Bird Flu Returns to Town with Fall Migration it’s just wings?



it's just wings


The Raptor Center at the University of Minnesota was prepared to handle an influx of sick it’s just wings after a highly contagious strain of Avian Influenza began spreading across the United States.

“it’s just wings But we could never have anticipated the flood patients that arrived,” Dr. Victoria Hall, the executive director of the center which provides medical care to birds of prey, said.


From March through June, Dr. Hall and her associates saw over 180 flu-afflicted birds. This included scores of red-tailed Hawks, great horned Owls, and bald Eagles.  Many of these birds were either severely ill or incapable of standing or seeing due to seizures. The care of these animals, only one of whom survived, was emotionally draining and required long hours with personal protective equipment such as Tyvek suits or respirators.

It was it’s just wings a relief to find that cases dropped off this summer, with only one in July and zero in August.

The sick raptors were back in September. The center had 11 confirmed cases last month of avian influenza. Dr. Hall stated that it was “definitely coming back through.”

The avian flu epidemic this year is the worst since 2015. 2015 was the last time that the United States was struck by bird flu. The virus has already infected 47 million birds that are part of the United States domestic flocks, almost the same as the 2014-15 season.


Bryan Richards, the emerging disease coordinator at U.S. Geological Survey’s National Wildlife Health Center, said that this year’s epidemic is “radically different” from previous years.

According to Mr. Richards, this year’s spread is wider, reaching almost all states and affecting more wild birds than ever before. In fact, it has infected more than 100 species across North America. Experts say the virus poses no risk to humans at this time.

The virus didn’t die out like in 2015 and did not disappear over the summer. It continued to circulate among wild birds, many of whom spend their summers in the Arctic.

As wild birds migrate south for winter, the virus is carried by them. The number of cases is increasing in many northern states, and the virus is also appearing for the first time in some southern states, including New Mexico, Arkansas, and Mississippi.

An Uneven Crisis: A study shows that the risk of extinction is not evenly distributed across the avian species. The most unique birds will likely disappear first.

Hammering Away: A study has shown that woodpeckers don’t absorb shocks when they peck, and likely aren’t being concussed.

Although poultry farms are well-acquainted with the dangers of avian flu, this new threat is very real for many zoos and rehabilitation centers that house wild birds. They are preparing for a resurgence and wondering if the virus will be around.

“We’ll just need to be on alert,” Dr. Trevor Zachariah, director of veterinary programs for Florida’s Brevard Zoological Society, said. Infected wild vultures continue to find their way onto the property. “We might have to accept this.”

Spring surge

Avian influenza flies its way across the globe in the bodies and feathers of migrating birds, particularly in birds like ducks, geese, and gulls. These birds can be carriers of the virus but not show’s just wings They share summer habitats in the Arctic where they might swap pathogens and pick up new flu strains.Spring surge

Dr. Keith Poulsen is the director of the Wisconsin Veterinary Diagnostic Laboratory. He said, “It’s almost like bringing your kids to daycare from different areas.” “As they mix, that’s where virus movement takes place on a global level.”

Flu-infected birds move, and the virus is released in their feces, saliva, and mucus. This results in infection in farmed fowl flocks, which can lead to fatal flu outbreaks.


Eurasian H5N1 flu, a highly pathogenic strain of flu, was discovered in birds in Eastern Canada in the latter part of 2021. The virus spread down the Atlantic coast from Florida to Florida, and then it exploded this spring when migrating birds brought the disease north and west.

It infiltrated commercial flocks hundreds upon hundreds and began to fall wild birds, causing the death of entire families of owls.

Ashton Kluttz (executive director, of Bird Rescue Center in Sonoma County), Calif. said, “We’ve never witnessed anything like this before.” He also created additional makeshift hospitals to accommodate the patient load.

(The virus was also discovered in mammals from foxes and seals.


Scientists don’t know why this virus is affecting so many wild birds. The virus may have evolved to be more infectious to wild birds or to be better adapted to them. Dr. Poulsen suggested that the virus might have been more likely to spread in wild populations if there was a cold and wet spring.

