- The terms "pigeon" and "dove," especially in languages other than English,
- are often used interchangeably, with "dove" generally having connotations of
- grace, gentleness, and religious significance, rather than of speciation. In
- fact, pigeons and doves are representatives of several distinct genera of the
- subfamily Columbidae.
- Wild pigeons and doves are more or less worldwide in their distribution, with
- a number of species of each being native to North America. A few species
- such as the band tailed pigeon (Columba sasciata<) and the mourning dove
- (Sonaida macroura) are seen in parts of Canada (Goodwin, 1967).
- Domesticated pigeons (Columba livia domestica) and the common "street
- pigeons," which are feral derivatives of domestic pigeons, are not indigenous
- to the Americas, but were first brought to this continent by the French and
- the English, to Quebec and Nova Scotia respectively, circa 1607.
- All today's many varieties of domestic pigeons derive from the rock pigeon
- (rock dove) of Europe, Asia, and North Africa (Levi, 1969). The domesticated
- doves (Streptopelia risoria) Ringneck, Laughing, Barbary, etc., originated
- from a wild type North African ancestor (Streptopelia roseogrisea) and are not
- found in the feral state in the Americas (Goodwin, 1967). The number of dove breeders has increased considerably in recent years, particularly in the USA
- (Burger, 1974). Numerous research and zoological exhibit colonies are also
- maintained in both the USA and Canada (Kendall and Scanlon, 1981; Mulder,
- 1978).
THE BIRDS OF AFRICA REARED IN OUR BACKYARDS.
Monday, July 21, 2014
Abnormal behaviours such as stereotypies (e.g. route tracing) are frequently caused by an
understimulating environment. Experiments designed to study pigeons‟ cognitive abilities have
shown that they are capable of some quite complex thinking – for example, they can categorise
objects into groups in a similar way to humans – and they need a suitably stimulating environment.

Parasites:- can be a major cause of suffering for domestic pigeons. Effective ecto- and endo-
parasite control is essential. This involves removing faeces regularly, checking birds for parasites
regularly, and treating not only the birds but also their housing, as some ectoparasites such as red
mites do not live on the host when they are not feeding.
Aggression: – subordinate birds may be bullied and denied access to resources such as food,
water and perches. Monitoring birds carefully and making sure that there are sufficient resources
for all the birds to use them at once will help to prevent birds suffering through being bullied.
Ensuring that birds can escape from one another will also help to prevent stress and injury.
The following list of requirements is based on animal welfare science that has evaluated birds‟
references and motivation for resources, and on the ecology and behaviour of wild birds. More
information on pigeon welfare, housing and care can be found in the references listed at the end of
this document.
Social housing
Both wild Columba livia and feral pigeons occur in large, mixed flocks and so pigeons should be
group housed in the laboratory. Groups should be carefully observed when first set up to make
sure that aggressive birds do not bully or injure others. An „escape area‟ for timid birds will help to
avoid distress and injury. Breeding can be prevented by not providing nesting places, in which
case birds may lay eggs but will not incubate them.
Plenty of pen space
Pigeons should be housed in pens that permit enrichment and a range of behaviours, including
flight wherever possible – they have been shown to strongly prefer aviaries that allow them to fly.
Long, narrow pens are best because they permit short flights. Cages are not suitable for housing
pigeons and should only be used if there is compelling scientific or veterinary justification. If they
must be used, it is a good idea to use modified cages, for example rabbit cages with shelving,
perches and toys, rather than “standard” pigeon caging. Ideally, pigeons should be housed with outdoor access wherever possible or even in wholly outdoor flights, in which case they will need
access to covered shelters at all times.
Solid floor
Grid floors prevent foraging so are not suitable for housing pigeons. Solid flooring with litter
material for foraging is preferred. Daily cleaning and the use of minimal litter will help to reduce
levels of dust created by the birds.
Environmental enrichment
Pigeons have been found to benefit from items hung from chains, including bird bells, mirrors and
toys designed for other animals such as cats. For aviary housed birds, foliage attached to
enclosure sides using thick gardening wire can provide extra perching and shelter. Branches hung
from the roof and scaffolding will provide a more stimulating environment in very large enclosures.
Perches
Each bird should have access to a perching area and perches should be sited at a range of levels,
to encourage birds to establish territories and reduce competition. In larger aviaries, box perches
approximately 30 cm square and 15 cm deep located in blocks along one wall simulate a „natural‟
environment and help to keep faeces in one area.
Water baths
Pigeons splash considerably when they bathe, so placing water baths inside larger, waterproof
trays should reduce soaking. Extra baths can be offered to birds on the day before cleaning so that
any substrate and dust will be damped down. Pigeons also enjoy showers, although they must be
monitored to ensure that they do not become chilled.
