Dusan Brinkhuizen is one of 4 South American birders who recently surpassed the "400 Bird Barrier" and set a new world's record for identifying the most species of birds in one day. The Team identified 431 species in 24 hours. Dusan was my roommate on this adventure. I saw him spending much time sitting in front of his computer, doing data analyses, dictating, pondering, and devising strategies fine-tuned to the minute -- and of course discussing everything with his team members. Sometimes there were disagreements, but Dusan always had a way of diplomatically creating consensus.
