We are pleased to announce the winner of our September 20th Monday Nature Mystery, Dave Boltz!

Congratulations Dave for correctly identifying the call of the Blackpoll Warbler. Their vocalization is often referred to as ‘nature’s hearing test.’ It is very high-pitched and often difficult to detect. According to a recent article in The New York Times, their breeding range has shifted 400 miles in the past 45 years. To learn more about Blackpoll Warblers, visit our good friends at the Cornell Lab of Ornithology
