Requiem for a Double-crested Cormorant

At Belle Isle yesterday looking for anything of interest, but especially dragonflies.  Found plenty of interest, including an apparently sleeping juvenile double-crested cormorant.  But not that many dragonflies.

Seen perched at the edge of the lake across from the Yacht Club.

I was stepping lightly and it awakened by didn't fly or swim.  Hmmm.

Odd.  Unbalanced with the tip of its tail submerged in the water.

It seemed thirsty.

After that drink it seemed to settle down, but was still wobbly on its perch.  And it bothered me that the tip of its tail was submerged in the water.

Continue on.  Leave it alone.  Maybe it will recover.

Thirty minutes later when I returned it was dead and its tail was more deeply submerged in the water.

I felt bad.  Was it Avian flu?  West Nile virus?  Lead or mercury poisoning from fish in the river or this lake?  I stopped for a bit to decide what to do.  I wanted to collect the bird for the University of Michigan bird collection; however,  ever since Janet H. left that division seems so out of touch and discombobulated.   They don't answer their phone or emails and they don't respond to messages left on their voicemail.  

Its position on the perch made it appear peaceful.  I don't know how long it will remain this way.  I was too busy to return today to check on it.  I might try tomorrow.

Update:  I didn't get to return for several days or so and the bird was no longer present on the perch.
