This bird started following my JRT and wanted to be noticed, at points it even started making weird noises to be noticed by my dog!! I never witnessed such a behavior in birds...?? Did you? Any more info about this bird's weird behaviour?

I know some parasite life cycle is taking over their host, and then the infected host exposes itself to predators to be eaten in order to continue the infection! It knows Snail and mice&rats can be a parasite's host. But there is no external evidence of the worm's existence within the bird host
