General information about herons and egrets in the Houston Area
There are many kinds of herons and egrets in the Houston area. The most common species admitted to the HHS Wildlife Center is yellow-crowned night herons (Nyctanassa violacea). Despite being called night herons, these birds will forage during both the day and night time. Yellow-crowned night herons have been around for a long time, and show up in the fossil record dating back 2-2.5 million years ago. The oldest was banded in Mexico and lived to be over 6 years old. Some other species in the area are great egrets (Ardea alba), cattle egrets (Bubulcus ibis), reddish egrets (Egretta rufescens), little blue herons (Egretta caerulea), great blue herons (Ardea herodias), green herons (Butorides virescens), and black-crowned night herons (Nycticorax nycticorax). These birds are related to other wetland species like the roseate spoonbill (Platalea ajaja) and ibises. Most aquatic birds breed during the spring and summer months. They can be found in huge rookeries most commonly in April.
