Abstract: The primary objective of this study included describing the breeding season diet of goshawks in Minnesota using a direct observation technique (i.e., time-lapse video photography). Time-lapse video recording systems were used to collect food habits information for northern goshawks in Minnesota during the 2000, 2001, and 2002 breeding seasons. I identified species and frequency of prey delivered to nests, quantified prey diversity, diet equitability and similarity among nests, and quantified provisioning rates and biomass of prey delivered to nests. Furthermore, I examined relationships between prey diversity and composition, diet equitability, biomass delivered, and delivery rate among nests.
