Fascinating story. The story about the Dusky Woodswallow is also a good one.
On a slightly related note, have there been many birding hoaxes wherever you guys are (UK, UZ, NZ, continental Europe etc)?
Earlier this year, there was a 'birding scandal' that rocked the Victorian (Australian) birding community, involving a relatively young birder who did a 'Vic Twitch' in 2014 to set a new 'big Victorian year' record. He had support from some of the best birders in Australia re: advice on where to find specific species, assistance with identifying tricky species, and swift notifications when rarerities were reported. At the end of 2014, the birder had seen 401 species in Victoria, beating the previous record of 392 set in 2010 by a birding duo.
He became a minor celebrity in the birding world, giving talks about birds to school kids, and perhaps being interviewed on the radio (I think). His blog received thousands of hits from around the world as birders followed his adventures; Victorian birders were willing him on to break the record and were genuinely elated when he broke it and set a new 400+ record.
The only problem was, he faked some of the sightings that he supposedly made on his lonesome. Around Easter this year he wrote a long post on the Victorian Birders Facebook Group admitting to a few hoaxes - including a House Crow sighting in downtown Melbourne that wasted the resources of various government departments that tried to capture the bird (re: it being a destructive invasive species). A photo of a frigatebird supposedly taken in Victoria weeks after the initial report turned out to be a photo he took in Fiji. Another photo of a sandpiper I believe, was taken of the web. It is believed that he set up fake accounts to verify sightings.
He retracted his claim on the record and it is still unclear how many sightings were faked. He wrote about having psychological problems, issues at university, stress etc and how he thought the problems would go away by breaking the record blah blah blah. Birders were initially supportive, but then angry - many wasted resources (time, petrol, accommodation etc) chasing birds that never existed. He was then expelled from a few Facebook groups (including one he founded!) and banned for life from posting rare bird sightings to the local 'bird line'. It was a cautionary tale to many Victorian birders who were either chasing a record, or chasing birds based on supposed sightings.
Have there been any bird hoaxes in your neck of the woods?
