These long-legged shorebirds can be found in season along the rocky limestone bed of the Trent gorge above Ranney Falls, on the west flank of Ferris provincial park in Campbellford. The lesser yellowlegs was identified but once, on 16 August 1999. Four greater yellowlegs were noted on 8 September 2007. In spring 2012, as many as 16 greater yellowlegs were noted grazing in the shallow water on the limestone, on seven days between 23 April and 12 May. This is plausibly the spring migration "window", while the earlier observations represent the fall returns.
The two yellowlegs species breed in the far
north of Ontario, from the Hudson Bay Lowlands westwards to Manitoba
(Cadman et al., 1987, pp.524-525).
This is consistent with our limited field data.
The later edition
(Cadman et al., 2007, pp.224-227)
reinforces this image of these far-travelled birds.
The two species are uncommon spring migrants
at Presqu'ile park in April-May, and return over an
extended period from July to October or November
(LaForest, 1993, pp.133-134).
A similar migration tale applies
also to the Kawarthas
(Sadler, 1983, pp.74-75).
