There is a pair of ducks, male and female, that comes to my pool now that it is the season. They sit on the edge of the pool or dive in and swim around, sticking close together. They are a sweet couple and have come to my pool for many years now
Today I witnessed a third duck, a male, dive into the pool from overhead. He immediately headed towards the male and female pair as they swam near the southeast corner. The female quickly took off towards the opposite end of the pool.
The newcomer male duck turned to follow her, and the male duck partner followed in rough pursuit. At this, the female duck hopped out of the water and stood on the west edge of the pool.
The male partner of the female duck kept tailing the newcomer duck. Every time the newcomer male headed toward the female duck sitting on the west edge of the pool, her male partner would swim to cut him off. The newcomer male was never given the chance to approach the female duck.
I went back to the kitchen table to finish my noshing. Suddenly I heard water splashing and duck quacking. I went to the kitchen window again to observe.
The female was again (or maybe still) standing on the west edge of the pool and the two male ducks stayed in the water. The male duck partner of the female duck always kept himself between the female duck and the newcomer duck, which was larger.
After a while they both hopped up onto the north edge of the pool. The newcomer duck stood quietly. The male partner of the female duck would stick his head into the pool and then preen himself. The male partner was constantly moving about, sticking his beak into the water or pecking at his wings. The newcomer duck stayed its ground but stood very still and made no moves.
I am now upstairs in my office and have no idea whether the three ducks are still there, but it is interesting to note that as of last observation, the newcomer duck was not able to get near the female duck.
