Bird update March 2023
Click to enlarge I’m still birding voraciously. I’m up to 89 species in my county for the year. So that means I added a dozen since last month. A few of those are freshly-arrived migrants from southerly climes, and some are just me putting in the time to go rack up waterfowl at nearby lakes. I’ve maintained my high county ranking, which has oscillated between #4 and #2 this month. …

Yard list 2021
It hasn’t been a good year for much, but I did get a lot of birding in.

Friday fold: Home décor
Busy weeks lately; apologies for the minimal bloggery, friends. For this week’s Friday fold, I offer you a view of some of the outdoor decorations at our new house: In the lower basket there is a cut and polished block of Castile Formation rock gypsum + limestone, showing varves that have been folded, apparently by hydration/dehydration volume changes of the gypsum/anyhdrite laminae: This is from the State Line outcrop on …
