Abstract: | Histological observations were made on the oesophagus of 2 birds showing different feeding habits. The birds taken for study included frugivorous form, M. haemacephala and H. smyrnensis, which is primarily piscivorous. Various histological modifications such as relative development of mucosal folds, mucous-secreting glands and musculature have been shown to be correlated with the specific feeding habits of the birds. |
