NOTES: Apparently four birds, some of which were well seen, perched 40 meters away and 40 meters up in tops of canopy trees about the same level that we were in the tower; this was recorded following some whistling, but it was unclear whether the birds were reacting to us or a second pair calling in the distance; thin, scattered clouds, trace breeze, mid-80s.
ML: Subject changed from Sirystes sibilator to S. subcanescens to reflect current taxonomy. -Matt Medler, 9 Dec 2014.
