  • Lemongello, Steven. "Professional birder, author, got start in Cape May Point", The Press of Atlantic City, October 24, 2009. Accessed September 12, 2019. "Like a migrating bird returning to its nesting grounds, noted birding guide author David Allen Sibley has returned to the town where he first learned about birdwatching.... The writer, now based out of Concord, Mass., first came to Cape May Point in the fall of 1980, 'when I essentially dropped out of college to go birdwatching full time.'"
