The grays are all exhibiting not quite abnormal but definitely unusual behaviors this time of the year, Wolf. My Sophie CAG, which is, like your Kookooloo, not a 'touchy-feely' bird has been begging for caresses in earnest again. She is broody and getting ready for, possibly, a second clutch because I finally threw away her eggs.
Isis Redbelly begs for head scratches all the time BIG TIME, she also likes to ride not only my shoulders but also my head. Zoey Senegal, on the other hand, is much more affectionate and trusting. She rests her beak on my face, leans against my neck and even lays down on my hand so I can kiss her feet and belly.
