This is one of the two that appeared in the Trumpet tree (Tabebuia rosea) outside one of my bedrooms. The other one was at a different spot and soon disappeared from view. See if you hear the mumbling of the juvenile at the beginning of the video (Do not get mix up with the chirping of a Brown-throated Sunbird). Observe how it used its tongue to probe for the presence of preys in between pecks.
