Birdfinding.info ⇒  This remarkable miniature species is rare and declining, and may qualify as endangered, but it can still be found reliably at a few sites.  The easiest place to see it is the home of Bernabe Hernández Ulloa (a.k.a. Casa del Zunzun) in the village of Pálpite, about 5 km north of Playa Larga at the eastern edge of the Zapata Swamp.  It can also be seen reliably east of Playa Larga at Bermejas Wildlife Refuge, and somewhat less reliably within Playa Larga proper.  There are also two well-known reliable sites within Península de Guanahacabibes National Park: María La Gorda and La Berraco.  In the far east, known sites include the Recreo Trail in Alejandro de Humboldt National Park and Siboney, east of Santiago de Cuba.

Bee Hummingbird

Mellisuga helenae

Endemic to Cuba and the Isle of Youth, where it occurs in open woodlands, forest edge, scrub, and gardens.

Current distribution is patchy following long-term declines.  Populations remain in at least four areas: (1) westernmost Cuba in Península de Guanahacabibes National Park; (2) the mountains of Pinar del Río and Artemisa; (3) the Zapata Swamp region of southern Matanzas; and (4) easternmost Cuba, from eastern Holguin and Santiago de Cuba east throughout much of Guantánamo Province.  Its current status on the Isle of Youth is uncertain.

Wanderers are sometimes recorded away from the known populations, and could turn up anywhere in Cuba.  In recent years most such records have been along the northern coast from Havana to the Varadero Peninsula, with a few in central Cuba at heavily visited sites including Topes de Collantes National Park, Cayo Coco, and La Belén.
