Double-crested Cormorants (Phalacrocorax auritus) are normally considered a diurnal species. Here we describe cormorants foraging nocturnally in an oxbow lake in Mississippi. We have observed this behavior only once during 30 capture attempts over seven years.

The Impact Of Timber Management On The Phytochemicals Associated With Black Bear Damage, Dale L. Nolte, Bruce A. Kimball, Georg J. Ziegltrum
Proceedings of the Eighteenth Vertebrate Pest Conference (1998)
Black bears forage on Douglas-fir vascular tissue in the spring, and this behavior can be severely detrimental to the health and economic value of a timber stand. Foraging is selective in that not all stands are damaged and, within a stand, one tree may be stripped while its neighbor is ignored or minimally sampled. A series of studies was conducted to assess whether bear selectivity is affected by chemical constituents within vascular tissue, and whether these constituents are affected by silvicultural practices. The results are interpreted to identify forest practices that may alleviate damage, or at least predict where damage …
