[wisb] Re: Vernon Marsh - Mukwonago

This is a cooperative feeding behavior. They all drop their heads under at the 
same time and surround and corral the fish. I have seen underwater video of 
this. Pretty amazing.

Subject: [wisb] Vernon Marsh - Mukwonago

Thursday afternoon, I decided to stop by Vernon Marsh near Mukwonago to see 
whether there were many birds to enjoy.  I entered the area off County Hwy NN, 
just west of the RR tracks. 

I was delighted to see dozens of American White Pelicans, and small quantities 
of Great Egrets, Sandhill Cranes, and Great Blue Herons.  There is also a lone 
Tundra Swan (I beleive) in the same area I saw it late in the spring. 

All of the aforementioned birs were at the south end of the area, on the west 
side of the trail that crosses the marsh from north to south.  From the Norht 
end off Frog Alley, it would be a long walk to the other side.  From the south 
off Ct Hwy NN, it is about a 3/4 mile walk on a easily assessible trail albiet 
the bugs were a tad annoying.  Small price to pay :-)

After watching the Pelicans, it was interesting to watch them.  For a brief 
period, they would all bob around and drop their hesads into the water nearly 
in unison.  Anybody know what that behavior is?  I'll try to post a brief video 
of this a bit later. 

Also, if I recall from an earlier posting, these are young Pelicans since they 
lack the "bulb" on their bills and many had light gray plummage. 

Lastly, I noticed that some of the Pelicans have a blue band, whereas others 
appear unbanded altogether. 

Here are links to some photos.  They are a bit hazy and I was shooting toward 
the sun so the colors are a bit dull since I'm taking photos on their "shady" 
side.
