The wings of the world's tiniest birds are a near-invisible blur as they whizz around tourists visiting a private Cuban garden that has become a haven for the declining species.
The bee hummingbird, which measures just five to six centimeters (two inches) long, is only found in Cuba. Its losses have been huge, with the International Union for Conservation of Nature (IUCN) saying it has disappeared from many areas due to deforestation.
But in Palpite, in the southwest of the country, Bernabe Hernandez, 75, has turned his garden into a paradise for the bitty bird.
"We never get tired of it. We always discover something new!" he said as he watched two of the hummingbirds (Mellisuga helenae) zip towards a hanging water bath.
Cubans call them "zunzuncito," a word evoking the sound of the buzzing of their tiny wings, which can flap up to 100 times a minute.
When Hurricane Michelle, one of the strongest to ever hit Cuba, devastated crops and homes in the area in 2001, "the zunzuncito disappeared. There were no more flowers, many died," according to local bird lover Orestes Martinez.
Hernandez moved to the village of Palpite after the hurricane destroyed his home. The government gave him land to rebuild on the edge of the Cienaga de Zapata, the largest wetland in the Caribbean.
"I moved here, but there were no birds," he told AFP.
"So I planted a 'ponasi' to provide shade and attract some birds," he said, referring to a shrub whose fruit is sought after by birds.
He did not know that the shrub's flowers were a delicacy for bee hummingbirds, who quickly flocked to his garden, which also boasts mango, guava and avocado trees.
"When I first saw a zunzuncito, I thought it was an insect," he said.
He decided to plant more of the shrubs and his lush garden soon buzzed with hummingbirds, which nested in nearby woods.
Another hummingbird, the Cuban Emerald, which measures up to 10 centimeters, also frequents the garden, which was opened to tourists in 2003 and is now known as "The House of the Hummingbirds."
Visitors hold up bird feeders to lure the tiny birds closer.
Guides from the Cienaga de Zapata National Park, known for its diversity of bird life, with over 175 species, aided Hernandez and his wife Juana Matos with the precise mixture of water and sugar contained in the feeders.
The two have become experts in the behavior of the bird, pointing out the iridescent red head of a male bee hummingbird, who looks like he is wearing a glittery mask -- but only during the mating season.
For the amateur ornithologist Martinez, the garden is an important sanctuary for the minuscule hummingbird, classified as "near-threatened" by the IUCN, which estimates its numbers at between 22,000-60,000.
The garden helps "protect the bird. During the breeding season, the female can more easily gather food for the chicks."
