The Blue-tailed Bee-eater (Merops superciliosus/philippinus)
This is a bird which breeds in sub-tropical open country, such as farmland, parks or ricefields. Like other bee-eaters it predominantly eats insects, especially bees, wasps and hornets.
They look out for suitable prey from a tree branch or high wire (about 7m and above) then swoop down onto it and snap up their victims. To get rid of the sting, the insect is vigorously whacked against the perch or simply squeezed to get rid of the venom.
