....snip... With around 15 million Blue Tits over wintering in Britain, I
rather
suspect that stopping parakeets from eating at one bird feeder would not
count as an essential conservation measure.

We had similar problems with feral pigeons so we bought a squirrel-proof
bird feeder. The pigeons are too large to get at the seed. A parakeet
might get through but worth a try.

Interesting to hear about your problems though; we have ringnecks in Enfield
now (N. London, just inside the M25) but they stay in the tops of trees and
I've never seen one even close to a bird feeder. I wonder what's the
difference!
