Immature Great Black-backed Gull, Mississippi River, lock & dam #14, Le Claire, Iowa
Here are a couple more photos from my trip last weekend to lock & dam #14, down in Le Claire, Iowa. The goal was to practice panning with the Nikon Z6II and Sigma 150-600 lens attached. There is always a number of gulls around this area, mostly Ring-billed Gulls, but this time I found only three birds and they all seemed to be Great Black-backed Gulls. This is an uncommon species for this part of the country but I have photographed them before at this location and some other, more experienced birders than me, have documented their presence as well.
Gulls are a great subject for practice with the long lens. They fly often in circles and return over and over again during their hunt for fish, giving the photographer multiple chances to try different settings for the autofocus system and to find out what works best for a fast flying subject. It doesn’t matter how good the autofocus system on a new camera is, proper panning and handholding is still essential for a high keeper rate of sharp images. I could tell that I’m well out of shape. The keeper rate wasn’t bad but there is a lot room for improvement. The Mississippi was still covered with ice here in the Dubuque area yesterday. Once the ice breaks, which will be soon with the warm weather we have since a few days, the birds will move in and I hope my panning skills can improve with more practice down at the river…
