For those not following the 8 words game, I saw a hoopoe in my garden in Derbyshire last Sunday. I know enough about birds; a. to recognise it instantly and b. to know it was rare. The hoopoe is a frequent visitor to Southern England but that is the extreme limit of its normal range. I reported it to the County Bird Recorder of the BTO (British Trust for Ornithology) – he asked me to fill in a ‘rare bird sighting’ form and told me it was the 35th record in Derbyshire and the first for over 2 years. So, what constitutes a ‘sighting’? Primarily it needs to be accepted by the rare birds committee who make a decision whether to accept it. The criteria vary depending on the bird and the spotter. In my case, although I’m an RSPB member, they won’t have heard of me and wouldn’t take my word for it. if we were talking about some odd little brown warbler, unless it was confirmed by someone acknowledged as an expert. However a hoopoe is extremely distinctive and I have multiple very good photos, so in this case confirmation should not be required. Similarly a pragmatic view will be taken as to whether a number of sightings some time apart should be taken as being one or more individual birds. Historically records are based on photos, then before that on birds trapped or shot or reported by acknowledged experts – it can get a bit vague, but they go back to the 18th century.
[NJ] Thanks. It was the last question I was most interested in. What, in the idealised bird-spotting world, is a sighting supposed to represent? I think you are saying that, ideally, one sighting should equal a particular individual bird -- so if two different individuals spot the same bird on two different days (assuming you could tell, somehow), then that would count as one sighting, not two. Is that right?
