I saw 16 Little Blue Herons at Black Marsh - aka North Point State Park (se 
Baltimore County) on 09/05.
Specifically, take the east path near the pay gate until you come to the 
wetlands on the left hand side.

15 were first year birds; of those 14 were all white and one had splotchy gray 
on its white body.
There was also one adult bird. All young birds had pale gray bills and light 
yellow-green legs.

All the birds were located fairly close together, and it looks like a breeding 
colony occurred at the park. 5 of the birds were in a tree for a while.  I did 
not see any nests. Are there any previous records of breeding Little Blue Herons 
in Baltimore County? The Yellow Book says not.

Incidentally, I did see one Adult Little Blue Heron on May 16 at the park. the 
heavy snows last winter cleared away a great deal of the vegetation from the 
wetlands -- making the habitat more favorable for herons.  



                          Good Birding!
