The black crowned night heron, nycticorax nycticorax, is migratory over much of its range, with the exception of birds in the deep south. Mainly migrates because extreme cold drives fish to deeper waters, making it difficult for the heron to find prey.

There are many different species of Herons. I didn't find any of them listed on the Endangered Species List (US Fish and WildLife Services). Some specific species are listed by individual states as threatened or endangered. As to the general populations of all Herons facing extinction, I can find no evidence to support such a statement. The White-Bellied Heron, and the White-Eared Night Heron, are listed as endangerd, but I found no forecast for their extinction.
