The bird pollination systems of the New and Old Worlds evolved independently, and differ in
many aspects. New World plants are often presented as those adapted to hovering birds …

Thousands of plant species worldwide are dependent on birds for pollination. While the
ecology and evolution of interactions between specialist nectarivorous birds and the plants …

The nectarivory of sunbirds in the Old World and hummingbirds in the New World evolved
independently. While both groups are specialised in their feeding apparatuses …

Plant–bird pollination interactions evolved independently on different continents. Specific
adaptations can lead to their restriction when potential partners from distant evolutionary …

The long‐standing paradigm that pollination systems adapted to hovering birds evolved only
in the New World was recently challenged by the discovery of hovering pollination by Old …

Why do hummingbirds hover while Old World nectar‐feeding birds perch? A unique
opportunity to explore this question is presented by the invasion into Africa of a plant …

Trait matching—a correlation between the morphology of plants and their pollinators—has
been frequently observed in pollination interactions. Different intensities of natural selection …

Plant–hummingbird interactions are considered a classic example of coevolution, a process
in which mutually dependent species influence each other's evolution. Plants depend on …

Bird pollination occurs in at least 10,000 plant species, representing more than 500 genera
and 68 families. Bird-pollinated plant species are found mainly in the tropics and temperate …

Recent studies indicate that short-billed birds which visit flowers opportunistically for nectar
are important pollinators of African plants and select for floral characteristics which are …
