Junco nest

This is the nest that a junco whose picture I posted a few days ago was making with its partner. And now they have four eggs.

I knew the nest was there but I had not seen the birds in a few days. Today I thought I should try to mow the lawn, and I would skirt the area with the nest. But one of the juncos was present and became very distressed at my presence, so I gave up mowing at all.

Each egg is about 1.5cm long.
