Ontbirds subscribers, Good numbers of Bonaparte's Gulls (300+) have been coming and going and loafing in the bay to the east of Thickson's Point off Crystal Beach Boulevard (at distances anywhere between 200 - 500 metres) all afternoon (making it hard to get a precise number of Bonaparte's Gulls). About 3:20 p.m. I discovered an adult Black-headed Gull among them. The bird has a full brown hood and red bill and the dark undersides to the primaries are easily visible in today's sunny conditions (although it has not been flying very often). It is probably easiest to pick out simply by size alone and is as often found among Ring-billed Gulls as with the Bonaparte's Gulls. There are also 8 adult Little Gulls found among the many Bonaparte's Gulls. Also seen were 2 Iceland Gulls (adult and first-summer), 4 Common Loons and 1 Red-throated Loon (quite distant). All are best viewed using a scope. To my knowledge, there have been no sightings of the Fish Crow or Common Ravens seen at Thickson's Woods the last couple of days. This morning it appeared that there were 2 singing male Cerulean Warblers in the woods. Warblers have just started getting somewhat active again in the last hour. To reach Thickson's Woods take exit 412 from Hwy 401 and go south 2 km on Thickson Road S. Park at the cul-de-sac at the bottom of Thickson Road. The road blocked to traffic just north of the cul-de-sac (Waterfront Trail) leads east to the entrance to Thickson's Woods on the right a few hundred metres ahead. Walking south through the woods leads to the lakefront.
