i have a two year old hybrid macaw, she is very sweet and well behaved. Recently when her and I cuddle she diggs in the blankets or other loose materials. I know for some birds such as African Greys this is a part of their natural behavior but I dont recall this being in a macaws repatoir, atleast not one past a few months old. Does this mean that she might be nesting? If so, is there any thing i should do ?
