Why so sad?? (Manorina melanophrys)

Walking in the BotGdns this afternoon I heard the metallic 'ting' ... 'ting' sonar-like call of the Bellbird / Bell Miner. Difficult to see in the foliage until they move (i.e. fly away) because of their distracting call which seems to come from almost every direction. Finally located this little thing looking so sad. Maybe it lost its 'ting'. It will be fun to return in later months to witness the riot of sound when they are feeding their young although I'll need ear-plugs!
