From reader Roberto Buonfante comes this “natural” domestic pair and their young, in Italy: a Buteo X Buteo (Redtail jamaicensis x Ferruginous regalis) mated to a Harris (Parabuteo–!– unicinctus) and their first of several successful clutches.
Seems they might make great hare hawks! Roberto writes:
“… the Harris [and] the red/ ferr. were placed in the same aviary to moult because they were tolerant of each other. When the female started to carry material he obviously understood and gave them the chance. The day he candled the eggs he was in shock. We are talking about natural captive breeding of Buteo mix crossed with Parabuteo. I know the breeding was repeated 2 times in the same season, another oddity considering they were raising their young.
“He had a hard time to sell them and like always once gone everybody wanted them.
.. Do not remember if he had both sexes, I would assume yes considering there were several chicks.
