Gorgeous colors with the armor of the Spindalis family Spindalidae

This (left) is the colorful male Jamaican Spindalis. It is one of four species of genus Spindalis — once called “Stripe-headed Tanagers” — that comprise the heart of this newly proposed family Spindalidae.

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 2014 in just one family. Now, following Winkler et al. (2015), and AOU and Clements checklists, I adopt all the proposed families.

Despite the English names we use, these are not tanager. Yet most of them have 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.

The four species of Spindalis in genus Spindalis are Jamaican S. nigricephala, Hispaniolan S. dominicensis, Puerto Rican S. portoricensis, and Western S. zena. More many decades they were lumped together as one widespread Caribbean species, and was known as “Stripe-headed Tanager,” until split on morphological and vocal grounds by Garrildo et al. (1997).

Most Spindalises are resident within their namesake islands, generally preferring open forests, gardens, and scrub habitats. Western Spindalis (right, male above, female below) is more widespread, occurring in the Bahamas and the Turks and Caicos Islands, on Cozumel Island off the Yucatan Peninsula of Mexico, on the Cayman Islands, and in Cuba. It is a rare visitor of extreme southern Florida, but a pair of the Bahamian subspecies S. z. zena successfully nested in 2009.

All the four members of genus Spindalis are sexually dimorphic, with colorful males — with much orange and black — and duller females that wear shades of brown or gray. Western Spindalis is a dramatic example. Yet, despite the male’s bright colors, they can be hard to spot within foliage, and in my experience the pairs or small groups seem constantly on the move.

Spindalises are somewhat omnivorous with reasonably heavy bill, but feed heavily on fruit or (seasonally) insects. They build cup-like nests.
