The plant life is as amazon themed as possible in a situation like this. There will be a lot of nut trees and fruit trees, all plants that have fruits/nuts/vegies will be in one area. There will b ea lot of trees and very few flowers. The HUGE amount of trees will bring so much cover for the birds from the cats. Before cats can even get close to climbing the tree the bird will quickly fly into another. It has more of a rainforest feel as well. Some plant fruits/etc. Include grapes, macadaimia, orange, walnut, mango, etc. These trees will be the trees that the following bird will feed on and live inside.

There will also be a pond, it will be stuck to the back left side of the backyard. The pond will have no concrete or anything. It will just have a liner and soft, large and beautiful pebbles of colors from clay brown, marble white, dark black and gray covering the bottom. All walls will be on a 60 degrees angle, so that the walls don’t collapse. The pond will be rectangular and 10 meters width and 12 meters length. There will also be two levels, one that is 1.2 meters and at the deep end it will be 2.6 meters and one that is 40 centimeters and 60 centimeters on the deep end. The pond will have a gradual slope to the deep end. There will also be a cave on the deep end, which will be 1 meter deep and a 1.5 meter diameter. There will be 3 entrances and all large enough for a full grown man to easily fit into. This means the deepest point in the pond will be 3.6 meters deep. The shallow level will of course will be on the outsides, this will also help people that have fallen in climb out (I have a dog but no children under 14). There will a part that is extremely shallow, which is on the opposite corner to a waterfall, about 4 centimeters deep and square. It will be square and about 70 centimeters by 70 centimeters for the birds and ferrets to bath in rarely away from predator fish. 

In the liners will be lots of small holes cut to put plants in. The pebbles will also cover the plants so the fish don’t uproot it. There will be A LOT of plants (most Amazonian and as tough as possible) and more being in the deep end. All of these plants can help keep the water much warmer and cleaner. 

There will also be a water fall on the deep end of the pond, the middle of the water fall will be at the corner of the deep end, it will expand to the sides of the deep end, going towards the other two corners of the pond, but it won’t go all the way, as you can tell the water fall will be quite large, about 8-9 meters long and in a < shape. Water will come down all across the water fall, the water fall will also be a stream to incourage the water to come down all across the water fall, it will have to keep getting shorter as it gets further to incourage the water to go all over the water fall. The whole water fall will be going down hill on both sides. It will also be sticking out a bit so you can sit on the inside of the water that is falling and look outside at the whole pond. I will be about 2 meters tall at the tallest part. There will also be plants planted in the shallow stream. The waterfall will be built in the garden as the waterfall is on the deep end and the deep end is on the inside of the pond. 

On the outside of the pond there will be beautiful bricks (identical to the ones of the garden), 2 stacked on top of each other, this goes all the way around the pond. Between the first brick and the second brick there will be a gap (only in the ones that join the garden), this gap will let all the over flowing water come out from the sides and them go into the garden. The pond will be under the sun for about 5 hours. The average weather is around 16 in my area year round.

In the pond there will be 3 pumps all at different points supplying water to 3 filters which are inside of the waterfall. There will also be a strong skimmer as there are lots of overhead trees. There will be a heater making the pond a constant 24 degrees celcius.

There will also be a decking/pergola part which won’t be part of the square backyard. To exit into a front yard you will have to go through 2 doors, the exit that leads to the front yard is on the opposite aide of the house to the decking and pergola 

The animals:

4 Hyacinth Macaw (2 of each sex)
4 Blue and Gold Macaw (2 of each sex)
2 Toco Toucan (1 of each sex)
2 Keel-Billed Toucan (1 of each sex)

4 Silver Arowana (at least 1 of each sex)
2 Redtail Catfish (1 of each sex)
8 Koi (2 of each variety, 1 of each sex)
30 Freshwater Angelfish (at least 5 of each sex)
100 White Cloud Mountain Minnow (at least 20 of each sex)
200 Amazonia
n Glass Shrimp (at least 50 of each sex)

1 Labrador Retriever (male)
2 Savannah Cat (1 of each sex)
2 Maine Coone Cat (1 of each sex)
2 Ferret (1 of each sex)  

So my question really is can (all birds, all bird young/egg, Koi (1 meter), Silver Arowana (1.2 meter), Redtail Catfish (1.5 meter)) survive with these cats in a place like this?

