Bahamas cruise resulted in sightings of flying gems

Continuing to bring you some vintage columns, I dug deep into my archives. I've traveled outside the United States on only one occasion from Jan. 22-24, 1999, during a family vacation. Sightseeing and shopping took a backseat to birding during a three-day cruise in the Bahamas. I fully documented my sightings in a "Feathered Friends" column published Feb. 14, 1999. Two scheduled shore excursions during the cruise gave me opportunities to search for birds. Two hummingbird species can be found in the Bahamas. The Cuban emerald, as its name suggests, is found in Cuba. It's also found on several islands in the Bahamas. These dazzling birds are found in thickets and woodlands, as well as parks and gardens. Another hummingbird species, the Bahama woodstar, is found nowhere else in the world. Without much difficulty, I observed both species during my visit to the Bahamas. My observation of Cuban emeralds took place on Castaway Cay, a small island owned by Disney and reserved for use by those traveling aboard its cruise ships. Much of the island had been kept in a natural state with walking trails perfect for looking for birds. While others enjoyed the beach, I set off with my binoculars on the trails. My mother and I observed a pair of Cuban emeralds that appeared to be a mother and her male offspring. On two occasions, we watched the female approach the young male for a feeding session. The young bird opened his bill in a wide gape and the female plunged her own long bill into his throat. The spectacle looked rather fearsome, but that's how hummingbirds feed their young. I've observed one of our native ruby-throated hummingbird feeding her young in the same manner. Experts who have researched hummers insist there's no danger that a mother hummingbird will skewer her offspring. The young male being fed put on quite a show. He appeared almost completely lacking in fear and allowed me to approach within inches of his perch. At times, he also exhibited his own curiosity and buzzed around my head and face for a better look of his own. His mother, not quite as confiding, kept her distance. She perched on branches about 15 feet off the ground. She observed us, but she never descended to feed the young male unless we withdrew to a comfortable distance. I learned later that my brother and sister-in-law saw some Cuban emeralds at another location on the island, leading me to suspect that the Cuban emerald may be quite common on Castaway Cay in the Bahamas. Male Cuban emeralds sport an iridescent green throat and breast with a long forked tail, white undertail feathers, and a long thin bill that is black on top and reddish-pink on the underside. Females look similar to males except with green upperparts along with a grayish throat and breast, and a slightly shorter and less forked tail. The term "emerald" describes many different species of hummingbirds. In the Caribbean, this family includes Hispaniolan emerald and Puerto Rican emerald. These hummingbirds belong to the genus Chlorostilbon, which is Greek for "green glitter," a perfect description of the metallic green appearance of their feathers. Since my writing of the original column, experts have reconsidered the classification of the Cuban emerald. Based on a molecular phylogenetic study published in 2014 and a 2017 publication, the North American Classification Committee of the American Ornithological Society moved the species to the resurrected genus Riccordia. The Cuban emerald's scientific name is now Riccordia ricordii. Prior to seeing the Cuban emeralds I got a brief but close look at a male Bahama woodstar visiting hibiscus and other flowers in a garden surrounding a swimming pool at a resort in Nassau, the capital of the Bahamas located on New Providence Island. The Bahama woodstar bears a resemblance to our own ruby-throated hummingbird. Male Bahama wood stars boast a reddish-purple throat, green upperparts and a white breast bordered by a tinge of rufous. The bird's forked tail feathers are also trimmed with rufous color. Males and females have a white spot behind each eye. They also have black bills that curved downward slightly at the tip. The Bahama woodstar, which is roughly the same size as a ruby-throated hummingbird, is a member of the genus Calliphlox, which is Greek for "beautiful flame." Since my original writing of this column, the classification of the Bahama woodstar changed after a 2014 study. A former subspecies of the Bahama woodstar has been made its own species. The Bahama woodstar itself was moved into a new genus and given the scientific name Nesophlox evelynae. That former subspecies was upgraded to full species status and is known as the Inagua woodstar (Nesophlox lyrura), also called the lyre-tailed hummingbird. The species is endemic to the two islands of the Inagua district of the Bahamas. It's the Bahama woodstar that occurs in Nassau, so the species I saw in 1999 was truly the Bahama woodstar. The good news is that if I ever travel to the Great or Little Inagua islands in the Bahama archipelago I will have a chance to add a third species of Bahama hummingbird to my life list. There are many other species of woodstars, including the little woodstar of South America, the purple-throated woodstar restricted to the west slope of the Andes in Colombia and Ecuador, and the endangered Chilean woodstar. There are about 360 species of hummingbirds, all found in the New World and reaching their greatest diversity in Central and South America. Both Cuban emeralds and Bahama Woodstars have strayed into nearby Florida, so it is possible to observe these two species outside of the Bahamas. Experts have speculated that the Inagua woodstar had very likely also strayed into Florida. I'll always remember my trip to the Bahamas and the opportunity to chase after zunzún, which is a Spanish word, particularly used in the Caribbean, for hummingbird. I greatly enjoyed my observations of the two hummingbird species I observed in the Bahamas. These sightings remain among my most memorable in my nearly four decades of birding. ••• Bryan Stevens has written about birds, birding and birders since 1995.
