Reproductive biology of Nyctidromus albicollis (Aves: Caprimulgidae) in Santa Cruz, Bolivia
This study describes the first data on reproductive aspects of Nyctidromus albicollis in Bolivia by monitoring a nesting site with camera traps. The monitoring period between incubation and the abandonment of the laying site by the fledglings lasted 30 days and 236.89 h of recording were recorded with camera traps. The male was observed incubating 65.3% of the time, with a proportion of 75% during the day. The female dedicated 34.7% to incubation and did so mainly at night. The chicks hatched asynchronously on 08/28/2022 with differences between one and the other of 11 h, after 21 days one of the fledglings closely followed by one of the parents left the nest with fully developed plumage, except for the length of tail feathers. The second squab remained alone for more than 12 h and the camera trap images reveal that it was preyed upon by a green snake of the genus Philodryas.

En este estudio se describen los primeros datos sobre aspectos reproductivos de Nyctidromus albicollis en Bolivia mediante el monitoreo de un sitio de nidificación con fototrampeo. El periodo de monitoreo entre la incubación y el abandono del sitio de puesta por los volantones duro 30 días y se tuvo 236.89 h de registro con fototrampeo. Se observó al macho incubando en el 65.3% del tiempo, con una proporción del 75% durante el día. La hembra dedico un 34.7% a la incubación y lo hizo principalmente durante la noche. Los pichones nacieron de forma asincrónica el 28/08/2022 con diferencias entre uno y otro de 11 h, luego de 21 días uno de los volantones seguido de cerca por uno de los padres abandono el nido con el plumaje totalmente desarrollado, excepto por el largo de las plumas de la cola. El segundo pichón permaneció solo por más de 12 h y las imágenes de la trampa cámara revelan que fue depredado por una culebra verde del genero Philodryas.
