If your poop is dark green it usally means that you have diarreia or your about to have diarreia.
that means it might be sick. If the parakeets usual poop is green that might not mean its sick. But if this is like, the first or second time that its had green poop go to a vet!
The green colour is due to "biliverdin", which is usually converted to "bilirubin" by biliverdin reductase which is then excreted in the bile juice and gives the brown colour of feces, so if this reaction doesnt take place, then biliverdin turns poop green!
This could mean that you have a cold.
Green poop can be dangerous in massive amounts. If you poop once a day for a week and you have green poop 3 out of the 7 days, that's fine. But if you take a poop and plug the toilet with green poop than that is too much. You might want to get yourself checked for the swine flu cause you probably have it
You can poop green poop if you eat a lot of green veggies. Or a lot of green stuff...

Green poop is normal, and is caused by something you ate. There is probably no reason to be concerned.
Your stool can be green if you ate green things, such as spinach.
