BIRD POPULATIONS - Birdpop.org

BREEDING BIRD CENSUS: 2007on the plot for the first time in eight and six years,respectively. The one breeding flycatcher (GreatCrested Flycatcher) underlines a continuing andsevere decline of this group (81% below the mean).Many once-regular species have not bred on this plotfor several years including Yellow Warbler andWarbling Vireo (five years), and Eastern Kingbird,House Wren, and Yellow-billed Cuckoo (four years).This suggests the plot’s (as well as much of thesurrounding area’s) openness invites sporadicbreeding by some species. To date, 46 species havebred on this plot.4.
