In the afternoon, I went to the dyke again. I didn't saw too many wildlife today, but I did came across the Bald Eagle pair when I was heading home.
The more visible one.

If looks can kill...
Such beautiful birds...
Another point-of-view of the pair. I wonder who's the male/female?
According to this site, there is a book titled "The Bald Eagle" by Mark V. Stalmaster, and in this book there is a formula that helps to determine the sex of the bird.
"Sex = (bill depth x 0.392) + (hallux length x 0.340) -27.694 (measurements in millimeters). If the answer is positive, the eagle is a female. If the answer is negative, the eagle is a male."
Good tip, although I wish it works without catching and handling these powerful raptors.
