BirdData: some problems?

Not really. Even by taking in of the whole 111Km x 111Km square, there is no way that some of the species could be sighted there. Obviously, there are well meaning, but ornithologically deficient people out there who post to BirdData, sightings that are furphys. Pity, because the database is used for researchers, and junk data gives junk results, as we know from the first law of computing, GIGO.

I am going to have to start looking a bit harder around my patch, as I have obviously been missing a few cracking birds. Some I have missed are; Red Junglefowl, Cotton Pygmy Goose, Baudin’s Black Cockatoo, and Common Greenfinch, to name a few. Has anyone else on the list looked up their postcode in BirdData to see if there are any “ghost” species lurking? >> >> Carl Clifford >> >> >>
