I arrived along the sand soil Cerrado dry scrub trail at 16h30. As I was there the Frok-tailed Flycatchers became or abundant perched everywhere. Near 17h40- the birds were clearly grouping on the talles dispersed trees. Other flicks started flying in- all in the same direction N. around 5h55 the flocks- each 50-100 birds started flying off in tighter groups and flying hi up and out of sight. By 18h00 there was not a single Fork-tailed Flycatcher in the area. Still 20 minutes until sundown- thought slightly cloudy
