Примечания
This recording highlighted various vocalizations given during what appeared to be aggressive interactions between birds foraging over a swarm of Eciton burchelli in the understory of good terra firme forest with scattered palm trees along the trails through the forestry study plot. These birds were well seen as they chased each other around through the understory, and when recorded in the first part they were probably 12 meters away and <1 meter above the ground. The bird highlighted in the second part of this recording was seen only briefly as a small antbird as it perched about 1 meter up on small stems in the undergrowth and initially about 12 meters away but it later approached to a distance of only 6-8 meters from me (when I overloaded a few calls). After, it began moving off. There were at least six Gymnopithys rufigula, two or three Pithys albifrons, and one Dendrocolaptes picumnus in this aggregation. Most if not all of these vocalizations were given by the Gymnopithys. The Pithys were generally pretty quiet. I saw a least one churring bird that had its interscapular-patch flared. Essentially overcast, intermittently breezy, 77° F. Equipment Notes: Sennheiser powered using phantom power and with filter in flat position and attenuator off for all recordings. Nagra input set at 2 mV / Pa and low-pass filter in flat position unless noted otherwise.
