Following intensive conservation, the Kirtland's Warbler population rose to approximately how many breeding pairs by the end of 2019?
Answer
Around 2,300 pairs
The Kirtland's Warbler serves as a prominent example of successful conservation efforts reversing a severe population decline. In the 1980s, this species reached critically low numbers, representing the rarest warbler globally, with only about 200 breeding pairs remaining. Through dedicated, multi-organizational conservation work focused on managing their specific habitat needs, the population experienced a substantial recovery over several decades. By the conclusion of 2019, these intensive efforts resulted in the successful boost of the population count to approximately 2,300 breeding pairs, leading to its subsequent delisting from the endangered species status.
