I think my 3rd lifer on the trip was this black-and-yellow silky. In some books the silkies are referred to as silky-flycatchers.
The other silky-(flycatcher) is the Long-tailed.
The female is perched on the branch above the male in the next pic.
Of course true flycatchers don't always flycatch. Mountain Elaenias also like fuchsia fruit.
Next is a Yellowish Flycatcher, one of 3 empids we don't have that can be seen in CR. It certainly has the appearance of a bird in the Cordilleran/Pacific-slope (formerly Western) group given the warm colors and strong teardrop white eyering.
Dark Pewee is nearly a Costa Rican endemic, just barely getting into Nicaragua and Panama.
Torrent Tyrannulet is a unique little bird found along the rapids.
