Many larger birds reuse their (chick hatching) nest over and over again in successive years. Indeed to combat parasites, the Bald Eagle will keep adding a layer atop their nest until it is so large that the wind brings down the tree. At the other extreme, hummingbirds build a new nest each year. Between these sizes, birds might build new or reuse an older nest. The robin builds new (see previous posting, blog.kootenay-lake.ca/?p=34611), and the Eastern Kingbird reuses.
Indeed, yesterday, I found a Eastern Kingbird incubating in the same nest which it had been feeding chicks in last year on July 16, (blog.kootenay-lake.ca/?p=33529).
I will have watch it for the pending chicks.
A Eastern Kingbird incubates eggs in the same nest it used last year.
Nice to see it made it back.
