Could these grey wagtails be nesting by the lake?

Question

there are some grey wagtails at my local park. Yesterday I was watching them and, on seeing me, they flurried away into the side of the bank and disappeared. Is it pssible their nests could actually be in the bank, or do they nest higher up in trees?

Answer 1

It's likely they are nesting there. On the following website, it says, "Grey Wagtails usually nest near shallow, fast-flowing streams, waterfalls, mill-races, lakes, canals, etc. They build their nest in hollows or crevices out of twigs, grass, and moss."

Here are some pic's of Grey Wagtails nesting (about halfway down the page).
