Abstract
On 1 June 2019, the first recorded breeding by Red-necked Grebe (Podiceps grisgena) in York Region, Ontario, was established when a nest with one egg was found at the Moody Drive storm - water pond in the City of Vaughan. Although this nest was unsuccessful, a pair returned in 2020 and made another six unsuccessful nesting attempts. Also in 2020, another pair was found at the New Enterprise stormwater pond in Vaughan; they too made multiple unsuccessful nesting attempts. Both sites were reoccupied in 2021, and this time the pair at Moody Drive produced one young. In all three years, another pair of birds was also detected at Phillips Lake in Richmond Hill, also in York Region, but nesting was not confirmed. These events, following the first confirmed nesting record at a sewage lagoon in Durham Region (just east of Toronto) in 2018, involved a novel nesting habitat for this species, and perhaps a move towards usage of inland sites in southern Ontario, as opposed to sites along the Lake Ontario shore.
