- The Snowy Egret tolerates the close proximity of white Little Blue Herons more than that of dark Little Blue Herons. A white Little Blue Heron catches more fish in the company of Snowy Egrets than when alone. This relationship may be one reason why young Little Blue Herons stay white for a year.
- Another advantage of white plumage is that young Little Blue Herons are more readily able to integrate into mixed-species flocks of white herons, thus gaining a measure of protection against predators.

Declining in much of its range in the United States. Because it does not bear long showy plumes in breeding adult plumage, the Little Blue Heron largely escaped serious population declines from feather hunting for the millinery trade. Habitat loss and human-caused changes in local water dynamics are the most serious threats.
