The white-necked jacobin (also known as the great jacobin or the collared hummingbird) was just one of the many beautiful hummingbirds that I saw while in Trinidad at the Asa Wright Nature Center. This is the male of the species. The females are more uniformly green. A hummingbird’s wings can flap at up to 80 times per second, so I used a reduced flash setting to help freeze the action, with only slight ghosting of the wingtips from ambient light.
