Dakota Science Center participating in bur oak acorn collection study This fall the Dakota Science Center is helping the Cornell Lab of Ornithology by participating in the bur oak acorn collection study. Mature acorns from bur oaks are being collected across the Midwest to determine their distribution. The data collected will help the Cornell Lab of Ornithology determine the availability of this food source for birds. To participate in this study email Laura Munski (lmunski@yahoo.com). She will send you the bur oak identification file and the instruction file. You and your family can collect bur oak acorns as a fun science activity. -- Laura Munski, executive director, Dakota Science Center.
