Safe Aviary Plants and Toxic Plants for Birds@|what plants can i put in an outdoor aviary@|@|24

Plants not only add aesthetic value to an otherwise sterile-looking enclosure, but they also provide a more natural, engaging, and secure environment for the inhabitants to enjoy. Using plants to create visual barriers within the flight may help reduce aggression among cagemates by providing objects for the birds to hide behind.5 This in turn helps to make the birds feel more secure, and may therefore result in reduced stress levels. Foliage in the cage gives the birds something to occupy themselves with–birds often chew on, play within, and even build nests out of plants placed in their living space.

For this reason, care must be taken when selecting plants to decorate a flight. Both live and fake plants may be used, but all parts of the plant must be safe and nontoxic. The best fake plants to use are constructed of untreated silk and plastic. Make sure the silk plants do not have any components that may be easy for a bird to consume, tangle itself in, get caught on, or stuck by. Treated wood baskets and paper plants may be hazardous choices and are not recommended for decorating flights. Two benefits of using silk plants are: 1) they are not as easily destroyed by the birds, and 2) they can be scrubbed clean and disinfected as needed.

Live plants tend to demand more upkeep and may need to be replaced more frequently, as finches often love to pick them apart. Try to obtain plants that have not been sprayed with any pesticides or chemicals, and be sure to rinse the plants off before placing them in and around the flight. Do not add any fertilizers to the soil (they are toxic);6 if fertilizers are already present in the soil, repot the plant with uncontaminated soil. Leaving each plant in its pot is suggested, in case a plant dies and needs to be removed.

Helpful Hints41

Placement Plantings should be spaced appropriately to allow room for flight paths and to permit the birds to access to the floor of the enclosure. Walk-in enclosures should also have planned pathways for birdkeeper access. Be careful to provide climbing vines with trellis to support the weight of their growth; otherwise they could break the aviary mesh and allow escape of the birds.

Selection Aside from ensuring that the plant(s) you have selected are non-toxic, try to avoid purchasing plants which are tall and rapidly-growing as these will require constant pruning. In addition to considering what plants are best suited for your area, don’t forget to also consider the needs of the birds. Avadavats and Munias enjoy climbing small bamboos and grasses, for example, Munias and Mannikins prefer to weave their nests into grass clumps, and Weavers need palm leaves and broad-leafed grasses for nesting material.

Timing of Live Plantings Plants should be added to the enclosure as it is being completed. The plants should be allowed to grow sufficiently before adding the birds; this way, the plants will be better able to withstand being nibbled on. Ideally plants should produce their densest foliage while the birds are nesting.

Safe Aviary Plants25,17

When choosing plants for your aviary, consult a botanist or experienced gardener who can help you select plants which are suitable for planting in your locale (considering your hardiness zone, soil type, sun exposure, etc.). Below are some options which have been listed as safe for birds.

Toxic Plants

Plant toxicosis in birds occurs if they chew on or ingest toxic plants. The toxic reaction can be due to pesticide residues on the plants, or to toxins within the plants themselves. Birds which chew on toxic plants may develop oral irritation; if they ingest enough, systemic clinical signs can occur such as vomiting or diarrhea. There is likely significant species differences in sensitivity,16 and studies are lacking. However, plants which have been reported as toxic in some birds, or which are considered to be potentially toxic include:6,25,52,29,56,16,17,28

Avian Plant Toxicology Research

Studies of plant toxicity in finch species are greatly lacking, however a few studies were done using canaries. Unfortunately, because great variation exists among species, it is not safe to assume that plants which are non-toxic to canaries are equally safe to other birds and vice versa.

[external_link offset=2]

AUTHOR(S): Arai, M.; Stauber, E.; Shropshire, C. M. TITLE: Evaluation of selected plants for their toxic effects on canaries. YEAR: 1992 CITATION: J Am Vet Med Assoc, 200(9), +61404532026

ABSTRACT: Leaves or fruit from 14 plants considered to be toxic to pet birds were administered by gavage to 15 pairs of canaries (Serinus canaria). Each bird was given 0.12 to 0.70 g of plant material. One pair served as a control and was given distilled water. The plant materials were flash-frozen in liquid nitrogen, pulverized, and resuspended in deionized water for administration. Of the plants tested, 5 (

oleander, lupine, foxglove, yew leaves, and dieffenbachia) were considered highly toxic and were associated with acute death of birds. The remaining plant samples (clematis, Hoya carnosa, privet Ligustrum vulgare, parsley Petrosilium sativum, cherry Prunus sp., Pyracantha coccinia, rhododendron, black locust Robinia pseudoacacia, and wisteria) caused no, or only transient, clinical illness.

AUTHOR(S): Hargis, A. M.; Stauber, E.; Casteel, S.; Eitner, D. TITLE: Avocado (Persea americana) intoxication in caged birds. YEAR: 1989 CITATION: J Am Vet Med Assoc, 194(1), 64-66

ABSTRACT: Following two incidents in which a pet canary and three pet cockatiels died under conditions suggesting ingestion of avocado as cause of death, an experimental study was undertaken. Avocados of two cultivars were mashed and administered via feeding cannula to 8 canaries and 8 budgerigars. Two control budgerigars were given water via feeding cannula. Six budgerigars and 1 canary died within 24 to 47 hours after the first administration of avocado.

