[SBB] Juvenile Heron

[Tom Merigan <[[email protected]]>]

At Sunnyvale Water Pollution District where I and many others have seen 
Green Herons--today I photographed this young bird standing alone 
www.pbase.com/merigan/image/45959610 
and  www.pbase.com/mergan/image/45960142 . I think it is maybe a green 
heron because of its stance,location,lack of other nearby similar 
birds,lack of back spots and eye color.  But it also looks a like juvenile 
Black-crowned heron as well. Has anybody else seen this bird a few hundred 
feet from the entrance on the road closest to the plant leading around the 
saltwater pond? Or can those with more knowledge of exact field marks 
distinguishing juvenile Green from juvenile Black-crowned herons help me 
make this call.  He cooperated by posing well for my pics now I need 
help.  Tom Merigan
