Yes, I've made a post in the Issue Tracker here.
But this has been a problem for a while now. At first I thought it was because other dinos/vehicles were making them panic, but then I got the low health notification for one of my sinosauropteryxes, and when I cycled through them, saw this one. Completely ignoring the fact that starvation is setting in, in favor of roaming and socializing.
I love these little guys, but it's almost not worth ever having them in a park because of this.
