tailieunhanh - Ecomorphological associations and abundance of birds across the agricultural landscape of Pothwar Plateau, Pakistan

Some species are exceptionally common in landscapes heavily impacted by humans, such as agricultural lands. This study was carried out over a period of 2 years (July 2012 to June 2014) in the arid agricultural landscape of Pothwar Plateau, Pakistan, to identify adaptations that govern bird distribution and abundance across 2 different cropping systems associated with differences in water availability. We used regular surveys and foraging observations to quantify species abundance, distribution, and habits. We then examined morphological correlations with ecological attributes. We found the following: (1) larger birds tended to spend more time in trees; (2) birds with small beaks and relatively long wings more commonly forage on the ground; (3) birds with narrow and long beaks and long tarsi were more likely to be insectivorous in habits. |
