Free Manhattan Bird calendar for 2025: https://www.cs.columbia.edu/~smb/doc/manhattan_bird_calendar_2025.pdf. All pictures were taken by me in Manhattan during 2024. It's Creative Commons-licensed as attribution, no commercial use, share-alike. But good printing and binding may not be cheap—printing a copy two-sided, in color, with decent paper and spiral binding, at Staples, cost me about US$30. (I'm going to update my software to permit cheaper, including at-home, printing options, and I'll eventually open-source the code.)

Enjoy!
