For Disease Prevention and Traceability in Queensland
A Code developed under the auspices of the Aviary Birds Biosecurity Reference Group, Queensland.
- This Code of Practice applies to private keepers of aviary birds in Queensland which includes pigeons and doves, finches and softbills, canaries, quail, parrots, pheasant, waterfowl and other avian species that are kept purely as ornamental birds and that are not farmed to produce food for human consumption as in a commercial enterprise. Requirements for commercial enterprises and public avian collections are specifically covered under other legislation.
- Biosecurity measures are a series of steps that should be taken to prevent the entry, proliferation and spread of exotic organisms (animals, plants, pathogens) which may impact the health and productivity of Australia’s community, industries or environment. In relation to this Code of Practice (COP) for aviary birds the key focus is the emergence, proliferation and spread of pathogens causing disease of avian species, some of which may be zoonotic and have public health risks or be of commercial significance for other industries. However, the COP seeks to establish a series of best practice actions which can assist aviculturists to recognise and manage disease threats whether they are endemic (already present in Australia) or exotic (not yet present in Australia) disease threats.
- This Aviary Birds Biosecurity Code of Practice for Disease Prevention and Traceability is intended to be read in conjunction with the ‘Code of Practice – Aviculture’ already established in Queensland. The ‘Code of Practice – Aviculture’ specifies design and construction methods for cages and aviaries, recommended densities and feed and water requirements to ensure appropriate housing and keeping of aviary birds and to minimise the risk of escape of aviary birds to the environment.
- Taken together, the Code of Practice – Aviculture and this Biosecurity Code of Practice provide a valuable guide to effective husbandry and welfare requirements necessary to maintain healthy populations of aviary birds in Queensland.
Key elements of the Code
1. Prevent wild birds having contact with your aviaries.
Wild birds can be reservoir hosts for a wide range of diseases and parasites which can affect aviary birds. Pathogens or parasites can spread from wild birds via droppings contaminating water sources within aviaries or through contamination of aviary floors. In both cases pathogens or parasites may spread to aviary inhabitants through direct ingestion or through intermediate organisms such as insects.
Wild birds will be attracted to your aviaries or their vicinity for the following reasons: o the prospect of obtaining food on a regular basis;
o similar or related species attracted to their own kind;
o predators attempting to attack your birds;
- Wild birds must be prevented from direct contact with your birds. Selecting a mesh that will exclude the entry of small birds (finches or sparrows) needs to be considered when housing larger birds like cockatoos or pheasants and even if birds are basically flightless all aviary enclosures should be fully covered by mesh and not open to the sky
- Do not attract wild birds or other vermin to feed on discarded bird-food waste near your aviaries. Discarded foodstuffs should be disposed of as with household garbage.
- Ensure water sources within aviaries are protected from external faecal contamination.
o Water receptacles within aviaries should be positioned within the covered shelter section or should have a cover to exclude direct contamination by droppings from outside the aviary.
o Consideration should be given to flights being fully-roofed to prevent wild birds defecating into the aviary, but this should be balanced against the need for access to sunlight for the birds and plants in the aviary. Flights can be covered using translucent polycarbonate roofing while still allowing-in sufficient light.
o It is preferable to use reticulated town water if available. If roof collected rainwater or stream/ river water must be used consider whether this should be treated or filtered before use
o Waterfowl species that require access to water should be provided with ponds within a netting-covered area.
Water quality in such ponds needs to be monitored.
Wild birds should be discouraged from perching on or above you aviaries. Wild birds that defecate, preen or interact with your birds while perched on or above your aviaries can spread disease, lice and louse-flies. This risk can be reduced by:
o Not having overhanging trees above your aviaries
o Nylon bird netting or orchard hail netting erected as an outer barrier over aviaries.
Electric fencing mounted on top of aviaries to repel wild birds. o positioning smaller aviaries within a larger shed
Keep your aviaries, cages, feeding equipment and other implements clean and dry.
- Aviaries and bird-related equipment need to be constructed so that cleaning and disinfection is made easy. The more complicated the design the harder it is to clean.
