Bird populations at Yale Forest have increased since 1985, but the amount of
variability among individual study sites has also increased. As the figure shows,

Unlike continental trends, which show that birds have declined by 30%, forest birds in northeastern Connecticut have undergone a 20% increase. Read about this and more in Bird Conservation Research's October newsletter: http://www.birdconservationresearch.org/pdf/bcr%20newsletter%2021-4.pdf.
