Capsule We suggest the existence of colour-based selection processes on juvenile Feral Pigeons in an urban environment. Aims To investigate whether the colour or pattern of a fledgling affects its probability of survival to adulthood. Methods We determined the frequency of colour morphs of young and adult birds on 20 days in 1996 by recording the coloration in a population of Feral Pigeons in Vienna, Austria. Results Over 57% of the Feral Pigeons were of colorations also shown by wild Rock… Expand
Eumelanin-based colouration reflects local survival of juvenile feral pigeons in an urban pigeon house
This study tested whether eumelanin-based colouration could be linked to survival in two urban populations of the feral pigeon Columba livia and found that darker juveniles had a higher local survival probability than light ones, suggesting the existence of colourand/or density-dependent selection processes acting on juvenile feral pigeons in urban environments.

A potential role for parasites in the maintenance of color polymorphism in urban birds
Paler morphs did better than darker morphs in moderately urbanized environments but were negatively affected by increasing urbanization, while darker Morphs performed equally in all environments suggests that melanin-based coloration might reflect alternative strategies to cope with urbanization via different exposure or susceptibility to parasites.

Transcontinental genetic inference of urban pigeon populations using phenotypic markers
The results showed a higher genetic diversity in populations from northern South America with respect to the one from Western Europe, although the differentiation among cities was low, and a significant correlation between genetic and geographic distances was not found. Expand
Rock - Pigeons in Some Parts of Bangladesh
Out of 492 rock pigeons the highest percentage were shown in blue bar (74.59) then blue checker (10.77) and highest pigeons, male and female were found in Ishwardi and lowest in Sylhet of Bangladesh. Expand
Pigeons and People: resource ecology and human dimensions of urban wildlife
It is suggested that feral pigeon populations are largely dependent on the availability of anthropogenic foods, and reducing the food provided by people may limit feral pigeons populations. Expand
Becoming Citizens: Avian Adaptations to Urban Life
Although cities have existed for some millennia, it has been only in the last few centuries that they have expanded to become a dominant feature of the landscape. Their growth displaces originalExpand

This study provides a rare empirical link, in a vertebrate predator-prey system, between a predator's foraging behavior and direct measures of its reproductive fitness, and finds that pigeon color polymorphism is maintained through negative assortative mating. Expand
EVOLUTION Evolution of life in urban environments
BACKGROUND: The extent of urban areas is increasing around the world, and most humans now live in cities. Urbanization results in dramatic environmental change, including increased temperatures, moreExpand
Evolution of life in urban environments
The suite of pressures that urban environments exert, the ways in which species may (or may not) adapt, and the larger impact of these evolutionary events on natural processes and human populations are reviewed. Expand
Pigeons and people: mortal enemies or lifelong companions? A case study on staff perceptions of the pigeons on the University of South Africa, Muckleneuk campus
Pigeons have been a part of our lives for as long as we can remember. Some people view them with joy, others disdain. Regardless of the perception, control measures are often implemented against theExpand


Gefiederfärbungen bei der Straßentaube (Columba livia)
Feral pigeons probably show greater variation in plumage colouration than any other free-living bird species. The different colour patterns are linked to ethological and physiological characteristicsExpand
Age-related feeding site selection in urban pigeons (Columba livia): experimental evidence of the competition hypothesis
This study examined the age-specific feeding site selection and its ecological mechanism in free-ranging Rock doves and found adults were consistently found more often than expected in the most rewarding feeding site, while juveniles were more often found in suboptimal sites. Expand
Large scale production of White Carneaux pigeons with reliable pedigrees: reproductive characteristics and parent-offspring identification.
The loft-breeding method was used for the production of 439 White Carneaux pigeons with reliable pedigrees and had the advantages of lower cost and reduced management problems, while the large outdoor lofts allowed the pigeons exercise, group social interactions, and exposure to natural environmental conditions.

The Rock Dove on Nolsoy, Faeroe Islands is polymorphic, the mutants showing a tendency towards melanism and having mantle and wing-coverts spotted black, and the population is greatly reduced by severe winter weather, and is now at a very low ebb. Expand
Competition for Food in Urban Pigeons: The Cost of Being Juvenile
The relationship between competitive foraging ability and age-specific mortality was examined in a free-ranging Rock Dove population and it was suggested that differential mortality of juvenile and adult pigeons could in pail arise from differences in competitive abilities over food. Expand
Transmission of antibodies to Chlamydia Psittaci and Coxiella Burnetii through eggs and “crop milk” in pigeons
Young semi-domesticated pigeons captured or hatched from eggs gathered in Bratislava during 1989–1991 were examined for complement fixing antibodies to Chlamydia psittaci and agglutinating antibodiesExpand
Quantification of the immunoglobulin classes IgG and IgA in the young and adult pigeon (Columba livia).
Serum IgG concentrations in relation to age showed a similar pattern in pigeons to that in chickens, and the same applies to the transfer of maternal immunoglobulins via egg. Expand
