It was fast asleep, out in the open, in only 18 feet of water. I've never seen one asleep out of its den and so shallow before.22 Sep 2025 15:16 +0000at://did:plc:eahppc2gwvq43pbtrpgm2h4j/app.bsky.feed.post/3lzgpalg5sk23https://bsky.app/profile/ericlippert.com/post/3lzfa4xbrpk26I spent the morning diving in the Hood Canal and got a pretty decent shot of this beautiful golden dirona. Biggest one I've ever seen, at least as big as my palm.22 Sep 2025 01:13 +0000at://did:plc:eahppc2gwvq43pbtrpgm2h4j/app.bsky.feed.post/3lzfa4xbrpk26https://bsky.app/profile/ericlippert.com/post/3lyq3lnfc5c2tI got a shot of the great horned owl that lives at my friend Amber's place. It was hooting at the owl that lives next door when we interrupted it, which probably accounts for the withering look. 🪶13 Sep 2025 15:25 +0000at://did:plc:eahppc2gwvq43pbtrpgm2h4j/app.bsky.feed.post/3lyq3lnfc5c2thttps://bsky.app/profile/ericlippert.com/post/3lxaf3wjxpc2yA couple recent shots of a cormorant on a riverbank, just before and just after taking flight. 🪶25 Aug 2025 16:08 +0000at://did:plc:eahppc2gwvq43pbtrpgm2h4j/app.bsky.feed.post/3lxaf3wjxpc2yhttps://bsky.app/profile/ericlippert.com/post/3lx6epqyun22qHere's a cute little sandpiper I saw hunting for breakfast at sunrise on a river bank a couple of weeks ago.24 Aug 2025 20:56 +0000at://did:plc:eahppc2gwvq43pbtrpgm2h4j/app.bsky.feed.post/3lx6epqyun22qhttps://bsky.app/profile/ericlippert.com/post/3lwmwqysbhc2sI was just going for a little walk at Shilshole Bay, said to my wife "I'm going to grab the camera in case there's an eagle" and literally 30 seconds later, an eagle was fighting with an osprey over a fish directly above me.17 Aug 2025 22:31 +0000at://did:plc:eahppc2gwvq43pbtrpgm2h4j/app.bsky.feed.post/3lwmwqysbhc2shttps://bsky.app/profile/ericlippert.com/post/3lu6zobpd2s2mI was just out for a walk in Carkeek Park (bring shoes you don't mind getting wet, the stream is overflowing onto the path by the beaver dams) with @thursdayrome.bsky.social; she spotted a brown creeper.
