Avian ecology and behavior

Due to the widespread decline of bird populations that inhabit wetlands and the secretive nature of birds, detailed information on habitat use is often difficult to obtain.Pardirallus sanguinolentus Swainson, 1838 is a little studied bird that inhabits wetlands.The reported data about this species are limited to morphological descriptions and aspects of its ecology.However, there is no scientific literature related to habitat use, habitat selection or details of its behavior.Therefore, the goal was to contribute to knowledge about habitat selection and some aspects of its ecology.The work was carried out in the Putemún wetland (42° 25' 37.90" LS and 73° 44' 47.20" LW) under low tide conditions.Habitat selection was calculated using the Manly Selection Ratio after obtaining the home range of the individual studied with the Kernel estimator.Waterbodies were the most important habitatfollowed by muddy beaches at low tide and the third most important habitat component was muddy beaches covered with herbaceous vegetation.The first two types of coverage may have been preferred due to the presence of good quality food (feeding was the most frequent activity in these types of coverage).The species was very easy to detect and observe, and was very active throughout the day, contrary to what was previously reported.
