Cool Facts

The white form of the Great Blue Heron, known as the "great white heron," is found nearly exclusively in shallow marine waters along the coast of very southern Florida, the Yucatan Peninsula, and in the Caribbean. Where the dark and white forms overlap in Florida, intermediate birds known as "Wurdemann's herons" can be found. They have the bodies of a Great Blue Heron, but the white head and neck of the great white heron.


Although the Great Blue Heron eats primarily fish, it is adaptable and willing to eat other animals as well. Several studies have found that voles (mice) were a very important part of the diet, making up nearly half of what was fed to nestlings in Idaho. Occasionally a heron will choke to death trying to eat a fish that is too large to swallow.


Great Blue Herons congregate at fish hatcheries, creating potential problems for the fish farmers. A study found that herons ate mostly diseased fish that would have died shortly anyway. Sick fish spent more time near the surface of the water where they were more vulnerable to the herons.

Sorry for the quality. I know (overexposed areas, a little soft ...). But, the conditions are very hard (distance about 100m, the birds are very fearful and permanently change his locations, at the end they fly away!). But is for the first time i have see those beautiful creatures in freedom and more than 4 simultaneously!

I don't understand how some of you can makes the portraits of those birds (maybe only in the zoo)?
This shot was taken at 650mm focal length and they are so far, but when i attempt to come closely, they fly away! Anyway of your attitude about this shot, i am happy with this experience. It's so fascinating to sneak up closer and closer and take shots at differents f/stops, exposure times ...

Hi Sochirca, nice capture to get all these together. I think you have pointed out the only nits that I can see, so well done.

Nice composition, a bit closer could have been better. Getting portraits is just a matter of luck, sometimes you can get really close to them...
Well done.
TFS.
