Savannah Sparrow (Passerculus sandwichensis) Science Article 7
abstract
Van Koersveld (Proc. 10th Intern. Ornith. Congr.: 592-594,1 951) demonstrated that digestion in Corvidae continues for 20 to 30 minutes after death unless stopped in somemanner. He also demonstrated that soft-bodied forms such as earthworms were completely digested within that time and wireworm larvae were nearly gone in the same time. Harder forms were less completely digested in that time.
