Singapore last hosted the World Stamp Exhibition in 1995 and the inaugural World Stamp Championship in 2004. Gathering the experiences of both exhibitions, the Association of Singapore Philatelists (ASP), with effort to commemorate Singapore's golden jubilee in 2015, managed to successfully bid for the hosting rights of another World Stamp Exhibition in 2015, with support of the Fédération Internationale de Philatélie (FIP - International Federation of Philately). With the theme "Stamps for all Ages", 4 sets of past issues, with designs from the "1955: Queen Elizabeth II Definitives", "1962 - 1966: Fishes, Orchids and Birds Definitives" (1st series), "1960: National Day" and "1970: Osaka Expo" are selected to revive the memories of collectors, as well as to showcase the developments that Singapore had achieved through the years.

In this year's first series, 2 designs from the "1962 - 1966: Fishes, Orchids and Birds Definitives" are chosen.

The Yellow-breasted Sunbird (Leptocoma jugularis) is probably the commonest Sunbird in Singapore, especially near the coast, and is a frequent visitor to gardens. It probes into flowers in quest of nectar and insects with its long and slender tongue. It is particularly attracted to red flowers and is shown on the stamp hovering before Russelia juncea (commonly known as the firecracker plant). When it takes to flight, it invariably utters a shrill "chip, chip, chip", resembling the sound produced by the knocking of two pebbles. Its nest is bottle-shaped and consists of dead leaves, fibres and lallang, with the entrance at one end sheltered by a projecting eave. The nest hangs from a twig or from any permanently undisturbed structure of wire or rope.

The White-bellied Sea Eagle is a common bird and is found around our coastal areas and on the off-shore islands. It usually soars in circles at a great height and feeds on sea-snakes, fish and crabs. Crabs are dropped from a height onto rocks in order to break the shell, but this is not a common behavior. Nests are built high up in a tall tree and are used year after year with constant additions which result in the development of large and conspicuous nests. This Eagle is a common sight around our coasts and may sometimes be seen hovering the skies at Labrador Park. Threatened by habitat loss which removes suitable nesting sites and prey, however, in Singapore, their numbers appear to be stable with a stronghold around the water catchment areas.
