An
extensive analysis of the relationships of nine-primaried passerines
(tanagers, New World warblers, sparrows, buntings, etc.) by Barker et
al. (2013) found firm evidence of evolutionary sets of "tanagers" that
arose on islands in the Caribbean. Indeed, those authors even went so
far as to propose four new families from this radiation [Spindalidae, Nesospingidae, Phaenicophilidae, Calyptophilidae].
Initially cautious, I placed these together in 2016 in just one family;
now, following Winkler et al. (2015), I've now elevated all Families as
Barker initially proposed.
Barker et al. (2013)
stated that among the Caribbean lineages "the only truly unambiguous
relationship is the unity of the Hispaniolan endemics Phaenicophilus, Xenoligea, and Microligea." The genus Phaenicophilus holds the two palm-tanagers — Black-crowned Palm-Tanager P. palmarum (left in a fine photo by Murray Lord) and Gray-crowned Palm-Tanager P. poliocephalus.
Black-crowned Palm-Tanager is one of the most ubiquitous of
Hispaniola’s endemics, present in just about any wooded habitat in the
Dominican Republic and the eastern half of Haiti. Gray-crowned
Palm-Tanager is Haiti's lone avian endemic. It is still relatively
common in the forest of the Tiburan peninsula where it occurs from
sea-level to the highest forested peaks at 2400m. It is said to be
especially common in the karst limestone rainforests of the Macaya
Biosphere Reserve, a loosely protected national park high up in the
Massif de la Hotte (Keith et al. 2003).

Despite the English names we use for the two palm-tanagers, these are not
tanagers. They've been called "tanagers" in the past, and so we can
continue to do so. We just need to recognize that there are many birds
called "tanagers" that are now classified in other families [to use
just one example, Scarlet, Summer, and Western Tanagers, familiar to
North American birders, are actually in the cardinal/grosbeak family
Cardinalidae]. This Black-crowned Palm-Tanager (right) is backlit against the thick morning fog in the cloud forest at Cachote, Dominican Republic. |
The
final two members of this Family are traditionally called "warblers,"
but they are not closely related to the Parulidae. These are
Green-tailed Warbler Microligea palustris and White-winged Warbler Xenoligea montana. Green-tailed Warbler — better called Green-tailed Ground-Tanager
(below left in a photo by Murray Lord) — joins mixed species flocks in
a variety of woodlands (thornscrub to broadleaf), primarily in the
understory on montane woodlands in the Dominican Republic (its range
quite limited in Haiti). White-winged Warbler — which might be called Hispaniola Highland Tanager
(below right, another Murray Lord shot) —occurs in both Hispaniola
nations, but its range is limited to humid montane broadleaf and wet
karst limestone forests (Keith et al. 2003). It is rather little-known;
the first nest was only discovered in 2004. |

Photos: Murray Lord photographed the Black-crowned Palm-Tanager Phaenicophilus palmarum, Green-tailed Warbler (Ground-Tanager) Microligea palustris and White-winged Warbler (Hispaniola Highland Tanager) Xenoligea montana during a visit to the Dominican Republic between 26-28 Apr 2009. The backlit Black-crowned Palm-Tanager was at Cachote reserve, Dominican Republic, in Feb 2017.

Bibliographic note:
There is no "family book" per se. The species in this set have been
previously covered in books on tanagers, such as Isler & Isler
(1987), or the applicable chapters on "warblers" or "tanagers" in the Handbook of the Birds of the World series.
