Field Notes: A Barn Owl in Concord

Cole WinstanleyJalen Winstanley

At dusk on Saturday, January 10th, 2015 the two of us and our father, Carter, saw an intriguing “short-eared” owl at Pine Hill just west of Hanscom Field in Concord, Massachusetts. The bird was hunting over a marsh about 0.3 miles from us. In the low light, we felt in the field that it was a Barn Owl, not a Short-eared. We took about 70 dimly lit photos of the bird, of which only a couple showed discernible marks. Upon reviewing the photos at home, we decided that it was impossible to make a call based only on those photos, especially for such a rare bird as a Barn Owl. We decided to go back and try for better documentation.

The next day, the 11th, Jalen was tied up so only Cole and Carter returned to Pine Hill where they met David and Tim Swain. That evening they observed the bird flying around the exact same area as the day before. Cole took ample photos and, this time, video. That night we were able to conclusively identify the bird as a Barn Owl.

We sent word out to a few locals who were interested in the sighting, and they corroborated the identification as Barn Owl. Some joined Jalen and Carter on the 12th to see the bird again.

On the next two days, various local birders observed the Barn Owl at the Pine Hill location. However, observers noted that the owl spent more time perched and less time flying and hunting than before. Far lower temperatures or accumulating stress due to lack of food may have contributed to this change in behavior. On Thursday the 15th, the sole birder at the location could not find the bird, and additional stakeouts each night until Sunday the 18th appeared to paint a picture of an intrepid southern wanderer that had succumbed to the cold of interior Massachusetts.

However, when David Swain reported an owl from a nearby spot on the following Tuesday (January 20th), a number of the original observers recognized the Barn Owl in his video. It had reappeared! Cole returned the following night and captured some of the first close-range, definitive documentation of the bird. Unfortunately, the Barn Owl vanished after that night, not to be found again despite a number of checks in both locations.

When we first observed the bird, we recognized it as a small raptor coursing over the marsh after dusk. Marks included a darker area that was present not only on the primary coverts, but also running in a rough line down the center of the length of the wing. There was no contrast between the primary and secondary coverts, and there appeared to be a paler leading edge of the wing. The photos showed no black markings on the underwings, including at the wrists and wingtips. With a scope, however, Tim Swain saw grayish marks in these areas similar to those that can be found on female Barns. There was no indication of dark wingtips in the field or in any of the photos. Additionally, there was contrast between the tawny armpit area and the white belly, which is different from the laterally uniform coloring on the underparts of Short-eared Owls. Though not obvious in the field, we noted that some photos appeared to show the distinctive Barn Owl face.

The bird's flight was fluttering with less gliding and more flapping compared to a Short-eared. Its wings were held in a gull-like dihedral when gliding, and it frequently made steep banks that showed off the strikingly white underwings. From the video, Simon Perkins noted that the “proportions (shorter tail, bigger head), wing set (more gull-winged, osprey-like in glide), wing pattern, more deliberate, fluttery flight, long face, [and] the dark line between eye and bill on an otherwise white face” all pointed to Barn Owl (Perkins 2015).

Barn Owls are rare and irregular in Massachusetts, with the exception of Martha’s Vineyard and Nantucket where they were recorded in the second Breeding Bird Atlas (Kamm et al. 2013). On these islands, Barn Owls roost in old barns, tree cavities, and other structures during the day, and hunt over coastal marshes at night. They generally nest in man-made structures.

This sighting in Concord apparently represents the first Barn Owl recorded in Middlesex County since the 1995 sighting in Pepperell by M. Resch (Resch 1995). In Concord or the Concord-Sudbury River Valley, the last previous sighting of a Barn Owl had been in April 1984 by R. K. Walton. Walton notes that Concord had a pair of Barn Owls that were seen by Gardler in the summer of 1959 (Walton 1984, p. 139). A breeding pair and hatchlings were observed by Armstrong in 1945, though all perished in a blizzard (Griscom 1949, p. 235).

Cole and Jalen Winstanley are teenaged birders who live in Concord. They are focused on birding as locally as possible, and have found over 160 species in their yard alone. As such, they contribute signi.ftcantly to the local bird data in Concord, with over 500 eBird checklists in 2013 and 2014. In 2014, they found uncommon breeding birds including Sharp-shinned Hawk, Canada Warbler, and Louisiana Waterthrush all within walking distance of their home. They frequently discover new areas to bird and share them with the local community; their favorite patches in Concord include Estabrook Woods, Great Meadows NWR, Barrett’s Mill Conservation Land, and the Massport 13C trails.
