BEFORE, DURING, AND AFTER

Pair of Bald Eagles, Mississippi Valley, Green Island Wetlands, Iowa

Shortly after I started shooting pictures of this pair of Bald Eagles the female left the tree. At that time I didn’t know it was the female. She returned after three minutes The eagles greeted each other with loud vocalization and another minute later the male seemed to understand that his partner was receptive and ready for copulation. Most Bald Eagles are monogamous and mate for life and they can live up to 30 years in the wild.

The metadata of my images reveal that it all lasted for about 13 seconds. Afterwards the pair sat together in the light of the setting sun, which is generally interpreted as a sign of strong partnership and a renewal of their bond. I never witnessed this important ritual for a healthy Bald Eagle population and I felt rewarded by watching some essential biology.

Although I had the teleconverter already on the lens I felt it was still a little bit too far away and I cropped the final pictures by about 18% in post process.

NATURE CLICKS #557 - HOODED MERGANSER

Hooded Mergansers, Green Island Wetlands, Iowa

I shoot a lot more than what I ever can publish here in my blog. But today I have a photo from a couple weeks ago that I really still like to share with you. Hooded Mergansers form pairs between November and January and after they migrate here from the south there is only a small time window to take a picture of male and female together. They are monogamous but ones the female starts to incubate, the male abandons her. I try it every year, often with mixed success or no results, to make a photo with both birds together. This time a pair of Hooded Mergansers gave me enough time and finally swam to an area at the pond where the background was not too much illuminated but still enough light to make the mergansers stand out. I never see the males during the summer and just wonder if they immediately move south after their part in the breeding process is done?
