At Monteverde, Costa Rica, 10 successional plant species used 14 hummingbird species for pollination. Displacement among flowering seasons suggests that the plants competed for polli- nators. There was no evidence that the flowering of one plant influenced hummingbirds to abandon another. Pollination in simultaneously flowering plants likely suffered nonetheless, since birds tended to move indiscriminately among flowers of different species and could lose much pollen between successive visits… 
POLLINATION ECOLOGY OF THE SPRING WILDFLOWER COMMUNITY OF A TEMPERATE DECIDUOUS FOREST
TLDR
Although inadequate pollination seems likely in the community, supplemental hand-pollination significantly improved fecundity in just 3 of the 12 species I examined, and it is the prevalence of such traits, rather than floral specialization or character displacement, that distinguishes the forest spring wildflower community from other communities with potentially inadequate pollinator service.
Convergence, Competition, and Mimicry in a Temperate Community of Hummingbird-Pollinated Flowers
TLDR
This temperate flower community, which resembles some associations of conver- gent Mullerian and Batesian mimics, appears to have evolved its characteristic convergent structure because the advantages of using similar signals and rewards to share the same hummingbird pollinators outweigh the disadvantages of diverging to reduce interspecific competition.
Competition for dispersers, and the timing of flowering and fruiting in a guild of tropical trees
TLDR
It is hypothesize that selection may be stronger for the divergence of flowering times than for fruiting times, especially within guilds of related species.
Evaluation of Character Displacement Among Plants in Two Tropical Pollination Guilds
TLDR
The absence of expected pattern indicates that competition never occurs or that competition is an inconsequential ecological event, but attribute absence of pattern to the following aspects of biological variability: the nature of interspecific interactions varies with changes in species composition, which occur over short distances, and Gleasonian ecologies that change distri- bution and abundance faster than natural selection or diffuse competition can screen out improper phenotypes.
The Hummingbird Plant Community of a Tropical Montane Rain Forest in Southern Ecuador
: The diversity of a hummingbird plant community in the eastern Andes of southern Ecuador was studied on the equivalent of a hectare (two 500 ′ 10 m transects) at 1920 - 2100 m a.s.l. over the course
Island Ecology: Reduced Hummingbird Diversity and the Pollination Biology of Plants, Trinidad and Tobago, West Indies
TLDR
Pollination service on Tobago is currently more erratic than on Trinidad, and has been sufficiently erratic in the past to select for increased nectar production but not so erratic as to override other, stabilizing, selective forces on flowering times.
Hummingbird pollination of Malvaviscus arboreus in Costa Rica
Abstract Malvaviscus arboreus is a self-compatible shrub or small tree native to Costa Rica. Floral morphology, nectar flow pattern, and observations of visitor behaviour, all indicate that flowers
Nectar in Hummingbird–pollinated Neotropical Plants II: Interactions with Flower Visitors
We documented the diurnal pattern of nectar volumes in flowers of seven Neotropical hummingbird–pollinated plant species that were open to flower visitors and compared these standing crop data to
Nectar in Hummingbird-pollinated Neotropical Plants II: Interactions with Flower Visitors1
TLDR
The diurnal pattern of nectar volumes in flowers of seven Neotropical hummingbird-pollinated plant species that were open to flower visitors and compared these standing crop data to nectarvolume in flowers protected from visitors is documented to argue that understanding the evolution of plant– pollinator interactions requires understanding the relationship between nectar production and standing crop.

Ecological and Behavioral Determinants of Pollen Dispersal in Hummingbird- Pollinated Heliconia
  • Y. Linhart
  • Environmental Science
    The American Naturalist
  • 1973
TLDR
The dispersed forest species of Heliconia were feed upon by nonterritorial birds, whereas the clumped forest-edge species were fed upon primarily by territorial birds, and this interaction may be advantageous to both organisms by lowering the competition for food among birds and the Competition for pollinators among the plants.
Competition for pollinators as a stimulus for the evolution of flowering time
TLDR
It was found that in the spring, insects competed for flowers but that after the cornucopian species had completed their flowering (throughout the summer), flowers competed for pollinating insects.
The Impact of Seasonal Flowering on the Biology of Some Tropical Hummingbirds
TLDR
The present study was undertaken to discover two things about the habits of several species of hummingbirds living in such a wet-dry seasonal climate, and to understand the importance of seasonal flowering activity in the evolution of techniques for biological exploitation of the dry lowlands of Middle America, and especially the influence on the territorial systems of the hummingbirds.
Competitive relationships of some bog ericads for major insect pollinators
TLDR
The inconstancy of pollinators rather than their low numbers is proposed as an additional explanation of why the peak flowering times of ericaceous shrubs do not overlap.
Competition for the Nectar of Centropogon valerii by the Hummingbird Colibri thalassinus and the Flower-Piercer Diglossa plumbea, and Its Evolutionary Implications
TLDR
In the highlands of southern Costa Rica, one of the commonest native plants of second-growth areas is Centropogon vu&i Standl, a perennial shrub with orange-red tubular flowers, which is pollinated primarily by the Green Violet-ear, an altitudinal migrant.
Insect-flower associations in the high Arctic with special reference to nectar'
TLDR
It is concluded that flowers and floral groups are important as aggregation centres for insect populations in this environment with competition between flowers for pollinators rather than among pollinators for nectar.
Foraging for Insects by a Tropical Hummingbird
TLDR
This paper discusses foraging for insects in one Costa Rican species, the Long-tailed Hermit Hummingbird, Phaethornis superciliosus (hereafter referred to as PhaETHornis), which ranges from southern M6xico to Bolivia and Brazil.
Foraging Patterns and Resource Utilization in Seven Species of Bats in a Seasonal Tropical Forest
TLDR
Competition for fruits was more important than competition for nectar and pollen in determining species diversity in this bat community, and a combination of the timing of plant—reproductive behavior and bat foraging characteristics promotes long—distance outcrossing and seed dispersal.
ASSORTATIVE POLLINATION IN LYTHRUM
TLDR
The purpose of this investigation was to obtain direct evidence about bee and lepidopteran flower-constancy by comparing the extent to which these pollinators deviated from random pollination in the same bispecific population under the same environmental conditions.

TLDR
The functional significance in the variety and in the assortment of flowers visited primarily by bumblebees in one habitat in Maine is determined and may serve as a model applicable to other plant assemblages and pollinators.
