This series of images of a great kiskadee (coughing up a ball of what I assume are insect exoskeleton bits), was taken from the verandah of Asa Wright Nature Centre in Trinidad. In the last image, the bird looks almost relieved, and perhaps a bit embarrassed that the whole episode was captured on camera.
There are days (like today) when I'd like to be able to cough up a huge ball of stuff, if it would make everything better. On second thought, maybe there are better ways to make oneself feel better. Like playing a softball double-header. Think I'll try that instead...
