Mechanisms of socially facilitated feeding in Zebrafish (Danio rerio)
Learning & Behavior - The social facilitation of feeding, where individuals increase their feeding behavior in the presence of conspecifics, is widely documented, but the underlying mechanisms...

"Sunny wings"
I came across a mob of Cedar Waxwings who seemed to be eating flower petals from this apple tree. Anyone know if this is a known behavior?