- Aviaries should be designed such that floors are well drained and do not retain excessive moisture which might encourage disease organisms and parasites.
- Aviaries with “earthen” floors could have agricultural drainage pipe installed beneath the surface to remove excess water or could be covered with a 5-10 cm layer of coarse sand or gravel to facilitate rapid drainage.
- Floors should be raked and cleaned regularly to remove accumulated droppings and the whole surface layer should be changed or freshened annually.
- High-pressure water cleaners should be used to regularly clean concrete floors.
- Feed and water containers should be washed regularly using household dishwashing detergent and disinfectant. Ideally bird-keepers should have multiple sets of feeders to allow this.
- Don’t share carry cages or bird-keeping equipment with other bird or poultry-keepers unless it has been thoroughly cleaned and disinfected.
- Clean any second-hand equipment before use. If second-hand or borrowed bird-handling equipment cannot be disinfected you should not use it.Limit visitors to your aviaries and birdsHuman visitors can carry disease organisms from one bird collection to another through dirt attached to footwear or clothing. To reduce this risk the following points will assist:
- Restrict visitor access to the interior of your private aviaries, especially people you don’t know.
- Satisfy yourself that visitors are wearing clean dust-free clothing and footwear if they are bird or poultry keepers.
- If you regularly allow visitors to enter your aviaries or attached buildings such as feed sheds, walkways, incubator rooms, nurseries or have large numbers of visitors participating in an aviary visit you should install foot-baths containing an appropriate disinfectant at the entrance and require it’s use;
- Keep a record of visitors. It is reasonable to collect basic details or even to ask to see identification of any person visiting your private property. This is valuable for security as well as biosecurity;
- For large collections consider the installation of security cameras including those that are movement-activated.
- Visitors should not bring birds into your aviaries or buildings where your birds are housed or where your bird’s food is prepared or stored unless those birds are being transferred to you, in which case quarantine measures (outlined below) should be implemented.Quarantine all new birds – isolation, observation, medicationQuarantining of all new birds which enter your premises, whether obtained privately or through a public bird sale or pet shop, is one of the most effective biosecurity measures you can take.
- Always source your birds from a reputable seller or breeder whose bird-health and sanitation standards are known;
- Always buy healthy-looking birds and if possible conduct a physical inspection of the bird;
- A pre-sale inspection by a veterinarian experienced with birds could be warranted in some cases, If this can’t be done, a post-purchase examination could be obtained, along with a guarantee from the seller that the bird can be returned if problems are found.
- If purchasing new birds you must quarantine those birds geographically and managerially from your existing collection by isolating them for at least 30 days;
- Establish a specific quarantine cage or small aviary in a quiet stress-free area geographically isolated from your collection and ensure that all cages, water and feed receptacles and other items used in the quarantine area are NOT used for any other purpose with your bird collection
- Thoroughly clean and disinfect all cages, water and feed receptacles and other items used in the quarantine area after a set of birds leaves quarantine.
- Maintain close observation of the new bird(s) noting any signs of illness;
- Feed and service quarantined birds AFTER you have tended to your other birds. Always wash your hands using an alcoholic hand wash before and after attending to quarantined birds;
- While in quarantine consider administering a treatment regime to deal with possible parasite or pathogen infections, ensuring that all medications are administered in strict accordance with directions for that product.Know the signs of diseaseWith birds in your private collection and birds held in quarantine it is valuable to be able to identify the signs of disease and know how to respond. Obvious symptoms which indicate ill-health include:
- swollen heads, bulging or dull eyes;
- fluffed feathers, feather loss (the latter may indicate behavioural problems rather than disease)
- Respiratory distress, laboured breathing indicated by tail-bobbing;
- Diarrhoea, soiled vent area;
- Discharge from the mouth, nose eyes or cloaca often indicates disease
- Loss of appetite, difficulty in feeding, vomiting,Loss of pectoral muscle mass, which can usually only be determined by handling the bird. A prominent sternum(keel bone) suggests loss of condition and may be related to the expression of disease or a poor diet;
- Sudden illness and death of several or more birds;
- Reluctance to move, eat or drink;
- Poor feather condition may indicate that the bird is too ill to preen;
- Inability to walk, stand or loss of balance (especially in ground-dwelling birds);
- Unusual head or neck posture. Seek advice on how to respond to these signs of ill-health through authoritative books, other experienced aviculturists or by consulting a qualified avian veterinarian (see http://www.aavac.com.au/). After handling any birds (whether ill or not) or handling second-hand equipment you should wash/disinfect your hands immediately.
