Tree Swallow, Green Island Wetlands, Iowa
It was a great day for bird watching in the wetlands today. Many more ducks were present than during my last visit two weeks ago. And there were quite a few bird lovers out there, everybody in their car and with binoculars or cameras sticking out the window. I saw a lot Blue-winged Teals, Bufflehead, Hooded Mergansers, Northern Shovelers, and one pair of Green-winged Teals. I also got information about a Cinnamon Teal, but I was not able to locate the bird. It would have been a “first” for me in the Green Island Wetlands. In addition the first flycatchers have arrived and I saw an Eastern Phoebe and a Kingbird.
We had still some frost last night but the sun this morning heated up the air very quickly. This brought out the insects and large groups of Tree Swallows tried to catch them. They used the shrubs along the edge of the water to perch and to rest for brief moments. The Tree Swallows return to their nesting grounds earlier than any other American swallow. The ones I saw today were probably just on their way through. Their summer habitat stretches as far as northern Canada.
The warm air above the cold water created quite a bit of heat shimmer again. I was shocked how much it effected the sharpness today. Although the light was crisp and many bird species provided good contrast, normally easy to focus on, but my keeper rate was not very good.
