DEC 10: A two (or three?) eagle morning [BLOG]

This is a draft of my current blog-- the first part will tell about the loss of Joy and the new female.

The cold front had worked its magic. The last two days of heavy clouds, intermittent showers and increasing winds had made it unwise for us to venture very far out into the wetlands next to our home. This morning we were out about 10 minutes before dawn. The sky was already blue, with the light reflecting white off the scattered cirrus clouds and a waning moon. shining brightly.

The temperature had dropped to the high 40s (~9 degrees C) and the northwest wind was barely perceptible. By Illinois standards it was shirt-sleeve weather. A light jacket sufficed for me, but Mary Lou was layered in fleece and had her hands in her jacket pockets as we walked the gravel road. She always says that she was born in December and hasn't thawed out yet! As usual, Mary Lou's faster pace moved her several yards ahead of me. At 6:55 AM, one minute before sunrise, a Bald Eagle suddenly flew low almost directly over her head. I quickly raised my camera and immediately learned that I had forgotten to turn it on! By the time it was operational the eagle had almost disappeared behind the trees. All but one of my series of shots missed the mark, but a single clipped-wing image provided evidence that it was an early fifth year bird, almost certainly the new companion of the male who lost his mate about a month previously. Their nest is about 1 1/2 miles to the NW of this location.

By the time we reached the Harbour Lake water conservation area we were still shrouded in shadows but the sun had reached the treetops across the lake.

In the distance, I nearly ignored a large bird flying eastward, thinking it to be a heron. To be sure I used my camera as a spotting scope and saw that it was an eagle. I was able to snap only two shots before it disappeared behind a grove of trees. Using Google Earth, my best approximation of its range was 0.45 miles (730 meters), so the photo had poor resolution. Back home, the view on the computer screen revealed it to be an adult Bald Eagle with one leg dangling down. This photo was taken at 07:19:57 and is cropped and sharpened:

This next photo is stamped two seconds later. With this one I modified the color temperature and increased the dynamic range as well as strengthened the sharpening in an effort to better visualize the eagle's legs:

I walked to the north, closer to where the eagle had disappeared, but only two minutes later (at 07:22:39 AM) the same adult eagle with a dangling leg once again flew into view, this time flying to the WSW, at a range of approximately 0.19 mile (303 meters). The time stamp for this photo is 07:22:59 AM):

This is the sharpest of a burst of photos I took as the eagle flew away from my position (time stamp 07:23:01 heavily cropped). It shows that the right leg is the one hanging down.  The eagle disappeared into the distance, flying WSW towards the Everglades.

 I wandered northward to the wet prairie, where I captured a delightful view of a Great Egret foraging in the slough:

...and settled on a snag at the northern end of the prairie:

While I was enjoying the herons an Osprey flew by and oddly seemed more intent on what was behind him than looking where he was going:

I looked there as well and to my utmost surprise saw two large dark birds in a dead melaleuca tree about 0.2 mile (320 meters) away. They had flown in while I was busy with the heron, and were adult Bald Eagles! The one on the right was noticeably larger, a female:

The eagles were at least 0.2 miles (320 meters) distant, and the shadows of the branches partially obscured their features. I was particularly interested in determining whether the female was the new companion of our resident male, but this photo seems to show the tail of an adult bird:

...revealed none of the distinctive dark marks shown by the younger female. Here is a photo of the new female's tail that I took this past week:

The original female (named "Joy") was last documented at the nest on October 30. On November 7th an apparent female roosted near the nest as darkness set in, but the image showed her right leg hanging down with the talons possibly distorted. Although the reason for the original female's disappearance is unknown, it is possible that she had suffered an injury. Earlier this year the nest observers noted that she often dangled one of her legs. I captured this image of her on January 11, 2014:

So, the mystery deepens. Were my photos simply not sharp enough to determine the age of this female that was with the male today? Is Joy still alive and in the area of the nest? Is it possible that the new female drove her away?

Ken , Great pictures .. It is very possible that Joy did get hurt and the new Female made her Leave . I have seen the same thing happen in another Eagle Nest . The Females Talon was hurt really bad and it fell off and the Male take care of her and out of no were a new female come in and took over . If Joy talon is hurt she can't fight back and Pride will move on .
