I began my field observations on Thursday, February 4, 2016 at 13:00. It was a beautiful day. The sun was out, the air was calm and the temperature was in the high 40s. I entered Centennial Woods Natural Area in Burlington, Vermont through a small path off of Grove Street. I sat in one spot in an eastern white pine stand for approximately 30 minutes. I heard a variety of different bird calls including Northern Cardinal, White-breasted Nuthatch and Tufted Titmouse. There were also several other calls that I was not familiar with. The only identifiable birds that I clearly saw were 3 Black-capped Chickadees that were jumping around on lower branches of the pines. One chickadee jumped onto the ground in front of me and pecked at the ground before flying away.
On Friday, February 5 at 07:30 I continued my field observations. It was a cold, cloudy morning with a wind out of the west. I was able to identify American Crows, European Starlings and American Robins in the parking lot behind Jeffords. There were about 25 crows that were all flying in the same direction, north. Multiple European Starlings flew overhead and one perched on the rudder of the University’s wind turbine. The American Robins were feeding on crab apple trees that lined the side of the parking lot.
The majority of the birds seen that morning were conjugated around a bird feeder in Centennial Woods. The feeder was located in a subtle ecotone between a deciduous forest and an eastern white pine stand. There was a small stream that ran through the area. White-breasted Nuthatch, Tufted titmouse and Black-capped Chickadees were seen occasionally feeding on the seeds. The birds were calling frequently as a result of an owl call played through speakers.
Mallards and American Black Ducks were spotted in a retention pond just outside of Centennial woods. These were my favorite birds seen that morning. Two pairs of mallards slowly swam around the outside of the pond. The American Black Duck was swimming amongst the Mallards. It stuck its head under water a few times before quickly returning for air.
A second bird feeder was visited in Centennial Woods. On the way to the feeder a Cooper’s Hawk was briefly seen flying over head. The feeder was located near the edge of the natural area. Many sumac trees were present along with other deciduous trees. Northern Cardinals, American Goldfinch and Downy Woodpeckers were sharing a single small tree adjacent to the feeder at one point. The birds came alive with chirps and calls after recorded bird calls were played through a speaker.
