I am surprised we haven't had more robin nests in our yard - such a perfect place to build - ripe currants and raspberries near by to eat. And my organic garden is a great source of worms. The bird bath provides a nice drink and a place to cool off.
I had no idea that robins built nests this late in the year so I did some research and found out that they build 2 to 3 nests per year - one in the spring and one in the summer here - probably a third one a little further south. They do not reuse the nest - once the young have left the nest, it will be abandoned.
We are all looking forward to watching the young grow once they hatch.
