“…Population density (PD) gives us an idea about how many people inhabit in each neighbourhood. This could be a variable of interest since it has been seen to have a strong influence on feral pigeon density (Senar et al, 2009). The percentage of people over 65 years (PD > 65) was considered because this population group seems to be more likely to feed birds in urban habitats (Montalvo & Senar, pers.…”

Several invasive species have been shown to have a marked preference for urban habitats. The study of the variables responsible for the distribution of these species within urban habitats should allow to predict which environmental variables are indicative of preferred habitat, and to design landscape characteristics that make these areas less conducive to these species. The Monk parakeet Myiopsitta monachus is an invasive species in many American and European countries, and cities are one of its most usual habitats in invaded areas. The aim of this paper was to identify the main factors that determine distribution of the Monk parakeet in Barcelona, one of the cities in the world with the highest parakeet density. We defined our model based on eight preselected variables using a generalized linear model (GLZ) and evaluated the strength of support for each model using the AIC–based multi–model inference approach. We used parakeet density as a dependent variable, and an analysis restricted to occupied neighbourhoods provided a model with two key variables to explain the distribution of the species. Monk parakeets were more abundant in neighbourhoods with a high density of trees and a high percentage of people over 65 years. This is interpreted by the fact that parakeets use trees as food sources and support for the nests, and that older people often feed the species. Data support the ‘human–activity’ hypothesis to explain how invasive species can successfully establish in a non–native habitat, and stress how limiting food resources, especially food supplied by humans, may be the easiest way to exert some control on Monk parakeet populations.

“…This study led to the recommendations that, in general, population control measures that are based on eliminating individuals are not very effective, rather, as indicated by Senar et al (2009), it is better to focus on control methods based on the limiting factors of this species, that is, the availability of food and nesting areas. In order to make elimination an effective method, at least 30% of the population must be sacrificed (Senar et al 2009). Table 1.…”

The present study determined the population density of Columba livia domestica in the new market of Sincelejo, Sucre, Colombia. It is known that, when populations of this species increase excessively, a serious public health problem is created that must be dealt with in order to avoid the transmission of zoonotic diseases. In the city of Sincelejo, especially in the study area, the magnitude of this species' population is unknown, as is the case in many cities in Colombia where this bird has become a serious environmental threat. For ten continuous days, between 06:00 and 08:00, fixed point sampling was used with timed counts; likewise, measurements were taken for the noise levels found in the study area. There were no statistical differences for the population detected in each sampling site for the ten sampling days or the study sites and hours. The estimated population was 257 individuals with a SD= 10.7; the estimated density was 574 ind/km 2 ; the peak noise levels fluctuated between 68.2 and 83.5 decibels. The calculated density was lower when compared to other studies but higher than the density that has been established as harmful for this species in urban populations. During the sampling hours, the noise levels found in the population were high but tolerable. Population studies of this species in urban environments are necessary in order to implement management plans and programs that prevent the possible proliferation of zoonotic diseases.

“…En Sincelejo se mantuvo la preferencia de las palomas por la zona céntrica, evento similar a lo reportado por otros autores (Sacchi et al, 2002;Giunchi et al, 2007;Hetmañski y Jarosiewicz, 2008;Senar et al, 2009), específicamente por la zona comercial e histórica, donde se presentó el mayor número de individuos. La predilección hacia estos lugares se debe a la abundancia de negocios informales de venta de comidas y la comercialización de diferentes tipos de granos que generan desechos orgánicos que sirven de alimento a las palomas.…”

El objetivo de la presente investigación fue determinar la variabilidad genética de las poblaciones de palomas domésticas (Columba livia), utilizando genes que codifican la coloración y diseño del plumaje en Sincelejo, Sucre (Colombia). Las poblaciones, distribuidas en veinticuatro colonias, se estudiaron entre julio de 2016 y enero de 2017 e incluyeron 1402 individuos. Se evaluaron los marcadores: Patrón del plumaje, Coloración primaria, Spread y Grizzle. Los parámetros genéticos frecuencia alélica, diversidad genética y estructura poblacional fueron calculados a través del programa PopGene 1.31, la distancia genética se determinó mediante el programa FSTAT v. 2.9.3.2 y el dendrograma se realizó utilizando el programa MEGA 7. Las frecuencias alélicas obtenidas oscilaron entre 0.2290 para el alelo Checker (C), 0.1458 para el marcador T-Pattern (CT), 0.1317 para el gen Grizzle (G), 0.0882 para el marcador Ash-Red (BA) y 0.0282 para el alelo Spread (S). El coeficiente de diferenciación genética fue de 0.0148 y el número de migrantes detectados por generación fue de 33 individuos. El dendograma mostró tres grupos: uno ubicado en la zona céntrica de Sincelejo y dos grupos en la periferia. Los resultados muestran poca diferenciación genética entre las poblaciones de palomas estudiadas.
