Even before I saw him I felt the shove of his huge wings. There was a sound of air mov­ing. I turned and there he was, his zep­pelin bulk ris­ing inex­plic­a­bly into the air, his long legs dan­gling behind like moor­ing lines. The great blue heron, Ardea hero­dias.

The heron lift­ed from the cat­tails into the cold clear air of Novem­ber with a small bright fish in his bill and an aure­ole of black feath­ers about his head. He lift­ed into the air and made a long low cir­cuit of the marsh. I lived for a moment in that big bird’s skin, in that wrap of slate-grey feath­ers, afloat on those huge bed­sheet wings.

The great blue heron is the most wide­spread of North Amer­i­can herons. In south­ern states and along the coasts of Maine and Nova Sco­tia it nests in colonies of hun­dreds. To the ama­teur bird­watch­er in the envi­rons of Boston, the great blue heron is best known as a lone stalk­er of the water­ways and ponds. Few oth­er birds con­vey such majesty and magic.

Still as a statue

John James Audobon drew the great blue heron in Louisiana in 1821. “You might imag­ine what you see to be the stat­ue of a bird” he wrote in his jour­nal, “so motion­less is it. But now he moves; he has tak­en a silent step, and with great care advances; slow­ly does he raise his head from his shoul­der, and now, what a sud­den start! His for­mi­da­ble bill has trans­fixed a perch.”

Big cranky,” “long john,” “poor joe,” the nick­names we have giv­en this bird betray our affec­tion. A cen­tu­ry ago that affec­tion seems to have extend­ed to the table. in his 1867 “Birds of New Eng­land and Adja­cent States,” Mass­a­chu­setts ornithol­o­gist Edward Samuels not­ed that the great blue heron was con­sid­ered by many a palat­able din­ner. As if to test that asser­tion, Samuels unloaded his own shot­gun into a heron nest. He declared the two “squabs” that tum­bled out to have a taste of duck, but with a strong fla­vor that was not pleasant.

Making a comeback

The slaugh­ter of herons for sport, table or millinery brought the great blue heron to its low­est ebb ear­ly in this cen­tu­ry. Now, pro­tect­ed by law and increased pub­lic aware­ness, the bird is mak­ing a comeback.

Richard Forster, of the Mass­a­chu­setts Audubon Soci­ety, believes the birds are now as numer­ous in New Eng­land as at any oth­er his­toric time.

Forster attrib­ut­es the heron’s brighter for­tunes to a reduc­tion in the use of pes­ti­cides and an exten­sion of the bird’s nat­ur­al breed­ing habi­tat. The lat­ter devel­op­ment result­ed from the rein­tro­duc­tion of beavers into west­ern Mass­a­chu­setts in the 1920s. Beaver ponds are ide­al heron­ries. Breed­ing colonies of five to 30 pairs are now com­mon in Berk­shire and Worces­ter counties.

There is a thriv­ing colony of breed­ing herons in West­boro, in an area of man-made inun­da­tion. The avail­abil­i­ty of suit­able nest­ing areas seems to be the only con­straint on the heron’s con­tin­ued recovery.

On Cape Cod the great blue heron is a win­ter res­i­dent. The birds of oth­er areas of New Eng­land move south for the win­ter. Grow­ing colonies of herons to the north, espe­cial­ly along the coasts of Maine and Nova Sco­tia, account for the greater num­ber of migrat­ing birds sight­ed in spring and fall as soli­tary hunters on our local streams and ponds.

Waiting for prey

The great blue heron is most often seen at dawn and dusk, neck curled back, stand­ing on one corn­stalk leg in shal­low water, wait­ing for his prey to come with­in strik­ing dis­tance. His taste is eclec­tic. He feeds upon small fish, sala­man­ders, lizards, snakes, cray­fish, grasshop­pers, drag­on­flies and mice. When star­tled the heron will emit a low-pitched croak, to my ear sim­i­lar to the sound black ice makes on a win­ter pond.

John Bur­roughs, the famous Amer­i­can nat­u­ral­ist of the turn of the cen­tu­ry, wrote this of the heron: “Our blue heron will stand for hours at a time on the mar­gin of some lake or pond, or on the top of some for­est tree near the water, and the eye might eas­i­ly mis­take him for some inan­i­mate object. He has watched among roots and snags and dead tree­tops for so long that he has nat­u­ral­ly come to look like these things.”

Roots and snags and dead tree­tops are exact­ly the images that come to mind when we see this mag­nif­i­cent bird stand­ing alone and still on a local marsh or pond. But when he lifts from the water and ascends the air with the push of his six-foot wingspan, hearts and spir­its rise with him.