The sanctuaries, rehabilitation centers, and zoos scrambled for new safeguards, moving birds into their facilities and suspending public programs. Tri-State Bird Rescue & Research in Delaware identified its first case in February, it’s just wings triggering a three-week quarantine. It adopted new disinfection protocols, and it stopped accepting waterfowl from any other rehabilitation centers.

Lisa Smith, executive director of the rescue, stated that there has been no outbreak at their center. She added that the virus was still present.

Although there were many cases this summer, the virus did not completely disappear. It’s back.


Blue-winged teal is a type of duck and one of the first birds to migrate south in the autumn. Three Mississippi-based hunters harvested teal were found to be positive for the virus, making it the first time the virus was detected in the state. Mr. Richards stated that the finding confirms that the virus was present in northern latitudes throughout the summer. “And it’s returning on the wings wild waterfowl.”

Dr. Poulsen explained that Wisconsin saw a rise in wild bird diseases around Labor Day. He also recently reported its first outbreaks of poultry disease since it’s just wings May. He said, “We really hoped that we were out of the woods.”

It appears that the virus is making a comeback in northern regions such as Canada, Minnesota, North Dakota, and Alberta. Experts have stated that the virus’s surge in recent months has been less than the one seen in spring. Margo Pybus, a specialist in wildlife diseases at Alberta’s Fish and Wildlife Division, said that “but there are lots more geese and birds to come down from the Arctic.”

Wildlife facilities further south are ready for fall migrants. Southern California was spared during spring, but Dr. Hendrik Nllens, vice president of wildlife health at San Diego Zoo Wildlife Alliance does not believe that this fall will be any different.


San Diego Zoo Safari Park and San Diego Zoo Zoo covered their outdoor aviaries. They also removed food and water sources that could attract avian intruders. it’s just wings  Dr. Nollens stated that they also relocated 900 birds to more protected habitats. This was a “herculean effort” that included hundreds of flamingo relocations.

Employees guided the flamingos to enclosed trailers that transported them to indoor or covered habitats. These new areas were modified by staff to accommodate the leggy-wading birds. They added feeding pools, trimmed low-hanging branches, and raised the sprinklers to ensure their feathers were in good condition.

It is not clear when the flamingos are going to return home. Dr. Nollens stated that “When do you stop doing these kinds is actually a difficult challenge.” “We don’t know what’s going to happen.”

The long-term

The outbreaks in Europe began earlier than those in North America. However, the signs were not encouraging. According to the European Center for Disease Prevention and Control, the virus has survived multiple migration cycles and is now causing “it’s just wings the greatest avian influenza epidemic” on the continent.


Scientists said they expect the virus to spread northward in the spring, despite it being difficult to predict the future. Richards stated that there is no reason to believe the virus will disappear soon.

What happens if the virus persists? Dr. Hall stated that the virus could have devastating consequences for anyone who has permanently captive or transitory wildlife.

She said that the Raptor Center will continue to test all patients for the virus and is looking into building a permanent triage area and quarantine. California’s Bird Rescue Center has recently added an avian influenza unit in its new facility. However, it is not expected to open until late 2023.

Oregon ZooOregon Zoo moved many of its birds indoors last August and does not want the animals to be kept in a cage for too long. “It’s not good welfare,” Dr. Carlos Sanchez, head veterinarian at the zoo, stated. They need space to move. They need sunlight.” Employees are working to reopen the aviaries with new precautions, including foot baths for visitors to disinfect their shoes.

Long-term management of the risks will require the ability to be alert and flexible, tightening or loosening precautions when outbreaks occur and fade.


For instance, at the Pittsburgh Zoo & PPG Aquarium employees will wear full P.P.E. if the virus is detected in the surrounding area, according to Dr. Justin Rosenberg.

Dr. Rosenberg recognized that there is a certain “preparedness fatigue” after the spring surge and more than two years’ worth of coronavirus-related precautions.

The zoo is determined to protect its avian friends, which include flamingos and ostriches. Dr. Rosenberg stated that the 3-year-old duck, who has “one of my favorite names,” was also at the zoo. “We will do everything we can to keep Ritz Quacker safe.”
