Many tropical plants are pollinated by birds and several bird phylogenetical lineages have specialised to a nectar diet. The long‐assumed, intimate ecological and evolutionary relationship between ornithophilous plants and phenotypically specialised nectarivorous birds has nevertheless been questioned in recent decades, where such plant–pollinator ...

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 ...

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.

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.

The ornithophily of Impatiens sakeriana does not guarantee a preference by sunbirds
Biological Journal of the Linnean Society, 2022Abstract In recent decades, the tight mutual specialization between nectarivorous birds and ornithophilous plants has been questioned, and instead, high degrees of generalization and interaction asymmetry have been highlighted. Here, we studied interactions among two sunbirds and four plant species in two Mount Cameroon forests, with two

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 ...

Evolution of Funnel-Revolver Flowers and Ornithophily in Nasa (Loasaceae)
Plant Biology, 2006Floral morphology, distribution, and flower visitors for 60 taxa of Nasa are investigated and compared to molecular trees inferred both from a combined marker analysis (ITS1 and trnL (UAA)) and from a single marker (ITS1). Flowers conform to two different floral types: Firstly, "tilt-revolver flowers", with spreading to reflexed, white to yellow petals

Botanica Acta, 1996
Abstract:In southernmost South America, the pollination biology of Calceolaria uniflora Lam. (Scrophulariaceae) was studied in the field. One of the most striking features of the flower of this species is a corolla appendage folded against the outside of the lower lip.
