Urban bird communities exhibit high population densities and low species diversity, yet mechanisms behind these patterns remain largely untested. We present results from experimental studies of behavioral mechanisms underlying these patterns and provide a test of foraging theory applied to urban bird communities. We measured foraging decisions at artificial food patches to assess how urban habitats differ from wildlands in predation risk, missed‐opportunity cost, competition, and metabolic cost… 
Linking Foraging Decisions to Residential Yard Bird Composition
Differences found in foraging behavior were indicative of differences in habitat quality, and thus this study lends additional support for native landscapes to help reverse the loss of urban bird diversity.
Differences in Patch Use Behavior Between an Urban and Rural Species: Effects of Distance from Shelter and Wing Molt-Gaps
This work predicted that the house sparrow, a widespread urban species, is less sensitive to variations in predation risk, while foraging, than its rural (less urban) congener, the Spanish sparrow.
Perilous choices: landscapes of fear for adult birds reduces nestling condition across an urban gradient
Predator fear effects influence reproductive outcomes in many species. In non-urban systems, passerines often respond to predator cues by reducing parental investment, resulting in smaller and
Foraging Behavior of Urban Birds: Are Human Commensals Less Sensitive to Predation Risk than their Nonurban Counterparts
The hypothesis that the cost of predation has less effect on the foraging behavior of urban than nonurban birds, although alternative explanations include differences between species in the degree of neophobia, or variations in their ability to assess predation risk, is supported.
Closely related gull species show contrasting foraging strategies in an urban environment
The variability in urban habitat utilization among closely related species is highlighted, stable isotope signatures of urban diets in wild birds are assessed, and ecological implications of the relative contribution of urban and marine foraging are discussed.
An experimental evaluation of foraging decisions in urban and natural forest populations of Anolis lizards
The observed patterns in foraging behavior are driven by differences in perceived predation risk, foraging motivation, or neophobia, and the importance of understanding how urbanization influences animal populations and their persistence in anthropogenically-modified environments is emphasized.
Is Density-Dependent Resource Harvest A Reliable Habitat Indicator for Conservation and Management?
This work measures the quitting-harvest rates of red-backed voles foraging in artificial resource patches located in three different habitats where population density was manipulated to show that rapid food renewal during the 2006 experiments increased the voles' foraging costs, and their qui...
Living in the city: resource availability, predation, and bird population dynamics in urban areas.
Antipredator strategies of house finches: are urban habitats safe spots from predators even when humans are around?
The results suggest that house finches may perceive highly urbanized habitats as more dangerous, despite the lower number of native predators, due to the presence of human activities, which could increase risk or modify the ability to detect predators.
Foraging in space and time structure an African small mammal community
The combination of trapping and foraging provided a mechanistic approach that integrates behavior into community ecology by ‘asking’ the animal to reveal its perspective of the environment by using spatial and temporal foraging decisions—as behavioral indicators—to guide the understanding for across-taxa species coexistence.


Predation on artificial bird nests along an urban gradient: predatory risk or relaxation in urban environments?
Urbanization - the anthropogenic conversion of natural ecosystems into human-dominated ecosystems - has occurred on global scales. The human-dominated landscape presents particular challenges to
Foraging Theory, Patch Use, and the Structure of a Negev Desert Granivore Community
Five mechanisms of coexistence in a community of three common rodent species inhabiting sand dunes in the Negev Desert, Israel found that G. allenbyi tended to be the most efficient forager and J. jaculus the least efficient foragers regardless of microhabitat, sand habitat, or month.

A technique for using patch giving up densities to investigate habitat preferences, predation risk, and interspecific competitive relationships is theoretically analyzed and empirically investigated in a community of four Arizonan granivorous rodents.
Competition between birds and mammals: A comparison of giving-up densities between crested larks and gerbils
A low giving-up density demonstrates the ability of a forager to Profitably harvest food at low abundances and to profitably utilize the foraging opportunities left behind by the less efficient forager.
Diurnal Octodon foraged more (had lower GUD) in the absence of predators (although this was confounded by a numerical increase resulting from predator exclusion), but the lack of a significant cover × predator exclusion interaction and thermoregulation studi...
Abstract We studied nest predation pressure on birds along an urban gradient in urban parks in three Finnish towns. Artificial ground nests with Japanese Quail (Coturnix coturnix japonicus) eggs were
Predation Risk and Competition Affect Habitat Selection and Activity of Namib Desert Gerbils
It is proposed that high susceptibility to predation results in a shared preference for the safest habitat and leads to competition for limited resources.
Settlement of breeding European Starlings in urban areas: Importance of lawns vs. anthropogenic wastes
We examined shifts in the feeding habits of European Starlings along an urban-rural gradient in northwestern France by comparing the diet of nestlings in three habitats: urban, suburban and rural
Factors Affecting Gerbil Foraging Behavior and Rates of Owl Predation
It is suggested that predation interacts with resource competition to determine the distribution and habitat separation of G. allenbyi and G. pyramidum and is distinguished among owl species, as indicated by changes in patch use and habitat selection.
Measuring Patch Assessment Abilities of Desert Granivores
Experiences with several desert rodent and avian species suggest that Merriam's kangaroo rat may obtain the best estimate of patch quality, followed by the round-tail ground squirrel and Arizona pocket mouse, and Gam- bel's Quail appeared to be the least sophisticated forager and exhibited only a fixed-time strategy.
