Very poor technical quality (the photo is from a video-camera and was taken under poor light conditions) but it is extremely difficult to get a glimpse of cuckoo chicks, not to speak about those in tropical habitats! For details see: Grim T. 2008: Begging behavior of the fledgling rusty-breasted cuckoo (Cacomantis sepulcralis). The Wilson Journal of Ornithology 120(4): 889–892.
