Kōlea (Pacific Golden Plovers) are back in Hawaiʻi! They breed in Alaska over the summer and return to Hawaiʻi in the fall, usually to the exact same location. They make the non-stop flight from Alaska to Hawaiʻi (4800 km) in 3-4 days.

I was lucky enough to get some video of a Hawaiian Green Sea Turtle at lunchtime yesterday. I’ve posted longer videos on YouTube. Link in first comment
