I began #RDAPlenary27 at the #Oval yesterday with a series of pre-meeting events that included an evening reception. In the next couple of days, I'll be giving a short talk in the Software Source Code Interest Group session and helping with the #FAIR4ML session.

I found the Yellow-crowned Night Heron today, after help from the people who wanted to talk about free bible courses and were sitting near the tree it was in. #Birds #BirdPhotography

After the World Cup, I tried to find a juvenile Yellow-crowned Night Heron that's been seen in a local park in Champaign, but failed, only finding a Great Blue Heron and a Green Heron #Birds #BirdPhotography

Things photographed in early June in Singapore: Sunda Colugo aka Malayan Flying Lemur (but it glides rather than flies and isn't a lemur). This is the strangest creature I saw in #Singapore Wikipedia says it can glide over a distance of 100 m with a loss of fewer than 10 m in elevation. (47/47)
