Parque Nacional Yanachaga-Chemilln, Sector El Paujil
These active little "flycatchers" (now in Tityridae) are usually conspicuous components of midstorey flocks, constantly changing perches and fanning their tails.
But one day while I was having lunch, I noticed a family, two adults and one immature, sitting in a small tree over a stream, vocalizing a lot, but hardly moving. Over nearly an hour, they never left the tree, and when I was back on that same trail three days later, the three of them were still in that tree!
The immature was clearly capable of flight, so I wonder what that was about...
