Remarks: The number of species exhibitingbreeding evidence in this plot dropped back down to35 this year, which is the same as in 2006. Otherwise,not since 1984 was the number of species this low.Last year, 41 species were found. The average of theprevious 10 years is 43. Surprisingly, the total numberof territorial males increased somewhat to 76.5. Lastyear, this plot produced 69.0 territories, and in 2006 ithad 68.5. The average of the previous 10 years is 80.5territories. The most abundant species this year wasRed-eyed Vireo with 12.0 territories. Last year, theywere the third most abundant species with 9.5territories. In 2006, they were also in third place butwith only 7.0 territories. They have clearly rebounded.The second most abundant species this year wasOvenbird with 11.5 territories. They were also insecond place last year with 10.0 and in 2006 with 9.5territories.

Last year, they werethe most abundant species with the same number ofterritories, and in 2006, they were also the mostabundant species but with 11.5 territories. These threespecies have consistently been the top three mostabundant in this plot for many years, even thoughtheir order flip-flops. Overall, Veery numbers havebeen the most stable.
