In the UK, housing developers make contributions to a fund, known as Section 106 funds, for the purposes of financing urban art. Cambridge City Council came up with the brilliant idea of making an allocation to build a Swift Tower on Logan's Meadow Nature Reserve (Pye Fen) which would be not only an attractive piece of static urban art, but also a dynamic piece of living kinetic art as the Swifts display in the summer with their spectacular screaming flypasts. Andrew Merritt, an upcoming young London artist was commissioned to produce a range of designs, one of which, inspired by the African sun, was chosen by a committee of local councillors and Swift experts Jake Allsop and Dick Newell.
The African Sun comprises 221 boxes held together in a supporting steel framework. Each box can be removed individually for maintenance purposes. The boxes, made of 20mm thick treated pine, are 22cm x 22cm in cross section and with lengths ranging from 50 to 90 cm, so there is plenty of space inside each one for nesting Swifts.
However, although the 221 boxes provide a stunning visual effect, it would not be sensible to have such a large number of identical front entrances.
In order to attract the birds, a 'bird scarer' device, programmed with Swift calls, will be used. It may well take more than one season to attract the birds, but once the first occupants are established, the colony should grow steadily through the years, providing a sensational attraction for Cambridge residents and visitors.
Local school children are involved in the project with a range of activities, including feathering nest concaves for the tower (see project at Milton Road Primary School).
