usually ring them about 2-3 weeks old.
  • Ring Size :  W (12.7mm)

HAND-REARING

  • Some Captive-bred, domesticated Umbrellas don't sit their eggs well and if this is the case then it's best if the eggs are removed and put in Incubators.
  • Some will sit and hatch the chicks but tend just to feed one of the chicks and the other one is left to
    starve and eventually die. 
  • Here is where Nest box cameras can help identify the problem before the either chick gets to stage
    where it is beyond help.
  • It must then be removed (carefully & safely) then hand-reared.
  • Rarely, altho. it can happen, the parents manage to successfully rear both chicks.
  • Often they may feed them happily and regularly up to 2 weeks but often not past 3 weeks. 
  • Keeping a close eye on them is the key and if the parents start leaving the Nest box for extended periods,
    • it's best to remove the chicks and hand-rear, as they can easily get chilled,
    • esp. if the weather is cold and they don't have their parents to keep them warm.
  • If a chick becomes chilled, it's metabolism slows down and it's feed response suffers
    • so then it does not "beg" for food and therefore the parents are not stimulated to feed it.
  • It's a catch 22 situation - this is why it's best to remove the chick(s).
  • Make sure you warm the chick(s) through by putting it in a pre-heated Brooder.
  • This will help save it's life and also speed up it's metabolic rate to help kick-start it's "feed response"
    when you start to feed it.
  • Some breeders are lucky and do have Umbrella pairs that will parent-raise their chicks.
     
  • A hand-reared baby would be ready at around sixteen weeks old to go to a new home.
