Goshawk Triples

As we entered the Voyager RV Resort and its double row of Eucalyptus trees an accipiter was ripping about behind , over and through the trees. The hawk then appeared to our front and at less than 100 feet elevation. It was a male NG with a large patch of white under tail coverts. The hawk had a robust chest. And had red vermiculation on chest, belly, and under wing coverts. Goshawks - males and females, have been observed by me, for 6 seasons in Tucson, starting in winter 2000-01. This same male had stubby wings with pointed wing -tips. The structure of the wings was certainly NG, not Cooper's. Then the hawk was rapidly at at about 150 feet elevation, flapping with very rapid, very deep, and very flexible wing beats. The NG was now circling with another NG. And both were flapping as an NG can flap.
About 3 minutes later I was parked at my RV site, and viewing the area naked-eye. At about 150 feet elevation were 2 female NG. These hawks were the size of Red-tailed Hawks. The hawks were typical female NG, with long wings, and long folded tail.

But wait a minute, something is not right here. I know I observed a mature male Goshawk, so how can it be that I am now observing 2 female NG? About 10 seconds later, with the females separated by about 150 yards, a male NG rapidly climbed to be with one of the females, resulting in Goshawk triples!

At times it is possible to observe NG triples near or within 2-3 miles of their nesting site, as the raptors will often take to the sky with their young. It is a common sighting to observe doubles of NG in Tucson, usually 2 females. For 27 months I have been observing NG in Tucson, starting in winter 2000-10.

And not one person in Tucson is interested in this sighting.
