We walked (and drove) the La Gamba road near the entrance to Esquinas (Cathy pointed out I've been mis-spelling it this whole time). It's a relatively well known road on the CR birding circuit. We hadn't gone far before we found a pair of Slaty-tailed Trogons. I think some of the group spotted a nest hole as well.
I'm not sure what the definition of a tyrannulet is, other than random small flycatcher. They don't seem all that related. First a Mistletoe (Paltry) Tyrannulet, one of few birds with strong edgings to the wing coverts but lacking the end edgings to make an actual wingbar
A Yellow-bellied Elaenia was a size larger
We spent a good amount of time with some fruiting trees that had attracted both hummingbirds as well as a flock of Crimson-fronted Parakeets
We walked past a large pasture which had some distant Fork-tailed Flycatchers as well as more Red-breasted Blackbirds and various herons as it got wetter. A caracara perched up nicely, though it was hard to find a hole in the brushy stuff along the road to get a clear view.
We drove farther, stopping at a field where Vernon frequently found Ruddy-breasted Seedeaters. Some of us walked over to get the sun at a more advantageous view.
We ended the day at another stakeout, this time for a pair of Rusty-margined Flycatchers, a bird that was only relatively recently discovered to regularly cross the border from nearby Panama.
You can see how easy it would be to blow it off as a Social flycatcher.