Deaths were associated with administration of both avocado cultivars. Higher dose was associated with greater mortality. The 2 budgerigars given water were normal throughout the observation period. It is concluded that avocados are highly toxic to budgerigars and less toxic to canaries. PM findings observed in some birds included subcutaneous oedema in the pectoral area and hydropericardium.

The following study was done using just budgies:

AUTHOR(S): Shropshire, C. M.; Stauber, E.; Arai, A. TITLE: Evaluation of selected plants for acute toxicosis in budgerigars. YEAR: 1992 CITATION: J Am Vet Med Assoc, 200(7), 936-939

ABSTRACT: Pairs of budgerigars were given samples, by gavage, of plants considered potentially toxic to pet birds. Samples were prepared by flash-freezing and powdering fresh plant material in liquid nitrogen and resuspending the material in deionized water for administration. Of the 19 plants tested, only 6 induced clinical signs of illness; these plants included

yew, oleander, clematis, avocado, black locust, and Virginia creeper (Taxus media, Nerium oleander, Clematis sp, Persea americana, Robinia pseudoacacia, Parthenocissus quinquefolio).

The other plants tested in this study were: bleeding heart (Lamprocapnos spectabilis), privet (Ligustrum sp.), honeysuckle (Lonicera sp.), lupine (Lupinus sp.), cherry (Prunus sp.), pyracantha (Pyracantha coccinea), boxwood (Buxus sp.), dumbcane (Dieffenbachia seguine), foxglove (Digitalis sp.), spindle bush (Euonymus alatus), poinsettia (Euphorbia pulcherima), rhododendron (Rhododendron sp.), and blue elderberry (Sambucus cerulea).

Note how some plants which appear well tolerated by budgies (lupine, dieffenbachia, foxglove) prove fatal to canaries, while some plants which canaries appear to tolerate (clematis, black locust) make budgies quite ill. Until more research is done, it is important to err on the side of caution and avoid any plant which may potentially be toxic. [external_footer]

Pol-e-cultures III: Coppice

Here is the latest (April / May) of my bi-monthly contributions to the PAWA e-news, the electronic newsletter of the Permaculture Association of Western Australia:

Last month, I caught the train from Oxford to West Sussex, rode my bike over rather more undulating country than I was anticipating and eventually made my way to Prickly Nut Wood amongst the historic Snape Copse. I had come to the home of Ben Law, woodsman and permaculture practicioner, to learn about coppicing. Coppicing is the practice of regularly cutting a tree right back to its stump, then allowing it to regrow. A copse is a woodland which has been regularly coppiced - some copses are hundreds of years old. Coppicing has a regenerative effect on trees such that they live much longer than can be otherwise expected.

So, why coppice? I learned from Ben that there are many answers to this question and Ben was practicing most of them at Prickly Nut Wood. Ben began with 8 acres about 20 years ago. In order to get this area into shape, a lot of the standing wood went into charcoal production (for use as biochar, artists charcoal and fuel). 20 years on, Ben has 100 acres of mostly chestnut trees (hence "Prickly Nut") with some beech, hazel, larch and oak with the possibility of some black locust to come.

When chestnut coppice is cut after say 4 years it is said to be on a 4 year rotation. Short rotations like this produce wood for things like walking sticks (until recently a major use of West Sussex coppiced chestnut). A five year rotation might produce bean poles or picket fence posts where a 30 year rotation might be used for post and rail fencing. Rotations of upwards of 30 years become useful construction timbers. And that's just chestnut. Each tree has its different suitabilities. For example, hickory is used for tool handles requiring rigid strength and ash for handles requiring flexible strength; willow is used to make cricket bats and black locust is said to last "a year longer than stone" in the ground or in the weather.

Having begun with charcoal as a kind of pioneer strategy while bringing derelict coppice into production, Ben still produces charcoal with wood of insufficient quality for other uses. This way nothing is wasted. Coppice products besides poles, timber and charcoal include logs for mushroom growing and firewood. An Australian study has shown that coppice that is used for firewood locally has a net sequestration of carbon per unit of energy produced in burning (around 0.06kg CO2 / kWh) - that is, it actually reduces carbon emissions. Given efficient stoves and local use, burning firewood from coppice is a more efficient heating fuel than gas or electricity.

There are also yields from bees, animals in the woodland, fungi and increased biodiversity. Ben is actually managing his woodland in an area which must be managed to preserve the mosses and lichens growing on the coppice stands. Coppice management is very amenable to such conservation, especially if it includes about a 10% canopy cover provided by uncut trees - this is called "coppice with standards." Coppice with standards increases wildlife habitat and the overall stability of a system.

I felt very lucky to learn from such an experienced woodsman with an understanding of permaculture and I gained a greater appreciation of the place of coppice in a permaculture. Not everyone can be a woods-person, crafts-person and and marketer like Ben and make a living from stewarding a woodland but coppicing can also be used as a management strategy in suburban forest gardens or in animal fodder systems, amongst other things. Coppice offers one of the best ways of capturing the sun's energy to meet many of our needs for fuel, fibre, fodder (and fungi!).
