Abstract:
TiF Update February 3
Fluvicolinae: The Fluvicolinae have been rearranged based on Fjeldså et al. (2018). Although their phylogeny seems generally more reliable than what I cobbled together from previous work, some of the nodes are still poorly resolved. I have mostly followed their Figure 2. However, although their work suggests that Empidonax is not monophyletic, I have not made changes to Empidonax due to some weakly supported nodes.
I have carved up Xolmis. To do this, I moved the Black-and-white Monjita, now Heteroxolmis dominicanus, to Heteroxolmis and the Fire-eyed Diucon, now Pyrope pyrope, to Pyrope. I've also moved the Black-crowned Monjita, Neoxolmis coronatus, Rusty-backed Monjita, Neoxolmis rubetra, and Salinas Monjita, Neoxolmis salinarum, to Neoxolmis from Xolmis. Finally, the Gray Monjita, now Taenioptera cinerea, has been placed in Taenioptera.
Finally, there are some splits. Darwin's Flycatcher, Pyrocephalus nanus, the extinct San Cristobal Flycatcher, Pyrocephalus dubius, and Scarlet Flycatcher, Pyrocephalus rubinus, are split from the Vermilion Flycatcher, now called Pyrocephalus obscurus. See Carmi et al. (2016).
Further, the Blackish Chat-Tyrant, Ochthoeca nigrita, and Maroon-belted Chat-Tyrant, Ochthoeca thoracica, have been split from the Slaty-backed Chat-Tyrant, Ochthoeca cinnamomeiventris, based on a combination of Fjeldså et al. (2018), Ridgely and Greenfield (2001), Hilty (2003), and Garcia-Moreno et al. (1998).