- Unwanted Aviary BirdsUnwanted aviary birds should NEVER be released into the wild. This constitutes animal cruelty under Queensland’s animal welfare legislation and will almost certainly result in the death of the bird by starvation, or being hunted to death by predators. Unwanted aviary birds should be offered to other bird owners, animal welfare organisations, bird clubs, or vets, all of which can attempt to re-home the birds. Contact your club or the Queensland Council of Bird Societies.
- Actions for Organisers, Exhibitors and Vendors at Bird Shows, Sales, Auctions and MarketsThere are a few simple steps that organisers and exhibitors involved with bird events, where live birds are exhibited in competition or sold, can undertake to help prevent the spread of disease. Events such shows and sales where large numbers of birds from different sources come together in one venue represents a significant risk in the event of disease. With the exception of fancy pigeons Columbia livia, aviary or ‘caged’ birds at shows are not handled by the judge which removes one pathway for cross contamination between birds.
Event organisers, bird clubs and show societies should:
o Strictly apply bird-health and sanitary standards for all birds at the venue
o Strongly consider having a qualified veterinarian or similarly experienced person inspect all birds entered for a show or sale event. In the case of multi-day shows ensuring that a veterinarian is contactable by telephone is advisable.
o Exercise their right to refuse entry for any bird deemed to be in ill-health or injured.
o Keep a record of all vendors and exhibitors. In the case of sales it is advisable to also collect contact details of all purchasers where this is possible. Noting that it is the responsibility of each individual bird owner to know the origin of all birds they buy or have in their possession.
o Retain contact information confidentially and securely for a period of 12 months after the event (when it should then be destroyed) to aid with traceability in the event of an outbreak of an avian disease and to assist in an emergency response if infected birds were present at the event.
o Hand washing facilities should be accessible, or hand-sanitising products available, so that everyone in the venue is able to regularly wash or disinfect their hands and they should be encouraged to do so;
o Ensure that waterfowl and poultry are not be in the same area as aviary/cage birds and pigeons;
o Advertise and enforce that members of the public are not allowed to bring pet birds (e.g. uncaged or on a harness), or other animals to a public bird sale. This presents a danger of disease spread throughout the venue and threatens the health of the vendors’ birds. Exhibitors or vendors should:
o Not take any birds to a show or sale if there are signs of illness in their collection;
o Ensure their bird equipment, carry boxes, crates, transport containers and feed and water containers are cleaned and disinfected before and after a sale or show;
o Avoid handling birds other than their own, but if this is necessary it is advisable to regularly wash or disinfect their hands;
o Disinfect their hands after placing sold birds into the buyer’s transport boxes to minimise possible cross contamination.
o When returning their own birds home again seriously consider a period of quarantine before re- introduction to your collection as they may have been exposed to an infectious agent. Ideally show birds and birds for sale should always be housed separately from breeding birds. o keep a register of all movements of your birds in and out of your premises
Information, education and contacts
Avicultural associations and bird clubs have an important role to play in educating new bird keepers about practices to maintain the health of aviary birds and also have a responsibility to continuously improve the knowledge of all their members with regards to health risks and best practices to maintain a healthy collection.
As part of their educational activities, through meetings and publications, avicultural clubs and societies should:
o Actively and regularly publicise this Biosecurity Code of Practice in their magazines, on websites and social media, and at meetings and events as a practical set of guidelines to help aviculturists maintain the health of their birds
o highlight the importance of health management and biosecurity measures as a component of minimum standards of aviary bird husbandry
o Provide specific information and presentations on cleaning and disinfection principles for prevention of avian diseases or parasites in their aviaries
o Provide members with contact details for local avian specialist veterinarians or other relevant authorities and hotlines in case of a bird-health emergency.
