The cormorants catch fish without being able to fully swallow them, and the fishermen are able to retrieve the fish simply by forcing open the cormorants' mouths, apparently engaging the regurgitation reflex. Summary statistics of observations by breeding status category for the Double-crested Cormorant in Minnesota based on all blocks (each 5 km x 5 km) surveyed during the Breeding Bird Atlas (2009-2013).

Widely perceived as a “menace” to local fish populations, the Double-crested Cormorant was routinely molested and shot at in its nighttime roosts during migration and in its nesting colonies during the breeding season. A review of historical records, however, suggests that prior to the 1900s, the Double-crested Cormorant was present in numbers far greater than those observed today, even with the significant increase witnessed in the past 40 years (Wires and Cuthbert 2006). Cormorants are magnificent birds, part of our ecosystems, just like humans. Wires, Linda R., and Francesca J. Cuthbert.

Sub-adults have a variable amount of white in the underparts. Among the principal issues raised are concerns that cormorant populations are impacting local fish populations, decimating fisheries’ stocks at aquaculture facilities and natural ponds managed for bait fish production, negatively impacting vegetation at nesting colonies, and serving as a vector for diseases such as West Nile virus and Newcastle disease (Minnesota Department of Natural Resources 2016). Based on this information, program staff issued a series of five reports that tracked the distribution and abundance of all colonial-nesting species from the mid-1970s through 1985 (Henderson 1977, 1978, 1984; Henderson and Hirsch 1980; Guertin and Pfannmuller 1985).

The cormorants catch fish without being able to fully swallow them, and the fishermen are able to retrieve the fish simply by forcing open the cormorants' mouths, apparently engaging the regurgitation reflex. Hopefully, a more informed and conservation-conscience citizenry in the twenty-first century will ensure that control efforts are only undertaken when absolutely necessary and that the Double-crested Cormorant, like all fish-eating birds from loons to grebes to pelicans, will always continue to have a proper place in healthy ecosystems.
