The Centers for Disease Control and Prevention reports more than 53 million birds across the U.S. have died from highly pathogenic avian influenza. The CDC’s count of 4,000-plus infected is far from reliable. The disease contracting to people is believed to be extremely rare.
More than 1,000 domestic poultry and hundreds of wild birds have died or needed to be euthanized in the state since early spring. Since the first case of a deadly strain of avian flu was detected in Alaska in May, more than 1,000 domestic poultry and hundreds of wild birds have died or needed to be euthanized.
In early October Vancouver Island reached a drought Level 4 which impacted wildlife across the coast. After a mass salmon die off in Bella Bella, concern grew regarding drought and a delayed salmon spawning season. Currently east Vancouver Island is at a drought level of 3, which means adverse impacts are possible, while west Vancouver Island is at a drought level of 2 with less likely impacts. Dave Rolson, Tseshaht First Nation’s fisheries manager, said, “Timing is everything, really, when it comes to fish and when it comes to environmental conditions.”
Biologists struggle to single out a leading cause of the caribou population’s decline. Increased wolf predation, changed migration patterns and climate warming affecting food sources can all influence the herd. “It’s going to be another rough winter again this year without caribou,” Selawik resident Norma Ballot said.
One pod showed up in January and was videotaped fatally attacking two resident bottle-nosed dolphins. They may have also killed a gray whale calf, although a body was never found. Predatory orcas have breached a gray whale safe space in Baja California. Could this spell disaster for a species already struggling for survival?
A backyard chicken flock in Wake County has tested positive for High Path Avian Influenza (HPAI). The positive sample was identified by the N.C. Department of Agriculture and Consumer Services Veterinary Diagnostic Lab in Raleigh.
A third deer in North Carolina has tested positive for Chronic Wasting Disease (CWD). Officials with the N.C. Wildlife Resources Commission reported the deer was hunter-harvested in Surry County this archery season approximately 10 miles from the two previous positive detections in Yadkin County.
Record-setting drought conditions have left many of B.C’s streams and waterways too low for salmon to swim up to spawn. Heiltsuk First Nation leaders say hundreds of fish were found rotting in a creek in Bella Bella, B.C., usually teeming by fall with migrating pink and chum salmon.
Die-offs of krill are in some cases associated with hypoxia (low oxygen) excess sediment suspended in the water column and changes in water temperature. There were recent reports of high levels of Alexandrium in water samples in the areas, and Norton Sound Health Corporation is performing some testing of krill samples (see below). There was also an unprecedented storm event only a week ago, unusual for the storm surge and early season.
Ali Ralson was riding her 4 Wheeler towards Cape Blossom and came upon a beach full of fish. It appears that most of the fish are stickleback although there may be other species involved too. This would suggest an environmental issue that would impact multiple fish species rather than a pathogen. One potential cause could be harmful algal toxins.
