continuing the theme of subspecies, morphs and all that malarkey, I thought I'd introduce another factor that could make your birding experience evermore exciting!
Everyone likes Shrikes; they have stunning plumes and an unusual habit of hoarding their prey; they're relatively easy to identify too - or are they?
While out in Norway we managed to chance upon three Great Grey Shrikes, an adult and two 1st years. Unfortunately I lost the pictures of the adult bird but am still able to study the other two birds in detail. I managed to ring both an adult and juvenile and feel extremely lucky to do so, thanks to Nigel and the team's kindness.
Anyway the first juvenile we caught was a typical ssp excubitor, exhibiting diagnostic tail pattern and limited white in secondaries along with the typically darker/colder feel. Bear in mind the photos I am attaching have not been edited in order to give better appreciation of tones rather than making it look nicer; that's science!
