Small birds are difficult to photograph and the smallest are even more so since they are usually hyperactive. In winter Wrens have a really tough time. When I find them it is often near to water - streams and rivers. No doubt it is food related. This individual was feeding at the waterline although I could not see the prey as it was too small. Fortunately it did a feeding loop so it gave me a chance to anticipate where it might land. Even so, in January there's not much light to stop that motion.
