Officials confirm astonishing comeback of thought-to-be-extinct creatures: 'We're cautiously optimistic'

Maine’s waterways are experiencing a resurgence of loons, the distinctive diving waterbirds known for their haunting calls. This positive trend follows years of population decline linked to both industrial pollution and, more recently, the impact of the fishing industry.

A History of Threats

Maine holds the largest loon population on the East Coast. However, the species faced significant challenges. Prior to the closure of the state’s last coal plant over a decade ago, loons exhibited elevated mercury levels in their blood. More recently, accidental ingestion of fishing tackle has emerged as a key threat, contributing to population decreases.

Did You Know? The loon population count in southern Maine is more than twice what it was when regular monitoring began in 1983.

Legislative Response and Early Signs of Recovery

State lawmakers responded to the threats posed by fishing tackle by enacting bans on types that loons frequently mistake for food. Officials believe these legislative actions are contributing to the observed improvements in the health of the loon population. Conservationists are reporting two consecutive years of increasing chick numbers.

Tracy Hart, a wildlife ecologist with Maine Audubon, expressed cautious optimism, stating, “We’re cautiously optimistic after seeing two years of growing chick numbers. But it will take several more years before we know if that is a real upward trend, or just two really good years.”

Expert Insight: The recovery of the loon population demonstrates the potential for positive environmental impact when legislative action addresses specific, identifiable threats to vulnerable species. It also highlights the complex interplay between industrial activity, environmental health, and wildlife populations.

Population Numbers and Ecological Significance

Currently, Maine Audubon estimates there are 3,174 adult loons and 568 chicks in the southern half of the state – the only area where accurate population counts are available. A 13% increase in the number of adult loons has been recorded over the past decade.

Loons are not merely an iconic symbol of Maine; they play a vital role in the health of the state’s ecosystem. Their presence indicates good water quality and a robust fish population, supporting overall biodiversity.
