FreeLists / birdky / [birdky] western Henderson Co. sloughs

[Charles Crawford <cr4d@xxxxxxxxxxxxx>]

Got up & out early but it didn't help beat the heat & humidity.
Another HHH day: Hazy, Hot, & Humid.

Anyway I did a tour of various sloughs is in western Henderson Co.  
this morning. I hit the Horseshoe Road slough as well as extensions  
of it by driving some farm tracks between corn fields. Also hit  
Powell's Lake/Grassy Pond sloughs (part of the Sloughs WMA). Then on  
to the I guess what I'll call Pond Creek slough (also part of Sloughs  
WMA).

Highlights:

Com. Moorhen 1 - at Pond Creek slough (where I have seen others the  
past few years)
Great Egrets 38 - at various sloughs (they actually outnumbered the  
Great Blue Herons)
Green Heron 1
Mallard family
Wood duck family
Hooded Merganser family

Observation/Question:

When Great Blue Herons are flushed they very often let loose with  
their "brrraaakkk" call. But when I have flushed Great Egrets locally  
they are silent. But when I have birded in Florida and flushed Great  
Egrets they let out a hoarse call. What's the difference in behavior?

(When I say flushed I don't mean I am intentionally making they fly,  
it just happens that way. I don't mean to imply that I am harassing  
the birds to get them to panic.)
