Náttúrufræðingurinn 18 Þakkir Jóhann Óli Hilmarsson, Gunnlaugur Þráinsson, Ib Petersen, Hermann Bárðar- son, Ólafur Einarsson, Einar Þorleifsson, Ólafur H. Nielsen, Aðalsteinn Snæþórsson, Þorvaldur Björnsson, Finnur L. Jóhannsson og Hallgrímur Gunnarsson hafa aðstoðað mig við fálkarannsóknir á Norðausturlandi á liðnum árum. Daníel Bergmann léði mynd af fálka. Rannsóknirnar hafa verið kostaðar af Náttúrufræðistofnun Íslands, The Peregrine Fund, The National Geographic Society, Rannís, Arctic Institute of North America, Andrew Mellon Foundation og E. Alexander Bergström Memorial Research Fund. Náttúrurannsóknastöð við Mývatn hefur veitt aðstöðu vegna úti- vinnu. Miklu fleiri hafa komið að verkefninu á einn eða annan máta og kann ég öllu þessu góða fólki bestu þakkir fyrir. Finnur Guðmundsson (f. 1909, d. 1979) og Arnþór Garðarsson, sem hér er heiðraður, voru frumkvöðlar á sviði rjúpnarannsókna á Íslandi. Þessir góðu drengir voru og eru mínar fyrir- myndir í fræðunum.
