Observer: Paul Lauenstein
Observation Date: 5/23/23
Observation Time: 6:20 a.m.
Observation Location: Moose Hill Audubon Wildlife Sanctuary
Common Name: Bay-breasted Warbler
Scientific Name: Setophaga castanea
Comments: Bay-breasted warblers migrate through Sharon in May en route to their summertime breeding areas in Canada. They eat insects and spiders to keep up their energy during the long flight.
Even for experienced bird watchers, bay-breasted warblers are an unusual find. They are typically seen high up in tall trees, making good photos of them especially challenging. Populations of bay-breasted warbler appear to be decreasing throughout their range. The U.S. has seen a decline of almost 3% per year between 1966 and 2014, resulting in a cumulative decline of 74%, according to the North American Breeding Bird Survey.
