I spent less than two hours and had 16 warbler species, low and lovely, along the Magee Marsh boardwalk! Close enough for cell phone pics!

Migration is highly variable, and you never know what birds we'll see from year-to-year. We found 243 species in 10 days, including three notable rarities! The reasons for that are 1) birding here is aMAYzing!; and 2) our guides are SUPER AMAZING! #BirdsRule #BiggestWeek2023
