Half a continent away from its natural habitat, an American Black Vulture recently visited Fort Resolution.
Residents on social media this week, remarking on the unusual sighting and sharing pictures of the animal perched and in flight. The bird, known for its dark plumage and black, featherless head, is typically a southern species, concentrated around Mexico, parts of Arizona, Eastern Texas and the East Coast. ItSA国际影视传媒檚 rarely spotted in the Midwest or West Coast.
The rare sight caught birder Gary Vizniowski's attention.
He joked that travelling the 155 km from Hay River to Fort Resolution would SA国际影视传媒減rove that (he) was a true 'birder'. He did SA国际影视传媒 though it some time to find the animal, he told News/North over email. Asking around town, he received hints that it was hanging around the dump, where he discovered a SA国际影视传媒渓arge bird in the trees surrounded by ravens.SA国际影视传媒 Binoculars revealed it was a vulture.
The bird flew away and only returned when Vizniowski was watching some gulls. He caught the vulture in mid-flight with his camera.
SA国际影视传媒淣ot sure what brought it up here as it is thousands of kilometres out of its normal range,SA国际影视传媒 he wrote.
Weighing in, Ornithologist Robert Bromley confirmed the bird was an American Black Vulture that was SA国际影视传媒渨ay, way out of its range.SA国际影视传媒
Vultures take advantage of the wind, Bromley said, which can sometimes lead to sightings outside of bounds in locations like Ontario. NWT, however, is a rare case.
Aside from the unusual sighting Bromley said turkey vultures have previously been spotted, including notable reports in Yellowknife, Fort Reliance in the early 1990s, and a possible one in the Mackenzie Delta.
The rare occurrence of a Black American Vulture north of 60 could be attributed to a changing climate, he said.
SA国际影视传媒淲ith climate change, thereSA国际影视传媒檚 so much energy in the atmosphere, the winds are doing crazy things,SA国际影视传媒 he said.
As the atmosphere warms, it has more energy. That results in more unusual or extreme climate events. Windier, stormier, and more unexpected weather patterns are more likely to throw the birds off course.
SA国际影视传媒淭hat really influences this particular bird because itSA国际影视传媒檚 so efficient at getting places without putting out much effort," he said. "It just takes advantage of moving air.SA国际影视传媒
SA国际影视传媒淚t could be it just got caught up,SA国际影视传媒 he said, explaining a jetstream looping up and down meant it was very possible the bird was caught in a weather system.
On top of being a long way from home, the bird may face additional challenges in the territory.
Vultures typically hunt by smellSA国际影视传媒 except for the American Black Vulture, which depends on other birds like turkey vultures to lead it to sustenance. Turkey vultures also often hunt alone, whereas Black Vultures work in groups as they scavenge and eat carrion.
ThatSA国际影视传媒檚 another reason the sighting is so odd: The bird spotted in Fort Resolution was alone. That said, any bird out of normal range SA国际影视传媒 one caught in a strange habitat, and unfamiliar with local predators and efficient food gathering SA国际影视传媒 is at risk, he said.
SA国际影视传媒淲hat (this bird) has got going for is it is efficient at migrating long distances simply by soaring,SA国际影视传媒 he said. SA国际影视传媒淚f it decides to move, it can.SA国际影视传媒
He emphasized that climate change has affected the distribution of bird species and weather events have increasingly thrown the animals into unusual settings.
SA国际影视传媒淲eSA国际影视传媒檙e seeing more unusual sightings generally, and across North America, for sure,SA国际影视传媒 he said.
SA国际影视传媒淎s the environment changes, itSA国际影视传媒檚 important for us to stay plugged in on what those changes are. For things like birds itSA国际影视传媒檚 also enjoyable and fun to - when you see something like this - find out more about it and read up on the species.SA国际影视传媒
However, itSA国际影视传媒檚 important to ask SA国际影视传媒渨hat that means,SA国际影视传媒 he said.
