Golden Lake is one of many lakes in Ontario that have seen an increase in the number of nesting cormorants over the past few years. These birds are not really an invasive species in the normal sense because they are indigenous to our region. However, toxic contamination in the lakes caused egg shell thinning and just about eliminated the birds from the province. In some ways the return of the cormorant is a sign of improved water quality.
However, the populations have increased so fast that their status as an endangered species has being challenged. The Ontario government has authorized hunting of the cormorant starting in 2020. For more information about the rules and regulations governing the hunt, click here.
