During the first few minutes of this observation, the father sat on the eggs incubating them. About 8 minutes in, I observed the mother return to the nest. This was when I was able to distinguish the mother and father because I noticed the size of the mother was a lot smaller than the father, who was laying in the nest, incubating the eggs. After a minute, the mother flew away again and left the nest. She did not return during the rest of my observation period. The father did not do any nest building while laying on the eggs.
