With the arrival of September, migration’s pace will quicken. In late August, I started seeing warblers passing through my yard. In other locations in the region, birders have shared reports of shorebirds and wading birds.

Jonesborough resident Julia Ellis wrote about her own observation of a green heron that took place recently. She had seen a photo of a green heron with one of my recent columns, which helped her identify the bird.

She explained in her email that she saw the heron at along a creek on her Cherokee Road farm. “I was at a loss as to what it was,” Julia wrote. “It showed up several times a few weeks ago very close to dusk. The picture in the newspaper cleared up the mystery for me.”

Although not unusual at this time of year, green herons have been lurking along the linear trail’s waterways in Erwin. The scientific name — Butorides virescens – of this bird comes from a mix of Middle English and Ancient Greek and roughly translates as “greenish bittern.”

The green in the bird’s plumage appears as a dark green cap, as well as a greenish back and wings. Adult birds also have chestnut-colored neck feathers and a line of white feathers along the throat and belly. These herons often assume a hunched position, which can make them look smaller than they actually are.

Keep alert when walking along the trails in Erwin and you may catch sight of one of these interesting herons, too. Farm ponds in the countryside around Jonesborough, as well as wetland habitat around Persimmon Ridge Park, are also good places to look for this small heron. Most green herons will depart in late September and early October. This small heron retreats from the United States during the winter season but will return next spring in April and May.

A few herons — great blue heron and black-crowned night heron — remain in the region throughout the year, even enduring the cold winter months in Northeast Tennessee, Southwest Virginia and Western North Carolina.
