Hi first of all can i just say that i am really grateful to all who post information and share their knowledge on these sites,

without some of you around i would have never been aware of a sign of illness which could have killed 2 of my birds! luckily i saw a forum post about signs of illness and got my birdies to an avian vet in time,

but i have a little problem,
i have had esso annd chivvy (esso is a a 7 month old normal grey i believe male and chivvy is a 6 month old pied i believe female) or so i have been told, both are amazing fun and i got them after they were an unwanted gift (we are now completely inseperable)

both have clean bills of health although esso is a bit overweight, im having difficulty trying to figure out there body language now,
recently chivvy has started singing (not very well but bless her she tries, she also sometimes screams) i think she learned from esso because she seems to be able to mimic some of the basic sounds he creates,but i dont know what this means, they make kissing noises to each other all the time and also whistle simple tunes,
esso displays some behaviour patterns of birds that would be courting, i.e he spreads his wings and creates the heart shape, they spend lots of the day grooming each other, but then sometimes fight (not majourly its just a little noise really) is this signs that they are going to or may already be courting?
please help as i love them to bits and want to know all i can about them
i hope i provided enough information here, i just know how many millions of different things can be going on in a birds head so provided as muc info as i could think of
