Abstract
<p><strong>Objective. </strong>Population assessment of <em>Milvago chimachima</em> (Falconidae), commonly known in Spanish as <em>pigua</em>, is a raptor species occurring in the urban area of Sincelejo, department of Sucre, Colombia. <strong>Materials and methods</strong>. Population density was calculated using a line transect. Knowledge on feeding and reproductive behavior was based on fixed-point observations. The home range of the species in the study area was estimated using parallel line transects after marking three individuals. <strong>Results</strong>. The obtained density was 4.9 individuals/Km<sup>2</sup> and the home range was between 1.43 and 1.88 Km<sup>2</sup>/individual. <strong>Conclusions</strong>. The availability of preys like rats and mice, as well as carrion and organic waste of the city can influence the presence of the bird, although its density is comparatively low.</p> <p><strong>Key words: </strong>abundance,<em> </em>Colombia, density,<em> </em>home range,<em> Milvago chimachima, </em>Sincelejo, urban area.</p><br />

Summary
Aspectos de la densidad poblacional e historia natural de Milvago chimachima (AVES: Falconidae) en el área urbana de Sincelejo (Sucre, Colombia). Evaluación poblacional de Milvago chimachima (Falconidae), comúnmente conocida como pigua, especie de ave rapaz con ocurrencia en la zona urbana del municipio de Sincelejo, departamento de Sucre, Colombia. Utilizando transecto lineal se calculó densidad poblacional, con puntos fijos de observación se realizaron algunas anotaciones sobre comportamiento alimentario y reproductivo, mediante transectos lineales paralelos se calculó, previa marcación de tres aves, el área de acción que esta especie posee en la zona de estudio. La densidad obtenida fue de 4,9 ind./km, el área de acción calculada estuvo entre 1,43 y 1,88 km2/ind. Palabras clave: Milvago chimachima, densidad, abundancia, área vital, zona urbana, Sincelejo, Colombia
