Meet the Nice Blue Herons of Richmond, Virginia


Every spring on the James River, a Chesapeake Bay tributary that runs via downtown Richmond, Virginia, Nice Blue Herons interact in mating dances at rookeries simply west and east of city. The heronries are doubtless remnants of a former rookery generally known as Pipeline Rapids.

The putting waterbird is a fixture in ponds, wetlands, coasts, and related habitats from southern Alaska to northern South America. It could quantity as many as 5 million people, based on the Worldwide Union for Conservation of Nature.

At one time, nevertheless, it struggled like many different chook species within the mid-1900s. In response to researchers on the Heart for Conservation Biology (CCB) on the School of William & Mary in Williamsburg, Virginia, Nice Blue Heron populations within the Chesapeake Bay area reached a low of 1 dozen recognized breeding colonies within the late Sixties, a results of the results of DDT. 

A half-century or so later, in 2013, a CCB survey of the birds documented 14,126 pairs in 407 breeding colonies within the Chesapeake; the species had develop into probably the most widespread and plentiful breeding waterbird within the bay. On the time, Nice Blue Heron rookeries alongside the James River close to Richmond every hosted between 35 and 75 pairs. CCB is planning one other survey of the Chesapeake’s waterbird species in 2023; the survey could embrace Nice Blue Herons.

A decade in the past, the biologists additionally discovered that some giant Nice Blue colonies that have been secure for many years had began to splinter. Bald Eagles even have been recovering from DDT for many years, and so they typically declare locations to nest in heron rookeries.

What herons eat

Nice Blues are widespread on the shores of open waters and in wetlands throughout most of North and Central America, in addition to the West Indies and the Galápagos Islands. The species is the biggest North American heron. Its main meals is fish, though it opportunistically feeds on shrimp, crabs, aquatic bugs, amphibians, reptiles, and smaller birds. Herons find their meals by sight and swallow it entire.

Nice Blues normally dine solo, however on this run of the James River, dozens are sometimes in view, standing on rocks within the river or wading in swimming pools and riffles.

How herons nest

The birds construct cumbersome stick nests, and females lay three to 6 pale blue eggs. Pairs elevate one brood annually. Each mother and father feed the younger by regurgitating meals; adults devour 4 occasions as a lot when feeding chicks. The eggs are incubated for 28 days, and the nestlings fledge about 60 days later. Younger birds are on their very own by the center of June. 

On the James, Nice Blues, together with Ospreys and Bald Eagles, feast on American shad within the river’s rapids. The herons stalk the shallows, their gray-blue feathers backlit within the morning solar.

The Richmond Nice Blues have the very best feeding spots on the river, native residents say. When shad splash their manner upstream in spring, the herons can virtually fall out of their nests to fish. Statue-still, the birds peer beneath the floor. All of a sudden, their lengthy necks jut ahead to spear the catch of the day. A piscine flash of silver, and the meal is gone, sliding down a heron’s lengthy throat.

Richmond’s Nice Blues reside the nice life, for now. American shad are in decline alongside the James and all through the Chesapeake Bay area. Shad abundance ranges, based on the James River Affiliation, a conservation group, have reached an all-time low. Bringing again the fish will take defending the river’s water high quality and habitat, and addressing water withdrawal results, predation by invasive species, and boundaries to fish passage resembling dams.

Whither go the shad, so, too, the Osprey, Bald Eagle, and Nice Blue Heron.
