Female is in front of the male. Difference of the head pattern in the male and female can be seen here.
観察結果の詳細
A pair was here by 7:15. Then a third bird appeared about 10:20. That precipitated chases between two of the birds that lasted for about 5 min, with the male of the pair often seen standing tall and observing what was going on. Interpretation: The female of the pair was chasing away an intruding female that was getting too close to her mate. But, in the last few days, there have been several times when three were present without conflict. In those situations, there seems to be a pair with the 3rd bird keeping it's distance.
