Research Wildlife Biologist


Dr. George M. Linz is the Field Station and Project Leader for the North Dakota Field Station at the National Wildlife Research Center (NWRC). 

Dr. Linz has led multiple studies in basic and applied wildlife biology, including (1) investigations of common raven impacts on the endangered California Least Tern at Camp Pendleton in southern California, (2) prevalence of avian-borne diseases in dairies and feedlots, (3) use of aquatic herbicides for altering roost habitat favored by blackbirds in North Dakota, (4) migration patterns of blackbirds in relation to sunflower damage, and (5) use of alternative feeding sites (wildlife conservation sunflower plots) for reducing blackbird damage to crops. Additionally, Dr. Linz's expertise on the biology of blackbirds has led to collaboration with international research universities on basic studies related to evolution of blackbirds.

Additionally, Dr. Linz is an adjunct professor of zoology at North Dakota State University where he has served as Study Director and Major Advisor or Co-advisor for 30 graduate student studies.
