Red-rumped Parrot Psephotus haematonutus

Other names: Grass Parrot, Grassie

The Red-rumped Parrot is an ideal bird for the beginner, there is no experience needed. There is no specified diet required and the noise level is low. Many mutations have occurred and this make the bird ideal for showing. The Red-rumped Parrot is extremely hardy and can be kept under varying weather conditions. 

 

Description and sexing: 

Length of male 28 cm average, female usually smaller. Average weight 69 g, female usually lighter. The sexing of Red-rumped Parrot is obvious, the male is a green bird with blue suffusion and a prominent red-rump whereas the female is a greenish-brown bird without the red rump.

Behaviar and keeping:

Red-rumped Parrots are easy to keep, however they are aggressive to the same species and best is to keep them a pair in one aviary. Flock breeding is possible (only with larger parrots) but keep an eye on them and if possible should be prevented. Feed a seed diet, French white millet, canary seed, grey striped sunflower seed and hulled oats and occasional green feed during the non-breeding season. 

Breeding:

Most Red-rump Parrots are flexible as far as nesting facilities and if it suits them they will breed. They will breed two clutches, with an average of four to six eggs, during May and January. Incubation last 20-25 days and all young hatches within a 48-hour period. The band size is 5mm.

Mutations:

Sex-linked mutations:

Cinnamon, this mutation alters the color of the eumelanin into brown instead of black. The result is a brownish yellow bird with brown flights and pink colored legs and toes. The red rump stays unaltered. Typical for this mutation is that all youngsters have red eyes at hatching. The eyes darken to dark brown after about 8 days.

Lutino, the lutino factor reduces visible eumelanin completely. Combined with a green bird this will result in a pure yellow bird, the legs are pink colored and, typical for this mutation, red eyes. The color of the rump is red end stays unaltered. 

Red Rumped Opaline

Opaline, 

Red Rumped Lacewing

Cinnamon-lutino (crossing over), Originated by crossing-over between cinnamon and lutino, also know as “lacewing”. In the green series these birds are yellow with a grey mask and red eyes, a red rump and the flight feathers are light brown. The chance on crossing-over between cinnamon and ino is 3%.

Recessive mutations:

Red Rumped Blue and Albino

Blue, the psittacine is completely missing in all feathers. The result is a blue bird with a white belly and white rump. This mutation never affects the color of the paws, nails and eyes. Blue combined with a Lutino bird will produce Albino's as shown on the photo. 

Red Rumped Aqua and Aqua Cinnamon

Aqua (Par-Blue),in an aqua bird the yellow psittacin is reduced by approximately 50%. That means that the yellow colour in the cortex of the plumage is not as yellow as it is in the wild type. If we dilute yellow paint for about 50% we will also obtain a lighter yellow colour.  The blue light rays, aroused in the spongy zone, pass through a light yellow “filter” producing a colour that is not green and not blue, it is more in between. The feather structure of this mutation is very poor, often resulting in damaged feathers as the photos show (note, these bird in the photos are in "top condition" more often you find them in worse state). 

Red Rumped Pied

 

 

recessive Pied (Olive Pied), We might say that this type of pied causes a 80% absence of eumelanin. The color of the flight feathers, legs, toes and nails can vary from grey till completely dilute. In most cases the rump color is totally affected and the normal green color is changed into olive green. Note, the visual difference between male and female is gone, both look the same. Although, sometime the male is slightly more intense in yellow color. 

Red Rumped Orange

Orange, Trough selection it is possible to breed totally red/ orange Red Rumped parakeets, especially combined with an Opaline bird gives a nice result. 

Red Rumped Pale Fallow Aqua Pale Fallow

Pale fallow, an advanced fallow mutation used to named recessive Lutino, this is wrong. An yellowish bird with a red rump and ruby red eyes. Clear red eyes are typical for this type of fallow. The Legs, toes and nails are pink colored. They look at like Cinnamons split for Lutino, the difference between both mutations is the lacking of the pupil of the fallow mutation. Also note, do not keep the fallow in full sun as they have poor eye sight and cannot filter the light as normal birds can. 

Red Rumped Bronze Fallow

Bronze fallow, in common it is of a somewhat lighter shade than cinnamon caused by smaller eumelanin granules produced by this mutation. These birds have pink legs and red eyes. At first sight this bird can be mistaken for a cinnamon, however, the clear red eyes and the paler back of the head indicate the typical fallow mutation. 

Dominant mutations:

Red Rumped Pied

Pied, the result is a bird with unpigmented patches or areas. First bred in Australia. This type of pied can vary from a few pied feathers till an almost complete absence of eumelanin. Although these birds have a dominant inheritance, it is hard to say whether there is a clear difference between SF and DF birds or not. Unlike recessive pied there is visual difference between male and female in appearance.  

Red Rumped Grey and Grey Blue Opaline

Grey-green, these birds display a different color which was first described as steel blue. In this mutant the refractive index of the keratin seems to be altered by the mutation. Normally the keratin has a “milky” appearance, however, in this mutation it actually appears to be completely transparent. The result is a slaty colored bird in the blue series. 

Red Rumped Blue and Cobalt

Cobalt, this is a new mutation, I am not sure if it is a true Cobalt like in the Lovebirds. The feather structure of this mutation is very poor and similar to the Aqua birds. Note, there not related, a Cobalt bird combined with Aqua produces green birds. The best result is to breed with normal blue birds and hopefully through selection the feather structure will be better. The photo is showing a normal blue compared with Cobalt.
