When I peek under the cover s/he is actually sleeping on the seed dish!!
Just making sure is normal misbehaviour at night - is spending a lot of time with me at the mo cos I am working at home, although usually has 3 or 4 hours to him/herself during day and seems reasonably happy.
I think just maybe likes cuddles and company at night - but if sleeps with me will be extremely flat bird

Not used to having such a tame one - now 10.5 weeks old (but who's counting...)
Cheers
