Hummingbird–sapsucker associations in northern climates

Evidence is presented to support the hypothesis that the dates of spring arrival and northern breeding distribution of the ruby throat, and probably the rufous hummingbird, are determined by a commensal relationship with the yellow-bellied sapsucker.

Frequency of arthropods in stomachs of tropical hummingbirds

The contents of stomachs and crops of collected birds represent an obvious source of dietary information and can provide an indication of the frequency and generality of arthropod-foraging in hummingbirds.

Diets of Land Birds from Northeastern Venezuela

Most birds were generalist feeders, including a wide variety of both invertebrate and plant taxa in their diet, and several species tended to be more frugivorous at the study sites than in previous reports.

Behavioral, Ecological and Morphological Correlates of Foraging for Arthropods by the Hummingbirds of a Tropical Wet Forest

Data on arthropod prey do not support the notion that hummingbirds visit flowers for insects rather than nectar, and there is no evidence to suggest that their bills are specialized for extracting insects from flowers, as well as no parameter of wing morphology shows a clear relationship to strategies of nectar exploitation.

Nest attentiveness in hummingbirds

Examination of nest attentiveness in nesting Broad-billed, Violet-crowned, and Black-chinned hummingbirds in southwestern New Mexico and south- eastern Arizona shows similar attentiveness patterns, particularly as regards incubation and to lesser degrees with other stages of the reproductive cycle.

Feeding territoriality in migrant rufous hummingbirds: defense of yellow-bellied sapsucker (Sphyrapicus varius) feeding sites

Comparisons of the time budgets of birds defending tree sap with those of territorial individuals in nearby habitats showed that these birds spent less time foraging and more time perching than birds in even high-quality subalpine meadows.

Breeding in the cold? A White-eared Hummingbird (Basilinna leucotis) winter nest record from the mountains of Southern Oaxaca, Mexico

ABSTRACT We report the finding of a White-eared Hummingbird (Basilinna leucotis) nest during the winter. The observation took place on 9 February 2019 in San José del Pacífico, Oaxaca, Mexico, in the

Energy regulation by traplining hummingbirds

A published model of constant diurnal energy accumulation by territorial hummingbirds does not accurately reflect the temporal distribution of feeding behaviour of traplining hummingbirds, and model birds with decreasing diurnal net intake rates met their energetic needs with fewer flowers than those with constant net intake, and spent less time foraging.

Energy limitation of hummingbird populations in tropical and temperate communities

The total daily energy demand by the hummingbirds and the daily energy supply available from floral nectar for each community census are calculated and it is suggested that the supply/demand economics of coevolved mutualisms favour the evolution of complete resource use.

Optimal niche space of the red-winged blackbird: spatial and temporal patterns of nesting activity and success and nesting success in marsh and upland habitat is studied.

Influence of Economics, Interspecific Competition, and Sexual Dimorphism on Territoriality of Migrant Rufous Hummingbirds

Comparisons of feeding territories of S. rufus and other nectarivorous birds indicate similarities which suggest that these systems may be subject to similar economic constraints.

Foraging for Insects by a Tropical Hummingbird

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.
