BPP in the literature

It’s very gratifying to read this acknowledgement:

The authors are indebted to the original BPP [Bird Phenology Program] observers and coordinators who collected the extensive data that comprise the BPP and were used here…. Thank you also to the BPP participants from around the globe who have worked to revive those records by digitizing and transcribing them in recent years.

The paper: “Long-Term Trends In Avian Migration Timing For the State of New York,” by Jessica Zelt, Robert L. Deleon, Ali Arab, Kevin Laurent, and Joel W. Snodgrass.

I haven’t transcribed cards for a while; it’s time to get back to it.
