Hi, and thanks for asking questions first. Honestly, and I'm going to be completely up front with you, you should not have any pet bird except maybe a finch or canary that does not need human interaction. There is no parrot that you can keep as a pet and only give 2 hours a day to, least of all an Eclectus. And you also cannot put the bird and it's cage back in a room away from your main living room, they are all like having a young toddler or human baby, they need to be in the same room as you if you or anyone else is home, even if you're not directly interacting with them, otherwise they will hear you and start screaming constantly because they can not see you and they want to be in the same room as you. 3-4 hours a day, every day, of out of cage interaction with you is the absolute bare minimum for even a budgie or cockatiel. An Eclectus, any Cockatoo (the most difficult bird to keep, like a 4-5 year old human child) African Grey, Macaw, Amazon, these parrots require you to not only commit most of your time to them (2 hours only to a Cockatoo or Eclectus while the rest of it's day off in another room would be an absolute disaster) but you also have to rearrange your life and home for them. They must have their very large cages in the room you are in the most, and you must have stands/perches for them in pretty much every room of your home or be able to move one to each room, because if you are home then they must be in the same room as you or they will not only constantly scream but they will start to self harm and pluck if you aren't with them enough. Honestly, the fact that you said you want a Cockatoo or an Eclectus and then said you could only give the bird 2 hours a day and would keep the bird in a room with your turtles, this itold me that you need to hold off and do a lot of research about having pet birds. I have a Senegal parrot, a Quaker parrot, a Green Cheek Conure, and a cockatiel, plus several budgies (which live longer than 10 years, average with good healthcare is 15 and I had one that lived to be 18). All of my bird's main cages are in my living room, and then they all have sleeping cages in my bedroom. They have playstands in every room of my house. The ONLY time that my birds are ever locked inside their cages is when I'm not home. As soon as I get home from work they are all let out of their cages and are out the rest of the day. If I'm in my living room watching TV or reading they are there. If I'm in my office on the computer they are there. If I'm playing my guitar in my basement music room they are there. They sleep in my bedroom in smaller sleeping cages, we get up together, I cook them breakfast, prepare them their food for the day including pellets, supplemental seed mix, fresh veggies and fruits, oatmeal, eggs, grits, etc. I come home from work at noon and let them out for an hour until I have to go back. When I get home at 5:00 I let them out of their cages and they are out the rest of the night until we go to bed, and they are constantly with me. And I skip a lot of social events because I can't leave them alone in their cages all night. But it's my choice to do so because they are my family. And my birds are happy and healthy, and you'll find that my schedule and lifestyle is the norm for most of the members on here. And if I were to take on a Cockatoo, African Grey, Macaw, or other larger, more needy bird (needy meaning needing to be with you, on you, be held by you and petted by you constantly, cannot ever be left in a room separate from you) I would have to commit even more time. 2 hours a day doesn't even cover the time I spend every day making their food, cleaning their cages and stands, toys and bowls, clipping nails, giving them showers after I finish my own shower, and putting them to bed. That's more than 2 hours a day without even playing, scratching, holding, or talking to them. You get what I'm saying. The avian vet thing is always a problem, it's a problem here in the U.S. in a lot of places too. That is a must, as birds and their delicate, specialized healthcare is another topic you need to do a lot of research on before even thinking about getting any bird.
What our member was pointing out to you about housing a bird in the same room as your turtles is that it's a huge no no that you could not do. Turtles and reptiles in general carry a slew of bacterial and fungal diseases that do not make them sick, and may not make humans sick, but will surely make a bird sick or worse. I also have a Bearded Dragon that I love dearly, she is housed in a very large vivarium in my tv room in my lower level only because I don't want her vivarium anywhere near my birds or their cages. Humans can contract certain illnesses from reptiles, such as salmonella (most commonly known bacterial disease carried by turtles and other aquatic reptiles), but for the most part we're OK, where as birds can contract a host of bacterial and fungal infections as well as some nasty viruses from reptiles, specifically from an aquatic reptile. The bacteria and fungi that naturally live in and on your turtle's tank can kill a bird. And this isn't even discussing the potential dangers of just having a parrot and turtles together, birds are not to ever be left alone, unsupervised with any other pets, not dogs, cats, lizards, turtles, rabbits, not anything. They are prey animals and will automatically try to defend themselves against most any other animals, and if the animal is larger than the bird they can easily be killed. It happens all the time because you can't even leave two birds together unsupervised yet people think that you can. Your turtles would likely be injured by a large parrot, unless you have large snapping turtles. Any type of water sliders, map turtles, etc. cannot be left alone with a parrot.
I think you just need to do a lot of research about parrots as pets because I don't think you are familiar at all with what is involved in owning even a single, small parrot like a budgie, cockatiel, or small conure, let alone a large parrot like a Cockatoo, macaw, African Grey, Eclectus, Amazon, Pionus, Poicephalus species, etc. If you get to the point in life where you live in a house where noise and space will not be an issue, and where you are able to devote 5+ hours a day of direct interaction with them, plus be home most of the time to just be with them indirectly, then you may be able to keep a bird happy. Pets like turtles, bearded dragons, iguanas, monitors, cats, small animals like rabbits, ferrets, rats (very good pets, very intelligent and loving), etc. are the types of pets that are good for your situation, they are capable of being independent and don't constantly need you to be with them. I don't know about squirrels, lol, they aren't often kept as pets over here, but ferrets make great pets, so it's possible, lol.
