Perspectives–minimizing observer bias in behavioral studies: a review and recommendations

…, KE Morrison, CL Stec, CE Zachau, TM Freeberg - Ethology, 2012 - Wiley Online Library
Since the 1970s, texts on research methods in animal behavior advocate that researchers

Social complexity can drive vocal complexity: group size influences vocal information in Carolina chickadees

TM Freeberg - Psychological Science, 2006 - journals.sagepub.com
One hypothesis to explain variation in vocal communication in animal species is that the
complexity of the social group influences the group's vocal complexity. This social-complexity …

Receivers respond differently to chick-a-dee calls varying in note composition in Carolina chickadees, Poecile carolinensis

TM Freeberg, JR Lucas - Animal Behaviour, 2002 - Elsevier
The chick-a-dee call of the avian genus Poecile is a structurally complex vocal system because
