Abstract Geophagy is widespread and well documented for mammals, but avian geophagy has only recently become the subject of serious scientific investigation. I analyzed data from 606 mornings of observations at a large avian geophagy site or “clay lick” in the southwestern Amazon Basin to examine the effects of weather on bird lick use. Birds used the clay lick on 94% of the mornings without precipitation or fog. Parrots dominated the site in both numbers of species (17) and individuals (>99… Expand
Food availability and breeding season as predictors of geophagy in Amazonian parrots
TLDR
It is found that the peak of geophagy occurred during species’ breeding seasons, which strongly supports the supplemental nutrients hypothesis, and joins a growing body of biochemical, physiological, behavioural, ecological and biogeographical evidence suggesting that a need for sodium is driving soil consumption in this classic model system of avian gephagy.

Observations of parrots at a geophagy site in Bolivia
TLDR
The occurrence of geophagy is recorded at a site in lowland forest in Bolivia with six species of parrot with a maximum of 1,044 birds on any one day. Expand
Use of Clay Licks by Maroon-Fronted Parrots (Rhynchopsitta terrisi) in Northern Mexico
TLDR
The first published report of clay-lick use by the Maroon-fronted Parrot (Rhynchopsitta terrisi) is presented, a species inhabiting high elevation temperate pine-oak forest of the Sierra Madre Oriental. Expand
The effects of tourist and boat traffic on parrot geophagy in lowland Peru

Diet and Geophagy Across a Western Amazonian Parrot Assemblage
TLDR
It is found that flower availability was highest in the dry season and fruit production peaked in the wet season, but that phenology patterns of the 20 most commonly foraged plant species suggest no serious food bottlenecks. Expand
Parrot Behavior at a Peruvian Clay Lick
TLDR
It is suggested that clay lick use strategies are molded by predation risk and competition acting on a suite of species with varying body size, coloration, and gregariousness. Expand
Avian Geophagy and Soil Characteristics in Southeastern Peru
ABSTRACT We observed ten species of psittacids, three species of columbids, and two species of cracids consuming soil from banks of the lower Tambopata River in southeastern Peru. Our study usedExpand
Effects of Diet, Migration, and Breeding on Clay Lick Use by Parrots in Southeastern Peru.
Introduction Soil consumption (aka geophaghy) is very common among mammals worldwide. A wide variety of mammals eat soil including wild and domestic ungulates, rodents and primates (includingExpand
Mineral Licks as Diversity Hotspots in Lowland Forest of Eastern Ecuador
Mineral licks are sites where a diverse array of mammals and birds consume soil (geophagy) or drink water, likely for mineral supplementation. The diversity of species that visit such sites makesExpand
Parrot claylick distribution in South America: do patterns of where help answer the question why ?
Geophagy is well known among some Neotropical parrots. The clay apparently adsorbs dietary toxins and/or provides supplemental nutrients. We used location data and 23 environmental layers to developExpand

Soil-eating by red leaf monkeys (Presbytis rubicunda) in Sabah, Northern Borneo
TLDR
Observations on the diet of a group of red leaf monkeys from Sabah, northern Borneo are summarised and the composition of termite mounds is compared with that of surrounding top-soil in an effort to determine possible reasons why termite-mound soils are selected. Expand
The effect of weather conditions on the behavior of ospreys in northwestern Washington
TLDR
In northwestern Washington, weather conditions have little or no effect on the behavior of breeding ospreys, and neither the rate of food delivery nor osprey brood size appears to be limited by weather-mediated foraging success. Expand
Variability in roost size in an Amazona parrot: implications for roost monitoring
TLDR
It is suggested that as long as misty mornings are avoided, morning roost counts were more effective as birds left more quickly and predictably, and the reliability of four roost counting regimes was tested. Expand
The effects of weather and lunar cycle on nocturnal migration of landbirds at Southeast Farallon Island, California
Proximal climatic and lunar effects on amval and departure of nocturnal migrant landbirds at Southeast Farallon Island (SEFI), California, were examined using multivariate and univariate statistics.Expand
Parrot behavior at a Rio Manu (Peru) clay lick: temporal patterns, associations, and antipredator responses
TLDR
The behavior of nine species of macaws, parrots, and parakeets at the Machiguenga Ccolpa, a clay lick on the Rio Manu, Peru in the dry season, suggests some continued exploitation, or a long-term memory in the birds. Expand
Parrots of the World
From the macaws of South America to the cockatoos of Australia, parrots are among the most beautiful and exotic birds in the world--and also among the most endangered. This stunningly illustrated,Expand
The effect of weather conditions on the feeding behaviour of a diving bird, the Common Guillemot Uria aalge
TLDR
Analysis of long-term data on chick provisioning and adult attendance for the study colony indicated that the observed reductions in the mean energy value of loads and the proportion of chicks attended by both adults in stormy weather, which were evident in the 1997 data, were also apparent across years.

Bamboo control of forest succession: Guadua sarcocarpa in Southeastern Peru
TLDR
It is proposed that the occurrence of bamboo-dominated forests can be explained by an interplay between mechanical properties of soils, wind disturbance, and elevated rates of tree mortality in the presence of bamboo. Expand
Geophagy among primates: adaptive significance and ecological consequences
TLDR
It is concluded that mineral supplementation, adsorption of toxins, treatment of diarrhoea and pH adjustment of the gut seem the most plausible reasons why primates engage in geophagy. Expand
