If your parakeet has sticky, but dried head feathers he could have an Trichomonas infection. This type of an infection is caused by a protozoal organism and produces heavy mucus which the bird will spit up. When it is flung around from its mouth, it will stick to the feathers and when it dries it feels just like someone had put hair styling gel in the feathers.
The treatment for this type infection is Ronex or Ronivet - S or any medication that contains Ronidazole.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
