Just east of the arboretum is a ‘seed farm’ operated by McGill and on their land is a large seasonal(ish) pool that I had been tipped off held some interesting ducks travelling through the area. I approached carefully, on foot, only to find that the ducks were very skittish indeed and were not going to let me get any closer to them than 100 yards at best … I am going to guess that they associate men on foot with men with guns. However, before they took to the air I was able to determine that there were a half dozen Green-winged Teal, another nice tick for the year. The head colours and markings were quite clear in my binoculars but rather less so in the photographs I managed to snatch from afar.
Prior to that I had been wandering in the arboretum in search of the nesting Great Horned Owl … well, I found its nest easily enough very high in a maple tree but the bird was either not there or was well hunkered down, something they are good at. So I claim a nest tick but will have to return for an owl tick.
