3/16 Birdwatching in Mansfield, MA

March 16 from 12:00 pm -1:00 pm
Sunny, 50°F, low wind
Habitats: clearing in a mixed coniferous forest adjacent to an open horse farm

I arrived at my birdwatching location a little before noon. While this is not an optimal time for birdwatching, I was successful in seeing and hearing birds due to the close proximity of many different habitat types. I observed the birds from a clearing that likely once served as an access road in the middle of a conifer-dominant forest. The forest was directly next to open shrubland and a large field that was once a horse farm. At first, I encountered several generalist species. I witnessed 2 American Robins chasing after each other, a typical behavior when establishing territory. This phenomenon tends to occur between 2 males or 2 females. I heard consistent calls from Tufted Titmouse, Northern Cardinals, Dark-eyed Juncos, Blue Jays, American Crows, and one Golden-crowned Kinglet. For the most part, these birds were not visible.

Red-tailed Hawks are active and highly visible during this time due to their ecological niche as a predator. While most songbirds forage in the morning and take shelter throughout the day, hawks are diurnal hunters with few predators. I spotted 2 Red-tailed Hawks circling over the open field searching for prey. I have heard their calls in this location rather frequently, but they were extremely quiet during their hunt.

While my attempts at “pishing” were unsuccessful, I was able to go back and forth with a Northern Cardinal by whistling. The responding cardinal drew closer and closer throughout the duration of the hour. At the end of my watch, the cardinal flew close to where I was watching, and turned out to be female. It is possible that she approached to mate, as March marks the start of the Northern Cardinal’s breeding season. The male Northern Cardinal’s bright red plumage is the most striking coloration I encountered on my trip. This plumage reflects sexual selection from female cardinals, who prefer the reddest males. This comes at a tradeoff, as the most sexually preferred males stand out the most to predators. The plumage of the Dark-eyed Junco, on the other hand, is useful for remaining camouflaged and undetected in its forest habitat. While their dark plumage is more discreet, these juncos perform courtship rituals in which they flash their bright white tail feathers.
