The photographers Roger Deng and Lee Tiah Khee, have now joined up with an armchair birder to publish a scientific paper of the observation in Nature in Singapore. Get a PDF copy of the paper HERE and read the fully illustrated account.
Again and again, bird photographers are contributing to the local knowledge of bird behaviour. These are posted in e-forums, websites and blogs. Now, such observations are being published in scientific journals.
Why publish? Well, once published, the information is freely available.
Kudos to these photographers!
