2024 Bird Feeder Summary

 I now have 12 years of data for my bird feeding station.  It is fun to have data to look at and play with.

All species that show up at my bird feeding station, which includes the crab apple tree that holds the feeders and the ground below are recorded.  The system isn't without flaws, as it is somewhat based on how much time I have to look out the window, but hopefully it averages out over time.
