The study in question concluded that wild starlings, when fed wax worms injected with levels of fluoxetine (the generic name for Prozac) equivalent to what the birds might be exposed to by “feeding on invertebrates at a wastewater treatment plant,” showed “conspicuous changes in foraging behavior.”

To clarify, this study wasn't looking at actual birds in the wild. Not saying we shouldn't be concerned about this, but not a fan of this study.
