In comparison, the non-specialized fruit-eating birds that they compete with for the mistletoe berry, such as the spiny-cheeked honeyeater (Acanthagenys rufogularis), have a more complex digestive system that takes longer for the fruit seeds to pass, and in the process the seeds are subjected to more mechanical and chemical action in the gut ...
Flamingoes are gregarious wading birds, usually 3 to 5 feet (0.9 to 1.5 m) tall, found in both the Western and Eastern Hemispheres. Flamingos filter-feed on shellfish and algae. Their oddly shaped beaks are adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down. American flamingo, Phoenicopterus ruber (O)

folivores: birds that forage for and eat leaves, such as hoatzin and mousebirds. [141] [146] frugivores: birds that forage for and eat fruit, such as turacos, tanagers and birds-of-paradise.

Unusual for birds of prey, the palm-nut vulture feeds mainly on the fleshy fruit-husks of the oil palm and on the palm-fruits of Raffia palms, as well as wild dates, oranges, other fruits, some grains and acacia seeds. [13] [14] These fruits make up over 60% of the adult bird's diet and over 90% of the juvenile bird's diet. [10]
They are mainly solitary birds, eating insects and fruit. Figs and numerous other species of fruiting tree and bush are visited. An individual barbet may feed on as many as 60 different species in its range. They will also visit plantations and take cultivated fruit and vegetables.
