Creator Transcript
  • Ondatra. Enemies:- At Lang's saw another instance of a black bear attempting to dig out a rat nest. Behavior:- At most of the bank dens we note a new behavior, almost [word crossed out] small piles of muck + bottom debris have been carried from the water + placed on the ground overlying the burrows. This seems to me to be a manifestation of the same instinct to build that we see at this season in house-living rats + in beavers. I do not know whether it is the young or the old rats that are doing this but from the size of the "bundles" suspect the latter. Holes in the roofs of tunnels are plugged with the same debris. Lang's Post. Aug. [August] 11, 1947. Last night we took 5 rats in the six traps set out this [word crossed out] in the morning + we set out another 17. See over the page for layout of lake + traps.
