3/19 Shelburne Farms in Shelburne Vermont
On Monday, March 19th, I visited Shelburne Farms and walked along the walking trails. I visited the farm around 11 am and walked around for two hours. The temperature was around 28-30 degrees F. I saw some Black-capped Chickadees and White-breasted Nuthatches as well as a two Red-tailed Hawks. The Black-capped Chickadees and White-breasted Nuthatches were near the beginning of the walking trails on bird feeders. The Red-tailed Hawks were flying in an open clearing in the middle of the walking trails.
During my walk, the Black-capped Chickadees, and the White-breasted Nuthatches kept to their own trees and didn't really interact with each other. They barely interacted with their own species either. I watched the bird feeder for 15 minutes and there was only ever one bird on it at a time. The Hawks, however, did interact with each other. They flew in big circles around each other and then took off into opposite directions. The Hawks were a pair trying to look for food, which is why they flew away from each other.
The plumage of the Black-capped Chickadee is that they have a black head and bib. The back of the bird is grey and the belly is white. The White-breasted Nuthatch has a blueish/grey back with a white belly. They also have a black head. Lastly, the Red-tailed Hawk has a dark brown back and a streaked white belly. They have a red tail and dark wing tips. The Black-capped Chickadee and the White-breasted Nuthatch blend in with the wood of trees during the winter. So that helps to protect them from predators. The Red-tailed Hawk is hard to see which helps them sneak up on their prey. The Red-tailed Hawks were hunting for food. That behavior fits more into the circadian rhythm because hunting is something that these birds do daily. They need to eat every day and not just when the weather changes, which means that it is a circadian rhythm behavior.