I think they will all the fine together except for the Ferrets (don’t know about the ferrets) because cats are not amazing climbers and most of the trees will be around 4 and above meters so they can never catch the birds, also the birds are all extremely smart. Their  nests will be on the fence were re cats can’t climb, even if they can climb to it yet won’t be able to fit through the best hole, also each nest will have 2 entrances. They will be quite large as well. As for the fish, each grow over a meter, specially the Redtail Catfish, I don’t think the cat would try and catch a fish faster and larger than itself in the water. Also the pond is abs
olutly huge and very deep, the cats can never reach the fish. I won’t care if they eat the small fish. 2 things
I am unsure of are cats and ferret living together in an area like this an if the birds come down to the ground the cats might sneak up on them. 

That was my question, so what so you think? Thanks for reading and answering

Also are hedgehogs safe in a place like this.
The space is completly and safely sealed of from local wildlife. All animals can do fine with each other, the cats seem to be the problem.

Something like this will cost around AU $120,00.00 I don’t wan’t the cats wrecking it. Probably won’t buy cats unless it’s 100% safe for all other animals.
Dw about the lab I have had him for two years and kept him with many pets and he wouldn’t hurt a thing. I this is the case I won’t get any cats or ferrets, ohh welll.
Can some more people answer so I can be sure? Thanks
About to repost in birds on my frigging iPhone. Phones are re worst web browsing tool.

For finches place specially designed thistle feeders that hold the small thistle feeds that they love. Other speciality bird feeders include hummingbird feeders to hold nectar, woodpecker feeders and jay feeders. Tube feeders are designed to prevent seeds spilling on the ground and keep the seeds dry. You could also set up a window feeder to see the birds from the comfort of your room.

Always check the food regularly to make sure it is dry and free from mold and clean up around the feeder to deter wasps, ants and other predators. If squirrels are a problem in your garden be sure to purchase a squirrel proof bird feeder.

Provide Fresh Water for the Birds

Wild birds need a source of fresh water for both drinking and bathing. You could provide this with water pans or bird baths. Place water containers at various levels as some birds prefer ground level, others will be attracted to water placed at a higher level. Place any water sources away from bird feeders as birds prefer a quiet place for bathing and preening. Attract the birds to your water source with a water dripper placed in the bird bath or a mister in the trees. The gentle sounds of running water will attract the birds and many birds enjoy a bath below the dripper or in a mister as it simulates raindrops on their feathers.

During the winter months a heated bird bath or one fitted with a de-icer will ensure the water is always at the right temperature and available for the birds.

Provide a Natural Environment

Let a part of your garden grow wild and scatter wild flower seeds through the area to provide a natural environment for the birds. hang bird feeders from trees or posts in this area. This will enhance the sense of security for the birds.

Your bird house must be a safe place for birds to nest and bring up their young. Here are some tips for making your bird house proof from squirrels, yellow jackets, snakes, cats, wasps, ants and other invasive birds.

Perches

There is no need to have any perches in your bird house. The nesting birds do not need them and they only provide a means for predators to gain entrance. many bird houses come with a perch under the entrance hole. Remove it!

Baffles

A bird house mounted on a pole can have baffles fitted to prevent predators from climbing the pole and gaining entrance to the bird house. A metal baffle is preferable as it cannot be chewed. A bird house mounted on a tree can also have baffles attached to the tree trunk.

Metal plates

A metal plate fitted with a small entrance hole can be placed over the original hole on the bird house. This will prevent predators from enlarging the hole to gain entrance.

Entrance Hole

use a bird house with a small entrance hole that is just large enough for the species of bird you wish to attract. A larger hole will allow invading birds to gain entrance and eject the baby birds inside.

Ants Nests

Regularly check around the bird house (and bird feeders if you have them) for ants nests. Deal with them quickly using a method that is not harmful to wild birds.

Metal Poles

For bird houses mounted on metal poles slip a large PVC pipe over the pole before mounting the bird house. This will deter squirrels, snakes and raccoons from climbing up to the bird house. You could also smear vegetable oil on the pipe.

Cats

Fit your cat with a collar with a bell to prevent her sneaking up on the birds.
