'An ashram for the hummingbird': the Trinidad haven for world's tiniest bird

Theo and Gloria Ferguson have created a garden specially designed to attract hummingbirds - and hundreds visit daily

At the foot of Theo and Gloria Ferguson's property stands a giant silk cotton tree. Reminiscent of those enchanted species in children's fables, this ancient sentinel's huge varicose limbs yawn upwards and outwards, towards a canopy of leaves that scratch the sky. Eight adults linking arms would struggle to encircle its vast girth, proof of the aeons it has stood guarding the edge of Trinidad's Maracas valley.
