Oriole pollination ofErythrina breviflora (Leguminosae): Evidence for a polytypic view of ornithophily

Plant Systematics and Evolution, 1977
Erythrina breviflora is visited by large numbers of passerine birds of which orioles (Icterus: Icteridae) are the primary pollinators. The flowers produce large quantities of nectar but they are rarely visited by hummingbirds. Inflorescence and floral morphology, and low levels of sucrose in the nectar probably explain the rarity of foraging ...

Chiropterophily and ornithophily inFreycinetia (Pandanaceae) in Samoa

Plant Systematics and Evolution, 1984
In Samoa, field observations, experiments, and SEM micrographs of hair and feather samples indicate the dioecious lianaFreycinetia reineckei to be both chiropterophilous and ornithophilous with the principal pollinators being an endemic flying fox,Pteropus samoensis, and an endemic starling,Aplonis atrifuscus.

ORNITHOPHILY AMONG THE HAWAIIAN LOBELIOIDEAE (CAMPANULACEAE): EVIDENCE FROM FLORAL NECTAR SUGAR COMPOSITIONS

American Journal of Botany, 1986
Data on the sugar compositions of floral nectars were used to test the hypothesis that the Hawaiian Lobelioideae (Campanulaceae) were pollinated by nectarivorous passerine birds (Fringillidae subfam. Drepanidinae, Meliphagidae) prior to widespread extinctions among the native avifauna.

Explosive flower opening in ornithophily: a study of pollination mechanisms in some Central African Loranthaceae

Botanical Journal of the Linnean Society, 1985
In many ornithophilous Loranthaceae pollination is accompanied by an explosive opening of the flowers, and diverse mechanisms have evolved in different genera to bring this about. These are described for the African genera Erianthemum, Englerina, Tapinanthus, Globimetula, Vanwykia and Plicosepalus.

Ornithophilie auf den Canarischen Inseln

Plant Systematics and Evolution, 1984
(1) On the Canary Islands and Madeira typical bird-flowers occur in at least twelve species of six genera, although true flower-birds are absent. This inconsistency is in part elucidated by field observations on exotic and wild plants of Tenerife. —(2) In the Botanical Garden of Orotava it could be observed that various ornithophilous plants, which ...
