Some of my houseplants not on those lists...
Orchids (Oncidium, dendrobium, cymbidium, phalaenopsis, and Cattleya)
I'll be googling it but if anyone here knows already I'd appreciate the time saved
African Violets are fairly resilient and pretty simple to water (just let them soak the water up from an underlying tray), given enough light they'll flower constantly. Likely my favourite plants after the orchids.
Christmas cactus are a bit less resilient, but also fairly easy with attractive flowers.
Rubber plants are hard to kill. Spider plants are considered hard to kill but I think they're one of the more delicate "hard-to-kill" plants. I don't know about the toxicity of pothos to BIRDS... I know it's listed as toxic to cats, but I also know it's a popular plant in aquariums where the fish are definitely nibbling on it all day.
If orchids are safe to birds, they're DECENT with infrequent watering... They store water in their bulbs which helps them tolerate a bit of neglect... They're a bit more involving to water when you do, though.
Jade's a fairly good low-demand plant... A good rule of thumb is the thicker the leaf, the more resilient it is...
Plants don't really need water that often though... Maybe once a week or so during the brighter growing season... Every other week in the winters...
Also I should add, pothos is a nice plant because it's fairly resilient to both over-watering AND underwatering...
A nice way to plant certain plants is to use a clay pot, plant the plant in the clay pot, then plant the clay pot in a larger self-watering pot using peat moss. The clay allows water from the peat moss to be absorbed into the soil inside the clay pot as the plant uses the water up. The self-watering reservoir at the bottom holds water which passes into the peat moss as it loses water to the soil inside the clay pot. When you water, water around the clay pot into the peat moss.
This prevents you from over-watering the plant, as the plant will suck up water as it's needed, and the larger pot full of peat moss (coconut husk would also work well) acts as a long-lasting supply. The medium holding the moisture will also increase humidity around the plant slightly.
