Not...getting...any...food

My train home was diverted via Timbuktu, so I walked home from Balham station. It was a lovely evening, and I enjoyed the stroll through Tooting Bec Common. I discovered a duck pond that I didn't know existed, then heard a terrific squawking and noticed this poor parent wood pigeon being bossed around by two large teenage offspring. She gave in eventually, but the expression in this photo made me laugh. The picture is begging for an appropriate caption!
