If you can't stand the heat stay out of the greenhouse.

More birds. I got 2 more species (Yellow-Billed Cuckoo and Louisiana Waterthrush) today pushing my total to 111 for 2026, now more than my total for 2025! Chased a Wood Thrush for a while but it didn't want to be seen.

I planned on doing an eBird checklist last night. I got 51 species. I didn't plan on going out this morning but I did. I got 45 species including 6 that I didn't get yesterday. I wish I had more time during the spring migration to bird.
