So as mentioned on 27 December, I’ve been getting into using eBird to record my bird sightings as I walk around the neighbourhood. I’ve been recording lists of sightings every day, which is training me to keep an eye and ear out for birds as I walk around.
Up to today, I’d recorded a total of 25 different species of birds. But today as I was out walking Scully I spotted the 26th, and a rather surprising one it was – an Australian pelican! They’re common along various Sydney ocean beaches and coastal strips, but I’m inland on the harbour shore, where they don’t often come. I don’t think I’ve ever seen one on the ground in this area – and in fact today’s was flying overhead. But as soon as I saw it I recognised it and was astonished that a pelican was flying so far from the sea. I watched it circle on a thermal over the harbour shore for a few minutes, wishing it would come closer so I could get a definite ID. After a while it did come close enough that yes, I can confirm with surety that it was a pelican. Cool!
Today I assembled the comics from the photos I took yesterday. It was a marathon effort, taking about six hours of solid work. The next step is writing the annotations, which I’ve made a start on, but will have to finish off another day.
The other thing I wanted to mention today is that I’ve been noticing a few discussion threads on reddit lately about colourblindness or other aspects of colour science. And I’m dismayed by how much misinformation there is and downright incorrect assertions that people make. I would be happy to provide correct explanations of things about colour and human vision, since this is part of my professional expertise, but it feels futile fighting against such a tsunami of misleadingly incorrect text. So it’s a bit depressing. I guess I should just stop reading anything about colour on reddit.
In COVID news, the Sydney outbreak seems to be being held under control, although there are still thousands of people under self-isolation orders. The number of actual new detected infections has been low the past few days, with testing numbers high. So if this continues, it looks like we have avoided an exponential spreading event. Fingers crossed!

Coincidentally, I was just talking to colleagues about making our eLearning courses more accessible to the colorblind. (One of our developers had used red and green color to distinguish between new and already-visited items.)