A varied diet and opportunities to forage
Pigeons are omnivorous and should be offered a wide range of grains and green food,
supplemented with pelleted diets containing animal protein such as chick starter crumbs. Small seeds such as millet, rape or linseed can be fed on the pen floor to encourage foraging or by hand
to help habituate the birds to humans. Turf or trays with other litter can also be used to encourage
foraging, taking care to site foraging areas away from areas where birds defaecate. Other favourite
treats include pinhead oats, hemp with peanuts, popcorn and mealworms. Note that birds fed ad
lib all the time will become obese, especially if they are only allowed limited opportunities to
exercise.
10cm of feeder length per adult bird
This feeder length will allow all birds to feed simultaneously, which will facilitate natural behaviour
and reduce aggression.
‘Flight rooms’ where appropriate
If it is really not possible for pigeons to be housed in pens that are large enough for them to fly, an
alternative is allowing birds part-time access to „flight rooms‟ with perches (such as a spare animal
room), provided that they are closely monitored to prevent bullying. Birds can be trained to retreat
to nesting areas or even to fly to the hand, as an alternative to catching them with nets.
The domestic pigeon, Columba livia, is probably descended from the rock dove, which nests and
roosts on and in rock formations such as cliffs, gorges and caves. Feral pigeons living in towns are
escaped domesticated birds, and they use ledges on structures made by humans in the same way
that rock doves use natural rock formations. Free-living, feral birds can occur in numbers ranging
from pairs up to large, loose flocks that feed and roost together. However, the pigeon is highly
territorial and will defend roosting spaces and nesting areas. Pairs are usually monogamous and
males „drive‟ females away from the rest of the flock during the breeding season.
Domestic pigeons are primarily seed eaters but will take a wide range of grains, fruits, berries and
vegetation and invertebrates such as small snails. There are over 200 breeds of pigeon in which
different traits have been selected for racing or showing, some of which have traits that could result
in welfare problems. It is important to bear this in mind when choosing a breed for laboratory use.

A Kuroiler Chicken is a chicken breed with indigenous traits which grows faster and lays more eggs than the local chicken, this chicken breed has been introduced in Uganda. Kuroilers were first successfully introduced in India more than a decade ago. The birds are low-maintenance scavengers that thrive on household and agricultural waste.
How Kuroiler Birds Came to Uganda
The Kuroiler breed originated from Kegg Farms in India and is now available on the Uganda Market. “On July 12, 2010, the first Kuroiler chicks were hatched in Entebbe. On the same day, indigenous chicken were hatched,” says Dr. Daniel Ssemambo, the executive director of National Animal Genetic Resources Centre and Data Bank (NAGRC & DB). NAGRC & DB is an organisation, under the agriculture ministry, that supports the implementation of the national breeding policy.
According to Ssemambo, the first move was to find out how the Kuroilers faired against local breeds. “We hatched Kuroilers and local breeds on the same day,” he says. “The two breeds were given to chicken farmers in Kabale, Gulu, Apac, Mayuge and Wakiso districts under a pilot project to assess which variety performed better.
The farmers testified that the Kuroilers grew faster, putting on 1kg for hens and 1.5kg for cocks by three months and 3kg and 4kg respectively by six months.
Just like the local breeds, the Kuroilers are largely kept under a free range system, where the birds are left to scratch for food with no restrictions and very little or no supplements.
“The difference is that while the locals are moderate while scratching for food and may even take a rest, Kuroilers are aggressive and feed continiously. This explains why they put on weight faster than the local breeds,” says Esau Galukande, the NAGRC technical manager, who also took part in the research.
Kuroiler Birds on Uganda Farms
A farmer in Wakiso district said the birds grow faster, produce more and bigger eggs.
Compared to hybrids, the egg-yolk is even more yellowish, hence more nutritious. The fact that this farmer kept the chicken successfully in a semi-urban environment is a pointer to their big potential.
“I package the eggs in sets of half a dozen and sell them in supermarkets. A tray goes for sh10,000 compared to sh6,000 for hybrid eggs,” said Betty Ssewanyana, a farmer in Entebbe. Ssewanyana said while the mortality of local chicken is high, all the 23 Kuroiler chicken she got grew.
According to Dr. James Ongu, a veterinary officer from Apac, who undertook the development of the Kuroilers in the area, the growth and survival straits they exhibited against the local breed were high. “This area is largely chicken-producing and this breed is set to revolutionise and ease chicken rearing,” he said.
Asked if they could be crossed with indigenous chicken, Dr Vinod Kapur, from Kegg Farms said it was not advisable if a farmer wanted to maintain quality. Kapur said Kegg Farms would start distributing the chicken in Uganda.
Ssemambo said the chicken had a very big potential of improving nutrition in Uganda. The breed was launched in Kenya recently.
