“…wild type); 2) checker (a checked mantle with moderate black spots); 3) t‐pattern (a black mantle with small grey marks); and 4) spread (a completely black plumage). This classification reflects genetic differences at two multi‐allelic loci (Johnston and Janiga 1995, Haag‐Wackernagel et al 2006), thus defining colour morphs (Roulin 2004). Although juveniles are slightly darker before their first moult, the morph of an individual remains the same throughout life (Johnston and Janiga 1995), an observation that was confirmed by photographs taken at different ages in captivity (Jacquin unpubl.).…”

Urbanisation introduces deep changes in habitats, eventually creating new urban ecosystems where ecological functions are driven by human activities. Th e higher frequency of some phenotypes in urban vs rural/wild areas has led to the assumption that directional selection in urban habitats occurs, which may thereby favour some behavioural and physiological traits in urban animal populations compared to rural ones. However, empirical evidence of directional selection on phenotypic traits in urban areas remains scarce. In this study we tested whether eumelanin-based colouration could be linked to survival in two urban populations of the feral pigeon Columba livia . A number of studies in diff erent cities pointed out a higher frequency of darker individuals in more urbanised areas compared to rural ones. To investigate whether directional selection through survival on this highly heritable trait could explain such patterns, we conducted mark -recapture studies on two populations of feral pigeons in highly urbanized areas. We predicted that darker coloured individuals would exhibit higher survival and/or philopatry (integrated into ' local survival ' ) than paler coloured ones. No diff erence in local survival was found between adults of diff erent colouration intensities. However, on one site, we found that darker juveniles had a higher local survival probability than light ones. Juvenile local survival on that site was also negatively correlated with the number of chicks born. Th is suggests the existence of colourand/or density-dependent selection processes acting on juvenile feral pigeons in urban environments, acting through diff erential mortality and/or dispersal.

“…15; see Different forms of melanism). According to research in Vienna, ash-red barred juveniles have a high probability of reaching adulthood, while ash-red juveniles with chequer or T-pattern chequer have a rather low survival rate (Haag-Wackernagel et al 2006). This is remarkable as eumelanised juveniles with chequer or T-pattern chequer wings possess a higher success rate, compared to their barred counterparts.…”

“…obs.). In Vienna, for example, <5% of the city's feral population is ash-red (Haag-Wackernagel et al 2006), which appears unexpected given that the mutation is dominant in inheritance over the black / grey wild phenotype. In fact, it is dominant and sex-linked, thus all male offspring (= 50% of all offspring) of an ash-red female crossed with a wild phenotype male are ash-red.…”

“…It appears that the plumage colour of juvenile Feral Pigeons is associated with features that influence its survival to adulthood in an urban environment. Strongly melanistic fledglings are more likely to attain adulthood, compared to the wild phenotype (Haag-Wackernagel et al 2006). There is also some evidence in Feral Pigeons that melanistic males have a longer breeding season and are more fertile than the wild phenotype (Murton et al 1973).…”

“…El tipo de coloración conocido como azul barra (plumaje azul grisáceo), con dos barras negras paralelas en cada ala es considerado el fenotipo silvestre. Los colores del plumaje y patrones de alas reportados en palomas son producidos por cuatro sistemas de alelos primarios: Checker, Ash-Red, Grizzle y Spread Son escasas las investigaciones que en coloración y diseño del plumaje hasta el momento se han realizado poblaciones de palomas 1,2,[10][11][12] En el presente trabajo se estudió la diversidad genética de la paloma doméstica (Columba livia) en Bogotá, utilizando genes que codifican la coloración y diseño del plumaje en 2903 palomas de Bogotá distribuidas en 28 colonias.…”

Objetivo. Caracterizar genéticamente las poblaciones de paloma doméstica (Columba livia) en Bogotá, Colombia, utilizando genes que codifican la coloración y diseño del plumaje. Materiales y métodos. Se realizaron muestreos aleatorios en 28 colonias en la ciudad de Bogotá en el periodo comprendidos entre enero y junio del año 2014. Mediante excursiones urbanas, observación directa y registros fotográficos se estudiaron 2903 palomas. Se utilizaron los marcadores autosómicos que codifican la coloración y diseño del plumaje: Grizzle (G); Spread (S); Checker (C), y el locus ligado al sexo Ash-Red (B). Los parámetros genéticos: frecuencia alélica, diversidad genética, equilibrio Hardy-Weinberg y estructura poblacional fueron calculados a través del programa PopGene 1.31; la estructura genética y la distancia genética se evaluaron mediante el programa FSTAT v. 2.9.3.2. La elaboración del dendrograma se realizó empleando el programa MEGA 5. Resultados. Los marcadores que presentaron las mayores frecuencias alélicas fueron Checker y Spread. Se registraron valores poco significativos de variabilidad genética y una escasa diferenciación genética entre las poblaciones, acompañado de un elevado flujo génico; se observó un exceso de heterocigotos; a esto se le suma la ausencia de equilibrio Hardy-Weinberg y se reportaron valores bajos de distancia genética. Conclusiones. Las poblaciones se encuentran muy relacionadas genéticamente, situación que puede obedecer a la cercanía geográfica existente entre ellas, lo que ha favorecido el intercambio genético
