I agree. Bryan's reports are fascinating. Besides the massive numbers of Marbled Godwit and Long-billed Curlew sightings yesterday, I noticed several eBird reports stating "FOS".
Yes, that's one "advantage" of being one of the RBA Compilers - you see whats going on around the state while looking for the rarities. Any volunteers out there??? We are very short-staffed, and if you can help with one week a quarter we would very much appreciate it. Thanks Bryan, your posts are much appreciated.
