SummaryIn the course of other studies we have amassed a decade of records from banding, and observing the nests of, a breeding population of broad-tailed hummingbirds in Colorado, USA. In addition we have less extensive banding records for two other hummingbird species that migrate through the area but do not breed there. The rate of return of broad-tails between consecutive breeding seasons has been as high as 70% for females and 27% for males, suggesting substantial site fidelity and… Expand

Asynchronous changes in phenology of migrating Broad-tailed Hummingbirds and their early-season nectar resources.
TLDR
Dates of first arrival of Broad-tailed Hummingbirds to dates of flowering of plants they visit for nectar support the prediction that migratory species may experience the greatest phenological mismatches at the poleward limits of their migration and posits that the Poleward limit for some species may contract toward lower latitudes under continued warming.

NESTING SUCCESS AND PRODUCTIVITY OF HUMMINGBIRDS IN SOUTHWESTERN NEW MEXICO AND SOUTHEASTERN ARIZONA
-Predation was the major source of nest failure for hummingbirds studied in southwestern New Mexico and southeastern Arizona, accounting for nearly 80% of all failed nest attempts. Predation on eggsExpand
Resource value affects territorial defense by Broad-tailed and Rufous hummingbirds
TLDR
It was found that chasing was the default response to the presence of an intruder, and chip calls and hovering were added to intensify a chase. Expand
SEX RATIOS AND BILL GROWTH IN NESTLING
Implicit in the analysis of sex ratios in wild bird populations is the assumption that equal numbers of males and females are conceived, hatched, and fledged. Sex ratios biased in favor of femalesExpand
Balance between site fidelity and habitat preferences in colony site selection by herons and egrets
TLDR
High levels of colony site fidelity are found for each year of study, with its relative importance as a predictor for explaining colony distribution increasing drastically in the most recent five years. Expand
Variation in mutualisms : the spatio-temporal mosaic of a pollinator assemblage
Variation in time (annual and seasonal) and space (betweenand within-population) is examined for the pollinator assemblage of Lavandula latifolia (Labiatae), an insect-pollinated, summerflowering,Expand
QUALITY OF FOOD SOURCE AFFECTS FEMALE VISITATION AND DISPLAY RATES OF MALE BROAD-TAILED HUMMINGBIRDS
TLDR
The fact that male display rates matched female visitation rates provides further evidence that dive displays play a role in courtship and more work needs to be done to determine if the relationship between resource quality, female visitation, andmale display rates shows a threshold contingent on food availability. Expand
Automated Serial Sampling in Hummingbirds Obviates Laborious Ecological Studies of Behaviourally Induced Rises in Departure Stores
TLDR
Premigratory hummingbirds increased the duration of visits and thus total time spent at the feeders during the mid-day only and exhibited greater use of overnight torpor, as evidenced by a reduced rate of overnight mass loss. Expand
GREATER FOOD AVAILABILITY REDUCES TARSUS ASYMMETRY IN NESTLING BLUE TITS
TLDR
Food supplementation resulted in reduced asymmetry of nestling tarsus length, indicating that body asymmetry in early phases of life, not only in adult birds, depends on energy or protein intake. Expand
Automated tracking of wild hummingbird mass and energetics over multiple time scales using radio frequency identification (RFID) technology
TLDR
This work examines the feasibility of automating the collection of hummingbird mass data facilitated by low-cost, low-power radio frequency identification (RFID) technology and finds that careful arrangement of feeders and detectors allows for reliable detection even when detection range is low.

Pollen dispersal and optimal outcrossing in Delphinium nelsoni
TLDR
It is suggested that outbreeding depression will often occur on a much finer scale than previously recognised, especially in plants subject to restricted pollen and seed dispersal, and a short outcrossing distance is optimal for Delphinium nelsoni Greene. Expand
POLLINATOR CHOICE AND STABILIZING SELECTION FOR FLOWER COLOR IN DELPHINIUM NELSONII

TLDR
Evidence is presented that paleor white-flowered albinos are rare in populations near the RMBL; that selection against albino individuals occurs in the form of reduced seed sets relative to normal blueflowered individuals; that intrinsic fecundity of albenos is not lower than that of normal individuals; and that both hummingbirds and bumblebees discriminate against albino in a way sufficient to explain their low seed sets and consequent rarity.

Optimal foraging in hummingbirds: Rule of movement between inflorescences
TLDR
The movements of hummingbirds between inflorescences of scarlet gilia exhibited the following patterns: Although the hummingbirds appeared to avoid moving to the previous inflorescence, no significant correlation was found between the directions of successive inter-inflorescence movements. Expand
Survival and Dispersal of Male Long-Billed Marsh Wrens
TLDR
During the summer of 1968, all lakes on the refuge and most of the large lakes off the refuge within a 10-mile radius of the refuge center were carefully and completely censused in an effort to locate as many as possible of the banded birds that had returned. Expand
Competition for Hummingbird Pollination and Sequential Flowering in Two Colorado Wildflowers
TLDR
Fecundity reductions in natural and synthetic mixtures of D. nelsoni and I. aggregata indicate that the 2 species compete for hummingbird pollination and suggest that the competitive interaction involves interspecific pollen transfer. Expand
Body Size, Physiological Time, and Longevity of Homeothermic Animals
TLDR
Life span, like the other scales of physiological time, may be regarded, not as a direct product of natural selection, but rather as an allometric consequence of other characteristics subjected to natural selection. Expand
Factors in the Energy Budget of Mountain Hummingbirds
The abundant flowers of a compressed summer in the mountains provide an energy resource for exploitation by hummingbirds. However, the cold nights constitute a liability in their total energy budget.Expand
