The term "peep" refers to the 5 smallest sandpipers in North America- including the Least Sandpiper.
The terns reside on a small lake in Waubamik on the outskirts of Parry Sound. The lakes name is Trout Lake but that is not very significant as about 300 lakes in the area go by that name.
Look up Waubamik on google maps. Zoom out 1 size and look to the south west. Thats the lake with the common terns there. They live on little island. However, this isn't a great birding spot. The best birds I've seen there are broad winged hawk, merlin, scarlet tanager, veery, brown thrasher, rose breasted grosbeak, butterbutts, b&w warbler, american redstart and common yellowthroats.
