As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Eagle successfully raises chicks from two nests


An eight-year-old male White-tailed Eagle known as Turquoise Z has been travelling between Angus and Fife visiting two nests, more than 28 miles apart, and raising chicks with two different females, RSPB Scotland has announced.

This unusual behaviour, known as polygamy, is rarely recorded in sea eagles. It has been seen on the west coast of Scotland on a handful of occasions, but these nests were just a few miles apart and the demands of providing enough food for both nests always resulted in failure.

Despite the vast distance between these two nests, however, there has been a successful outcome. In Fife, Turquoise Z raised a female chick tagged Blue X with his usual partner; he raised a second female tagged Blue V at the nest in Angus with a new partner.

Turquoise Z was released in 2009 as part of the east Scotland reintroduction. It has been breeding in a Forest Enterprise Scotland Woodland in Fife since 2013 with a female released in the same year, known as Turquoise 1.
