Beaver 1967 Hudsonian Curlew 11 July 1400 Barrow Alaska Near AACs building. Dr. Patella, Tom Custer and I were driving south forwards lines I and II (Lemming traps line) when Dr. Patella sighted 3 large shore birds sitting on Beach ridge about 50 yds East of us. He identified them as Hudsonian Curlews. I took several photos with the 350mm lens, and then attempted to get close enough to collect one. As I prepared to do this, one bird began to do a strange walking in circles and sort squatting and displaying its head and extending the wings. It did this several times and then the next bird did the same thing. I then approached but they flew off. I took a long shot with #9? but no sense.
