The Hamilton Study Area is a circle with a radius of 25 miles (~40.2 km) that is centred on Dundurn Castle in Hamilton, Ontario. It is the official area of study for the Hamilton Naturalists Club, and many local birders keep an HSA list. For some, this is their most revered bird list. For me, it is a few rungs lower (following my World List, Canada List, Ontario List, World Photographed List, Ontario Photographed List, and a few others), but I always jump at the chance to add a new species to my HSA list. I grew up in south Cambridge, which is situated within the western boundary of the HSA. My formative years as a birder took place predominately in the HSA; not only in south Cambridge, but also in south Guelph where I attended university. In the years since, I have lived elsewhere, though the HSA has always been just a short drive away.
In recent weeks the HSA has produced several fantastic rare birds; the crown jewel being the Yellow-browed Warbler (Canada's 2nd ever record), but more on that bird in a minute. All told, I have added three species to my HSA list recently, bringing it up to 309. A good start.
