Use of the tongue

Yellow -vented Bulbul

Brown-throated Sunbird, female of the species.

Pink-necked Green Pigeon, male.
The red juicy seeds of the Simpoh Air or Shrubby dillenia are attractive to many birds.  In the above pictures , I noticed that the tonque is vital as a balancing organ to hold the seed and position it between the beak and then flip the seed into the mouth of the bird.  This is important because only when it is held steady and central that the birds can easily gulped the seed.  Failing which the seed might fall and be wasted.
