Among the most active hummingbirds at Dave and Dave’s Costa Rican Nature Park were the White-necked Jacobins…a beautiful hummer that often flares it pure white tail in a dominance display. Light is always an issue in the rainforest, so these shots were all at high ISO, especaily as I wanted a high shutter speed to freeze action. I used my custom Birds in Flight and Action modifications of Program mode, which includes a Auto ISO Minimum Shutter Speed setting to keep the shutter speed above 1/1000th. All shots were processed in Polarr.
