Dick Forsman (http://www.dickforsman.com/content/view/26/63/) schrijft op zijn website over een broedgeval Buizerd x Ruigpootbuizerd. Zou slechts een keer eerder beschreven zijn.

Buzzard hybrids in Finland in 2006
On May 7th, 2006, bird ringer Erkki Lamsa stumbled across an occupied raptor's nest in Ylivieska, C Finland, when monitoring his study area. An adult female Common Buzzard Buteo buteo was seen by the nest, while the attending male was a Rough-legged Buzzard B. lagopus. The nest was then subsequently visited on a regular basis to follow up the nesting. The pair managed to rear three young to ringing age and on the last visit on 30th of July two fledglings and both adults were seen near the nest.
This is only the second time ever hybridisation between these two species of birds of prey has been documented. A similar case was reported and later published from Norway in 2005, where a male Common Buzzard and a female Rough-leg reared also three young.
This current case will be published elsewhere.
